Diverging Approach: Six Degrees of Separation (Part 3)

Over the past few weeks, this blog has explored what we’ve been calling the “Grand Corridor”, what should be a high-performing intermodal transit corridor straddling Chicago’s Northwest and West Sides as well as suburban Cook County that, ideally, could connect these working-class neighborhoods to Elgin, O’Hare, and the Loop with fast and frequent transit service, but due to Chicagoland’s byzantine, balkanized approach to transit operations and planning, result in only modest plans that fail to fully leverage this incredible asset.

However, it is the editorial policy of this blog that it does not offer criticism without also offering potential solutions, so to conclude this series, this post will detail a governance proposal to address some of these challenges and set the groundwork for a more efficient, more effective option to better position Chicagoland to operate and build a proper 21st-Century transit network that better levels the regional playing field, streamline processes, and break down harmful silos of governance, all without throwing the proverbial baby out with the bathwater.


If you’re reading this, there is an extremely high likelihood that you are already at least somewhat familiar with two primary pieces of legislation working their ways through the Illinois General Assembly down in Springfield that would both address transit governance issues in Northeastern Illinois: the Metropolitan Mobility Act, supported by the Partnership for Action on Reimagining Transit, which would dramatically transform our governance model by merging the RTA, CTA, Metra, and Pace into a single agency; and a more modest reform bill (that would simply delegate to the RTA some additional limited powers to oversee the three service boards) colloquially known as “the labor bill” in honor of the United We Move labor coalition that is championing the legislation. Much ink has been spilled already in taking deeper looks at both of these approaches; I personally suggest reading RIchard Day’s (pro-MMA) City That Works post about the larger reform efforts and the benefits of the Metropolitan Mobility Act in the context of less-comprehensive reform. However, MMA opponents have also made some very fair critiques of the legislation, most notably the idea that simply putting everyone under the same roof does not necessarily guarantee a more efficient transit operation for riders; any frequent user of the CTA undoubtedly has a few stories about missed bus-to-bus or train-to-train connections even within the same agency. There are also fears that with the MMA’s singular board split between the different “factions” in Chicagoland, someone will get (pardon the pun) railroaded by joint governance. Of course, these fears simply reinforce the existing siloed thinking that got us into this mess in the first place, and depending on who you talk to it’s either going to result in the suburbs running roughshod over the city, or the city running roughshod over the suburbs. In addition to concerns about Naperville calling the shots on the ‘L’, or the Fifth Floor deciding what transit in Will County should look like, there are also concerns from the folks who do the hard work of operating the buses and trains themselves: while union contracts could undoubtedly be resolved eventually, adding uncertainty and requiring new negotiations with any new agency is a level of instability the unions would understandably prefer to avoid.

On the opposite side of the argument, of course, is history: faced with a “doomsday” budget scenario in 2008, Illinois empowered the RTA with additional oversight tasks and duties as part of additional revenues to stabilize transit operations. Today, there’s understandably a healthy skepticism that, faced with a “doomsday” budget scenario in 2026, empowering the RTA with additional oversight tasks and duties as part of additional revenues to stabilize transit operations would not necessarily be a long-term solution. While the RTA’s “Transforming Transit” vision document, for instance, calls on the legislature to empower the RTA to create things like a unified fare product, this overlooks the inconvenient fact that the RTA was empowered by the legislature to create a unified fare product years ago, and has missed the statutorily-mandated deadline by a decade and counting.

While the MMA and the labor bills continue to work their way through Springfield, there is a potential third option that has not yet been fully explored in the legislation, a middle ground that could finally have found its moment: an RTA-like agency tasked not merely with “oversight” but explicitly tasked with managing a unified network and contracting out operations to publicly-owned operating units, which could then remain officially standalone agencies with their own boards of directors and local control of day-to-day operations and service delivery. This is something along the lines of the German verkehrsverbund model, of which Steven Vance has previously written a terrific primer on the subject. Since it can be an intimidating idea (and, of course, an intimidating German word to try to pronounce), let’s walk through what something like that could look like in Chicagoland in a much more user-friendly vernacular.

Introducing: Cartesian

For the purposes of this hypothetical, we will create a “new” agency named CARTESIAN: the Chicagoland Association of Regional Transportation Enterprises, Strategy, Innovation, and Accessible Networks. While it is quite a lengthy acronym, and for legibility purposes we’ll use “Cartesian” in mixed-case in this post, it is meant to be as widely-encompassing as possible, tasked with all aspects of creating a single, unified, regional transit network. From an artistic standpoint, the name also deliberately invokes the Cartesian coordinate plane, an infinite two-dimensional grid stretching to the horizon, which, let’s be honest, is more or less what Chicagoland’s transportation network looks like from the air.

We love our limitless grid, don’t we folks? (Google Maps aerial screenshot)

Whether Cartesian ends up becoming a totally new agency that would replace the RTA, or a public RTA rebrand, or simply a shorthand way to refer to the new tasks delegated to the RTA, is ultimately a political question best left up to the politicians. However, Cartesian would officially become the provider of transit for all of Chicagoland: capital planning, service planning, procurement, communications, fare structures, and more would all become part of Cartesian’s core mission, and the Cartesian board would represent a broad geographic cross-section of Chicagoland, just like the RTA board currently does. To ensure one geographic “faction” could not overrule another, the Cartesian board would be required to have unanimity among its factions, but not necessarily among its full board. In other words, assuming Cartesian’s board would be constituted the same way as the proposed MMA board — 3 gubernatorial appointees, 5 collar county appointees, 5 Cook County appointees, and 5 City of Chicago appointees — board actions would need 11 out of 18 votes, but would require a majority of each appointing unit (2/3rds of the Governor’s appointees and 3/5ths of each of the other three constituencies) to ensure that everyone’s on the same page.

Cartesian, as a “transit association”, would be the sole agency responsible for coordinating present and future transit services for the entire region, including presenting a unified network vision for Chicagoland transit to ensure our entire system functions as a single, cohesive, expansive transit network. With a unified vision, Cartesian can take the lead on applying for discretionary funds and working with agencies like CMAP and our Departments of Transportation to identify, coordinate, and execute capital investment opportunities that are most beneficial to the region as a whole, avoiding potentially expensive duplication — or worse, competition — between projects currently segregated by mode or by operator. Similar to existing efforts by all three service boards and the RTA, Cartesian would also be empowered to help municipalities and neighborhoods create station-area plans and support local efforts to build and enhance transit-oriented development opportunities; unlike the current paradigm, however, Cartesian would be a “one stop shop” for these initiatives, rather than leaving station-area stakeholders to try to figure out who they should be working with based on mode or operator.

The Enterprise System

There is one key role that Cartesian would not have, however: like the RTA today, Cartesian would not directly operate any transit service in Chicagoland. Instead, Cartesian would contract out all day-to-day operations to enterprises, which would be the new name for the service boards. The primary difference between an enterprise and a current authority or service board would be replacing annual budgets with fixed-duration contracts between Cartesian and each individual enterprise. Rather than simply giving the CTA, Metra, and Pace’s annual budgets a thumbs-up or a thumbs-down as they do today (although a “thumbs down” has never been publicly issued anyway), there would be an agreed-upon contract between the enterprises and Cartesian, which spell out key performance indicators (KPIs), required minimum service levels, and incentives for meeting these targets. Contracts would not necessarily be competitive — there’s only a single enterprise that could operate the ‘L’, for instance — but they would provide verifiable, quantifiable, actionable metrics and service standards. By shifting from budgets to contracts, these accountability measures can be consistently managed throughout the life of the contract, with the boards of each enterprise empowered to directly hold accountable their respective management staffs based on contractually-required KPIs and service standards. When contracts need to be renewed, they can then also be renegotiated between Cartesian and the individual enterprises based on changing conditions, along with sweeteners for good performance — and perhaps mandatory accountability for unsatisfactory performance. (Note that “accountability” can take many forms and does not necessarily mean a funding reduction.) These contracts can also provide more stability with discretionary funds while also providing for reviews of discretionary fund allotment at regular intervals to help ensure the various enterprises are all appropriately funded based on overall revenues even as operating conditions may change and evolve over time.

Enterprises would be tasked exclusively with day-to-day operations, which also includes things like security as well as preventative and routine maintenance. Since capital planning and programming would become the responsibility of Cartesian, the enterprises would also have no need for bonding authority and would be required to maintain balanced operating budgets. Enterprises also allow for pass-through funding to guarantee each enterprise a financial “floor” — for instance, the Chicago Transit Enterprise could be guaranteed a very high percentage of all sales tax revenues generated within the city proper, with supplemental funds determined by the contracts with Cartesian based on farebox revenues (since Cartesian would own and operate all fare media and equipment) or other revenue sources that will inevitably be needed to bridge the fiscal cliff. With the near-entire focus on simply running high-quality regular service, the boards of each enterprise could focus exclusively on service performance and rider experience issues, providing a direct avenue of accountability both internally within each enterprise and for the riding public; enterprise boards could also include members of organized labor to ensure that front-line employees also have representation in each operating unit.

This is an important distinction between the two sides of public accountability: while Cartesian would be responsible for (and held accountable for) service planning — for instance, regional network planning, procurement, capital project prioritization, and so on — the enterprises would be responsible for service quality, like balanced headways, cleanliness, and reliability. This could ensure additional protection against something like a purely hypothetical scenario where executive staff allows service quality to severely deteriorate but an executive director politically could not be forced out because they have, say, a supposed knack for winning federal discretionary funding awards. While that scenario — again, totally hypothetical and in no way based on recent events — is entirely possible under our current governance paradigm and under less-ambitious RTA reforms, under the Cartesian system those particular skill sets would be entirely separated and responsibilities more explicitly delineated, ultimately improving accountability for service planning and for service quality.

The enterprise system also allows the larger Cartesian model to remain forward-compatible with future operators or entire modes. Maybe someday the South Shore Line joins, or Illinois Tollway becomes part of the fold, or even Divvy or a scooter operator wants to expand their footprint beyond the city proper. Rather than determine where to try to cram any of those entities into the existing enterprises, or make individual municipalities have to enter into new agreements on an individual basis that creates service gaps, Cartesian can simply create a new contract and/or adapt existing contracts at the next scheduled negotiation point.

In the context of this blog series though, service planning is where the rubber really starts to hit the road under the Cartesian model.

Cartesian Service Planning

At its most elemental and speaking operator-agnostically, Chicagoland has four primary modes of transit:

  • Commuter/regional trains (Metra)
  • The ‘L’ (CTA)
  • Fixed-route buses (CTA and Pace)
  • Microtransit (ADA paratransit, on-demand/dial-a-ride, vanpool, e-scooters, bike share, etc.)

Cartesian’s mandate would treat each of them accordingly, creating a single regional network plan and service schedules focused purely on what individual routes (and at what frequencies) would be the most efficient and effective to best serve the traveling public, regardless of who happens to be operating them or where they happen to operate.

As we discussed in Part 2 of this series, the mode with the most restrictions in terms of operating frequencies and schedules is Metra, considering the agency’s reliance on and constraints with sharing tracks with freight railroads. First, Cartesian would work with Metra on an annual or semi-annual basis to establish regional rail schedules based on operating, funding, and labor constraints, and agree to a systemwide framework schedule.

With the regional rail schedule in place, Cartesian would then move onto updating and creating service goals and schedules for the bus network, ensuring bus routes have intermodal connectivity throughout the entire region wherever possible and planning schedules accordingly.

90X Routes

Cartesian’s service planners would identify certain routes as 90x routes. The 90x designation (note: this is not necessarily a route number, but rather an internal categorization) denotes a high-frequency route, which would be defined as meeting the following criteria:

  • The route operates seven days a week, with
  • An average at least six trips per hour (average 10-minute headways) on weekdays, for
  • At least 15 hours a day (5am-8pm) on weekdays, and
  • No scheduled gaps of longer than 15 minutes during the same hours, as well as between 8am and 8pm on weekends.

Routes that would meet these criteria would operate at least 90 trips in each direction per weekday (6 trips per hour x 15 hours), hence the “90x” designation. Given the high frequencies, connections to regional rail trains would be assumed to be convenient enough to support show-up-and-go transfers; accordingly, the operating enterprises for these routes — which likely also would include most or all of the ‘L’ network — would handle scheduling entirely in-house, and the contracts for these routes would measure headway reliability rather than on-time performance. (This also provides an incentive for bus operators to find ways to operate more service, as routes that meet the 90x threshold would be scheduled and controlled internally rather than the enterprise being forced to operate schedules determined by Cartesian’s schedulers and service planners.) Likewise, 90x routes would have no restrictions on operating more frequently than the minimums established above, if the enterprise chooses to do so; this is intended to ensure city residents that Cartesian couldn’t “take over” busy city routes, considering a vast majority, if not all, of the 90x routes would likely be concentrated in Chicago proper. For routes that do not meet the 90x threshold — and, if needed, on 90x routes during early mornings and late evenings — scheduling would be centrally planned by Cartesian to ensure more convenient timed transfers to regional rail trains based on those schedules, as well as timed transfers (wherever possible) between non-90x bus routes.

As part of the regular contract negotiations, bus enterprises (Chicago Transit Enterprise and Pace) would bid on all bus routes, likely at the garage level. While it’s unlikely that the CTE would ever seriously compete with Pace for a collar-county route, and vice versa for routes in the urban core, this process would help ensure more efficient operations in the city/suburban “fringe” (like the Grand Corridor), as well as add a measure of cost control by allowing the two bus agencies to “compete” with each other in some areas without necessarily opening the market to private contractors who could undercut labor agreements. In either case, however, a typical rider would not be aware of the difference: publicly the system would be presented as a single network, using a single fare structure, with coordinated schedules between different routes and different modes, creating a seamless riding experience regardless of which enterprise happens to be operating the bus.


Ultimately, the Cartesian system would solve the problem that the Metropolitan Mobility Act is not guaranteed to solve, and what modest RTA reform efforts by definition cannot solve: existing oversight and coordination of our transit governance network is inherently passive and reactionary. Service boards are of course encouraged to work together and while they all claim to, our current governance structure can do no more than politely ask them to do so: the agency that ostensibly serves to unify the region’s transit network is only able to approve or reject whatever the service boards send them, rather than proactively creating and maintaining a unified network. While it’s true that the public transit needs of, say, 79th Street through the South Side are totally different than dial-a-ride services in rural McHenry County, it also is not a binary of “city transit” vs. “suburban transit”, even if plenty of elected officials (and transit users) on both sides of the 606XX divide may believe otherwise. The Chicagoland region is diverse in every sense of the word (except perhaps topographically), which means our transit needs exist on a broad spectrum of frequencies, modes, and geographies. We can’t afford to continue only hoping for the best that our four different agencies are all actually moving in the same direction.

This series has focused on the Grand Corridor because the corridor is emblematic of all the reasons why our current transit governance and operating paradigm doesn’t work, but also because of the incredible potential the corridor has if we’re able to reorient how we govern, how we operate, and how we fundamentally think about our transportation network as a whole. This is not a hopeless situation; nothing is broken beyond repair, but rather it’s just frustrating and inefficient. The impulse to want to blow it all up and start over is understandable, as is the fear that doing so would take things too far and cause undue disruption and burden. Likewise, approaching the situation cautiously and easing our way into considerable reform efforts is also understandably appealing, but may result merely in reform in name only, with no serious changes and ending up in yet another doomsday governance scenario once again another decade or so down the line.

We cannot afford to go over the fiscal cliff; significant new revenues are sorely needed simply to keep the lights on at our transit agencies, to say nothing of the need for generational investments in transformative transit. However, there is no — nor should there be — appetite for major new investments without also modernizing our transit governance structure, expanding accountability and creating a unified regional approach to improve transit for all of Chicagoland.

For nearly 80 years, Chicago-area transit funding, operations, and governance have been defined in some variation of a looming structural failure and finding a way to prop up the failing system: whether that was creating the Chicago Transit Authority to bring the ‘L’ and bus companies under public control after World War II, or creating the Regional Transportation Authority in the early 1970s to subsidize the railroads struggling to operate commuter service as well as saving failing suburban bus operators, or spinning off Metra and Pace a little over 40 years ago to directly operate suburban transit services, or tweaking board structures and funding formulas in 2008 to keep buses and trains running, every iteration of reforms have been focused on keeping a faltering 20th-Century model sputtering along until the next “doomsday” inevitably comes back around. A quarter of the way into the 21st Century, we have the opportunity — and responsibility — to finally break that cycle by making the effort to start imagining the unified, cohesive, coordinated regional transit network we want, and then determining how we can reform and retool our agencies to get us there.

We are Chicagoland. We are a region that gets things done, whether that’s raising our city out of a swamp, or literally rising from the ashes to become one of the fastest-growing cities in human history, or reversing the flow of an entire river to protect our drinking water, or building a sprawling network of tunnels throughout the region to fight floods, and throughout all of that our transit and transportation networks have always quite literally been the circulation that pumps prosperity and vitality throughout our city, our region, our state, and the entire Midwest. We owe it to ourselves and future Chicagoans and Chicagolanders to do better than just keeping the lights on.

Make no little plans.

Diverging Approach: Six Degrees of Separation (Part 2)

Welcome back to the ongoing Diverging Approach profile of the Grand Corridor, one of Chicagoland’s most underutilized transit assets. In Part 1 of this series we defined the current lay of the land of Metra’s Milwaukee West corridor between Grand/Cicero and Mannheim, a stretch of nine stations straddling the city of Chicago and the Cook County suburbs. Today the Grand Corridor is served by a disjointed mismatch of CTA and Pace bus routes, as well as legacy Metra schedules, that struggle to effectively serve local neighborhoods and communities despite existing, in-use transit infrastructure that connects to both the Loop and O’Hare.

The good news is that each of our major regional transportation players are all are working on improving the Grand Corridor, and in this post we’ll take a closer look at some of these initiatives, and how they fit into other regional improvement initiatives. But an early spoiler alert: different paths forward with different champions pushing different overall priorities has limited upside in the absence of a single, unified, cohesive regional network.

Chicago Transit AUthority

The Grand Corridor lies relatively far beyond the current reaches of the CTA’s ‘L’ network, a little over two miles north of the CTA Green Line and almost exactly equidistant between the two branches of the CTA Blue Line. Unlike certain other Metra corridors in the city, an extension of the ‘L’ system to provide rail service in this part of the city is not an option. As a result, the city portions of the corridor are served exclusively by CTA bus service.

Map of the pre-pandemic CTA bus network, as shown in the CTA Bus Vision Project Framing Report. CTA routes are shown by scheduled frequency, with darker colors/wider lines indicating more frequent service. The Grand Corridor is highlighted in yellow.

One of the preliminary results of the CTA’s Bus Vision Project is the establishment of the “Frequent Network”, a grid of bus routes throughout the city with headways of 10 minutes or less, seven days a week. Within the Grand Corridor, the 54-Cicero will be one of the first routes to see service improvements, namely a 30% increase in service on Sundays. Of course, since Grand/Cicero is a weekday-peak-only station for Metra, this bus improvement will have zero benefit in the context of this corridor. Next winter, the 72-North — a line that somewhat closely parallels the Grand Corridor, but does not interact with it — will also see service enhancements.

CTA Frequent Network map with scheduled roll-out of enhanced service. The Grand Corridor is highlighted in yellow. (Note that the western portion of the Grand Corridor is cut off.)

Perhaps the CTA bus service enhancement with the most untapped potential will be this fall’s enhancement of the 77-Belmont bus, which also ranked among the top ridership routes in 2024. The 77-Belmont terminates a mere half-mile north of the River Grove MD-W/NCS station at a turnaround near the intersection of Belmont and Cumberland Avenues. Despite somewhat recursively defining their service area as essentially “the areas we already serve“, there unfortunately seems to be zero incentive to extend the 77-Belmont to a two-line Metra station1 that is officially within the CTA’s defined service area. While the CTA has recently extended the 9-Ashland bus to a Metra connection at Ravenswood, since River Grove lies outside the city proper, it will be more challenging to get a city alderperson to champion this particular connection to Metra — and, of course, speaking more holistically, relatively minor transit extensions and connectivity should not need to be aldermanic passion projects.

Approximate location of the Grand Corridor overlaid on a cropped CTA Service Area map as seen in the CTA Bus Vision Study Framing Report. The River Grove Metra station is considered an existing part of the CTA service area, as it is in a census tract that is within a half-mile of an existing bus route.

While we want to focus on the future, it’s also important to understand the past. Up until 2006, Harlem Avenue south of Grand was served exclusively by Pace: the 90-Harlem only operated between the [northern] Harlem Blue Line station and Grand Avenue, where the 90-Harlem turned east and terminated at the Grand/Nordica turnaround. Setting aside the Part 1 rant about how the bus turnaround is tantalizingly close to the Mont Clare Metra without actually serving it, this formed a little mini-hub for this part of the Northwest Side: CTA buses on Grand, Harlem, and Fullerton, as well as Pace’s Grand Avenue bus, all had a direct connection; and connections between the northern Harlem Avenue bus (90) and the central Harlem Avenue bus (307) could be relatively easily made by simply walking across the Grand/Harlem intersection2.

In 2006, CTA completed their West Side/West Suburban Corridor Study, a more holistic look at transit service on the West Side and the CTA-served western suburbs. While the headline improvement of the West Side/West Suburban Corridor Study was what would eventually become the Pink Line, the study also ended up recommended extending the 90-Harlem bus south to the Harlem/Lake Green Line to improve CTA rail connectivity to the Far Northwest Side. Unfortunately, there’s nothing in the study materials to suggest that Pace service was ever seriously considered, either as a way to improve said connectivity or in regards to impacts to Pace’s ridership. Since the structure of the RTA essentially leaves every service board up to their own devices (more on that in Part 3), the change to the 90-Harlem ultimately ended up shifting ridership from Pace’s 307 (and, further south, the 318) to the CTA’s 90-Harlem.

12-month rolling averages of weekday bus ridership on the CTA 90-Harlem, Pace 307, and Pace 318 bus routes from December 2003 to November 2024. Following the extension of the 90-Harlem bus to Harlem/Lake, Pace ridership plateaued and never fully recovered until 2017. (Source: RTAMS ridership data)

In the immediate aftermath of the extension, despite steadily increasing for several months prior, Pace ridership plateaued as CTA ridership grew, strongly suggesting that the 90-Harlem was effectively “cannibalizing” Pace’s ridership in the corridor. Prior to the extension, Pace had more riders than the CTA (although that trend was already weakening); following the extension, that dynamic swung in the other direction for the next seven years.

Over the years though, and as overall ridership stagnated, a different trend emerged likely due to the two different focus areas of the two different service boards. As the CTA was forced to rebalance service towards more “core” services in higher-ridership areas of the city, ridership on the 90-Harlem waned; however, for Pace, the 307 and 318 were — and remain — some of their best-performing routes, resulting in modestly improved service and, resultingly, a larger share of overall Harlem Avenue ridership. It took until 2017 for Pace to recover 307/318 ridership to its June 2006 level, by which time for various reasons 90-Harlem ridership had settled back below its pre-extension levels anyway.

Given the proximity to the Mont Clare Metra station, and now that Pace 307 terminates at Grand/Nordica, now would be an ideal time to cut the 90-Harlem back to its previous terminus and create a proper intermodal hub on the Grand Corridor, but…

Pace

…our suburban bus operator is heading in the exact opposite direction. Pace is currently undergoing a systemwide bus “network restructuring project” called ReVision. As of this publication, Pace and its consultant (same consultant who did the CTA’s Bus Vision Study, but not as a unified effort) are looking at three high-level future scenarios for Pace: a modest 10% service enhancement; a bolder 50% service enhancement focused on maximizing ridership; and a similar 50% service enhancement but focused more on providing wider coverage throughout Pace’s service area rather than solely maximizing ridership. (Assuming a future where a 50% expansion is feasible, it’s likely the final plan will be something of a hybrid of the latter two scenarios.)

Unfortunately for the Grand Corridor, Pace seems to be heading down the path of the “east of Harlem is the CTA’s problem, not ours” siloed approach that has more or less defined the RTA era in one form or another. (Important caveat: the scenarios shown below, except the existing conditions, are intended to be illustrative of the network could look like, but are not an official proposal or plan; the concepts specifically regarding the Grand Corridor are cause for concern nonetheless.)

Existing Pace Network
Pace ReVision existing conditions map showing Pace bus routes by frequency. The Grand Corridor is highlighted in yellow. CTA bus routes are shown but greyed out. The city limits are generally very easy to delineate, even if they are not actually labeled.

Briefly recapping Part 1, four Pace bus routes currently serve the Grand Corridor, in addition to six CTA bus routes:

  • CTA 54-Cicero serves the (weekday-peak-only) Grand/Cicero MD-W station
  • CTA 65-Grand serves the (weekday-peak-only) Grand/Cicero MD-W station, is within a few blocks of the (weekday-peak-only) Hanson Park MD-W station, and serves the Grand/Nordica turnaround near the Mont Clare MD-W station
  • CTA 74-Fullerton serves the Grand/Nordica turnaround near the Mont Clare MD-W station
  • CTA 85-Central serves the (weekday-peak-only) Hanson Park MD-W station, assuming a rider is able-bodied and willing to jaywalk across an elevated viaduct
  • CTA 86-Narragansett/Ridgeland (Monday-Friday only) serves the Galewood MD-W station
  • CTA 90-Harlem is within a 7-minute walk of the Mont Clare MD-W station
  • Pace 303 (Monday-Friday only) serves the Franklin Park MD-W station
  • Pace 307 serves the Grand/Nordica turnaround near the Mont Clare MD-W station
  • Pace 319 (Monday-Saturday only) serves the Elmwood Park MD-W station and the Grand/Nordica turnaround near the Mont Clare MD-W station
  • Pace 331 serves the River Grove MD-W/NCS station
  • Pace 330 does not serve the Mannheim MD-W station since the bus runs on a viaduct, not that it really matters since Mannheim is also a weekday-peak-only station
Pace PLus 10

I could have also superimposed the Chicago city limits, but it’s already painfully clear to quickly ascertain where it lies based on the divisions between the CTA and Pace bus networks.

Pace’s “Plus 10” scenario ultimately reduces service in the Grand Corridor, repurposing all 307 trips north of Harlem/Lake to elsewhere in Pace’s network since the 318 covers everything south of North Avenue and the CTA 90-Harlem can theoretically take care of the rest. This decision (and spoiler alert, this is common among all three scenarios), perhaps more than anything else, is one of the starkest shortcomings of these network redesigns: there is only a single bus route on the entire West Side/near west suburbs that connects all three western (“W#”?) Metra lines as well as the CTA Blue and Green Lines — and we’re considering dismantling it. That should be a five-alarm fire for anyone who cares more about creating an actual transit network in Chicagoland rather than maintaining our city-vs.-suburban agency fiefdoms.

Between Metra weekday-peak-only stations and bus lines without weekend service, Pace Plus 10 would include only one seven-day connection between the Grand Corridor and the Green Line (90-Harlem), zero direct connections to the [Forest Park] Blue Line, and only one connection to both the UP-W and BNSF lines (Pace 331).

Pace Plus 50 – Ridership
Pace ReVision “Plus 50 – Ridership” map illustrating a potential 50% increase in overall Pace service with a focus on maximizing ridership. The Grand Corridor is highlighted in yellow. CTA bus routes are shown but greyed out. With the exception of a 319 extension down Oak Park Avenue, Pace would continue to generally avoid operations within the city proper.

Pace’s “Plus 50 – Ridership” concept also truncates the 307 at Harlem/Lake, despite reinforcing Harlem Avenue as a high-volume (and potential future Pulse route) south of North Avenue. More robust service on Pace 331 would benefit the Grand Corridor with more frequent connections at River Grove as well as a new express “spur” to the Forest Park Blue Line via Interstate 290, and a new Metra/Pace transfer point would be established by extending the 319 south down Oak Park Avenue (which does not currently have a bus route), then doubling back to Harlem/Lake. Of course, this connection would rely on transferring to Metra trains at Mars, which is a weekday-peak-only station. (319 would maintain a connection to the MD-W at Elmwood Park, but would require traveling an extra mile or so in mixed traffic on Grand Avenue relative to Mars.) Franklin Park would also benefit from a more-frequent 303 bus, as well as a stronger potential indirect airport connection (Franklin Park MD-W to 303 to Rosemont Blue to O’Hare). Added service on the 330 is once again a missed opportunity with no direct connection (and extremely low frequency of trains that stop) at the Mannheim MD-W station.

Pace Plus 50 – Coverage
Pace ReVision “Plus 50 – Coverage” map illustrating a potential 50% increase in overall Pace service with a focus on maximizing coverage. The Grand Corridor is highlighted in yellow. CTA bus routes are shown but greyed out. To focus more strongly on regional coverage, the Plus 50 – Coverage scenario is somewhat comparable to the Plus 10 scenario in this part of the region.

The third scenario, which focuses on an enhancement of regional suburban bus coverage, would have far more modest impacts to the existing Pace network in this area. In this scenario the existing 311 (Oak Park Avenue) bus would be extended from North Avenue to Mars (which, again, no off-peak Metra service) and terminate at the Shriners Hospital.

Ultimately, despite all three scenarios being based on some level of increased overall Pace service, in this area the differences in the CTA and Pace bus networks would become more stark and siloed, rather than more integrated. With the very important caveat that Pace ReVision is still ongoing, and that the three scenarios are intended to be more high-level concepts, what they represent at this stage should still be considered an ongoing lack of regional network thinking in favor of a continuance of the precise “CTA’s for the city, Metra and Pace are for the burbs” line of thinking that we as a region so desperately need to break out of.

Metra

As an agency that had to quickly come to a reckoning in the COVID era (a transit agency that lives by the peak also dies by the peak), Metra has made some strides overall in at least understanding that the 2019-era paradigm is no longer a workable option post-pandemic. In February of 2023, Metra published their “My Metra Our Future” five-year strategic plan that, among other things, committed Metra to a transition from a “commuter rail” operational model to a “regional rail” operational model, which Metra defined by comparing the following attributes:

Commuter Rail CharacteristicsRegional Rail Characteristics
Operates at a higher frequency during peak periods and a significantly lower frequency off-peakWhenever possible, includes service at regular intervals with consistent stopping patterns throughout the day
Schedules are more oriented to twice-a-day commutersService is not just oriented around bringing commuters to the urban center
Midday and weekend service is relatively infrequentProvides an all-day transportation option for all trip types throughout the region
Trains operate at specific times rather than at regular intervalsSignificant service during rush-hour to meet travel demand, but less frequent peak service than traditional commuter rail

Metra tracks their progress towards the strategic plan with quarterly “report cards” that are published on their website. As of their most recent update (Q3 2024), Metra is making modest progress: systemwide, Metra’s “service restoration rate”, comparing the percentage of trains operated as a proportion of service in 2019, is above 100% on weekends and off-peak on weekdays; weekday peak service is only 84% of 2019 levels, indicating that Metra has indeed made it a priority to restore and improve off-peak service more quickly than their peak-oriented service. The scorecard also tracks the overall progress of Metra’s ongoing Systemwide Network Plan, which is intended to “identify how Metra can better service changing travel markets with regional rail service“. The Strategic Network Plan was considered 35% complete as of the Q3 2024 report card, and Metra says another round of public outreach regarding the Systemwide Network Plan is expected in “early 2025”.

On the Milwaukee West and North Central Service, however, service restoration and improvement efforts have stalled. For instance, the Grand Corridor is the only part of the Metra network that as of now has not yet regained their weekday late evening trains. Pre-pandemic, the last trains of the night from Chicago Union Station on the MD-W and NCS lines departed at 12:40am and 8:30pm, respectively; today, the final departures leave Chicago Union Station at 11:10pm and 6:00pm.

While Metra is able to occasionally add special supplemental service on a one-off basis (e.g., St. Patrick’s Day and DNC airport shuttles), Metra has said that, to add more frequent service between downtown and O’Hare, the host railroads (Canadian Pacific and CPKC — more on that in a bit) “won’t likely agree to a permanent change without infrastructure improvements,” according to an October 2024 Sun-Times article.

As we discussed in Part 1, the Grand Corridor is an interesting piece of infrastructure operationally and historically. The line was initially operated by the Milwaukee Road until that railroad ran into financial troubles in the early 1980s. As a result, in 1982 the Milwaukee Road entered a trackage agreement with the Regional Transportation Authority that allowed the RTA (and later Metra) to operate commuter trains between Elgin, Fox Lake, and Chicago Union Station, under the dispatching of the Milwaukee Road. When the Soo Line purchased the Milwaukee Road as the latter went into bankruptcy, what is now the “Milwaukee District” was not included in the purchase, but instead included a 99-year trackage agreement to allow Soo Line to use these tracks in a similar manner as Milwaukee Road established in the 1982 agreement. In 1987, RTA officially purchased the Milwaukee District from the Milwaukee Road’s successor, albeit with the 99-year trackage agreement to the Soo Line still in effect. Canadian Pacific took over the Soo Line, and more recently Canadian Pacific merged with Kansas City Southern to form CPKC, inheriting the trackage agreement at each transition.

All of this is to say that, if one dives really, really deep into Metra’s filing with the STB opposing the CPKC merger — page 124 — there’s a document that details how Metra is able to get vetoed by a private company as to how Metra operates Metra trains on Metra tracks. Specifically, with the exception of 5:30-8:30am and 4:00-6:30pm Monday-Friday, “[Metra] may not change the schedule without the [CPKC]’s prior written consent”.

It’s also a bit uncomfortable how little the schedules have changed in the last 40+ years; other than train numbers and some station consolidations/expansions, the peak-of-the-peak westbound MD-W weekday schedule is nearly unchanged since 1982:

While a certain degree of these issues can more than likely chalked up to institutional inertia, Metra’s ongoing constraints to increasing service on the Grand Corridor — a line they already own — can best be described as parking-meter-deal-esque.

Illinois Department of Transportation

Like many parts of the city and near suburbs, IDOT has jurisdiction of many of the major streets along the Grand Corridor, above and beyond the three signed state highways (Thatcher Avenue/IL 171, Harlem Avenue/IL 43 and Cicero Avenue/IL 50). Other major crossings of the Grand Corridor under state control include Des Plaines River Road, Narragansett Avenue, and Grand Avenue itself.

Following the infamous 2005 grade crossing crash that involved 18 vehicles and injured 10 people, IDOT began a grade separation feasibility study in 2007. Since then, under the branding of the “Grand Gateway”, IDOT and the Village of Elmwood Park have since been working on advancing plans for an underpass at this location, a $120 million project that recently secured $13 million for land acquisition.

“Alternative 2”, the preferred grade separation alternative as presented in 2022.

While separating the Grand Avenue crossing is justly considered a transportation priority, the state and Elmwood Park are treating this (nine-figure) project as a spot improvement rather than a corridor enhancement. In this case, just 3,500 feet east of this crossing is the Harlem Avenue grade crossing, which also happens to carry more traffic as well as two bus routes (for now, at least).

If we were looking at the Grand Corridor as an actual corridor, this specific project could be the impetus for — or at least forward-compatible with — a larger-scale grade separation that includes Harlem Avenue to increase safety for all road users while speeding up our buses and trains. What’s particularly frustrating is how so many of the issues previously discussed could fall like dominoes if these efforts all lined up:

  • The corridor elevation could ensure that a fourth main could be reinstalled to separate freight and passenger rail traffic, an important infrastructure improvement that could help Metra convince CPKC to allow more frequent passenger rail service.
  • The corridor elevation would also allow (or require) relocating the Mont Clare Metra station to a location more suitable to also serve as a bus turnaround for CTA and Pace buses, creating a targeted intermodal hub to plan a proper, integrated neighborhood bus network around.
  • As part of designing the new station, even in the absence of a fourth main, an island platform could be included to allow express NCS trains between O’Hare and downtown to stop here — which, again, would now be an intermodal transfer point serving both CTA and Pace buses — instead of River Grove.
  • With this transit anchor near Harlem Avenue, the Harlem Avenue corridor — which intersects with and already has convenient stations for the CTA Green Line, CTA Blue Line, Metra Union Pacific West, and Metra BNSF Railway lines — could be properly prioritized by IDOT, CTA, and Pace to provide fast, frequent connections, opening up the entire West Side and near west suburbs to dramatically improved service to the O’Hare area.
  • With just a little bit of creativity — considering it lies just three miles east of Harlem Avenue — we could connect this Harlem Avenue line to Midway instead of the current 307 terminus at SeatGeek Stadium, which would be downright transformational for massive swaths of the entire Chicagoland region.

But instead, with four different transportation agencies going in four different directions because each of them are focused on the specific niche they specialize in, here we are, with so much potential just slipping through the cracks. Since this corridor isn’t fully city and it isn’t fully suburban, it doesn’t fit neatly into one of those silos we’ve built for ourselves over the decades, so we simply don’t do it.

This series of posts is called “Six Degrees of Separation” because these four major players — combined with the two designated regional players that should be tying them all together, namely the Chicago Metropolitan Agency for Planning (CMAP) and the Regional Transportation Authority (RTA) — have each been going their own way for too long, setting the table for the crisis we’re in now. While the current focus has been on the funding crisis for transit operations, and the governance reforms that will (hopefully) accompany a (hopefully) massive infusion of new funding into regional transit operations, what we really have is a crisis of vision, and a crisis of action: we need to be able to do big things again, and that starts with dreaming of the big — and even some of the more modest — things we want to make realities.

In Part 3, we’ll end on a high note by taking a look at what some of the current governance reform efforts could mean for the Grand Corridor, and present a potential new way forward for a transformative new vision for Chicagoland transit.

  1. Extending the 77-Belmont due west to the Franklin Park MD-W station would also accomplish the goal of connecting the route to both Metra routes since the NCS line also has a station at Belmont Avenue, but the extension would be a bit longer, go outside the CTA’s service area as currently defined, and may result in service delays in case of freight train interference at the grade crossing. Repurposing some of the existing River Grove Metra parking as a bus turnaround would allow the 77-Belmont to avoid crossing any additional tracks at-grade. ↩︎
