The real Blue Line problem

After reading and discussing the article, The CTA’s Blue Line has a big problem, I’ve decided I need to weigh in on this. Because, guess what, the Blue Line does not actually have a big problem – in

fact, it’s a victim of its own success! That doesn’t mean there isn’t any problems that can’t be addressed, and the author points out a few of them. They are:

So why do I say that the CTA Blue Line is a victim of its own success? What can be done about the real problems the Blue Line does have?

The Blue Line is a Success

At a time when CTA bus ridership is in decline and rideshare (Uber and Lyft) are chipping away at overall CTA ridership, the ridership increases on the Blue Line are an unheralded success. As fare revenue supports operations, the CTA depends heavily on its riders to subsidize the service. Larger urban planning goals like transit-oriented development also support the sunk costs of the CTA by generating a market dependent on transit for at least some of its trips. As a larger policy goal, we should be supporting TOD in every place it can be built, while also doing transit system planning to accommodate market demand. The Blue Line ridership is approaching historic highs. That is a testament to how well the CTA runs the line as much as it is to policy and geography.

What are the Real Problems of the Blue Line

That said, TOD has strained the Blue Line and presented some very real problems. These problems are antiquated train sets, congested stations, ADA accessibility, capacity and power constraints. Let’s take a closer look at each problem:

Antiquated Train Sets

The Blue Line runs the oldest train sets in the CTA roster, the 2600 series. These cars were built in the early to mid 1980s for the CTA, though they’ve been rehabbed since then. The 2600 series train sets are not optimized for efficient passenger loading, due to their perpendicular seating arrangement, which creates bottlenecks in each of the vestibules. The newer 5000 series train sets that are on the CTA Red and Green Lines have longitudinal aisle-facing seating that allow for wider aisles. This seating configuration increases passenger capacity by 20-30% per train car.

The proposed 7000 series cars that the CTA is purchasing will also have longitudinal seating and will replace the 2600 series cars on the Blue Line by 2020. While they will not be open gangway, a style of train design that allows a passenger to walk from car to car seamlessly (shown at right), they should also increase capacity similarly to the 5000 series. That said, the Blue Line has a track configuration which would be optimal for open gangway design, which would drastically improve train capacity.

A more radical solution than open gangway design would be a move to driverless trains. Train sets like this dramatically reduce labor costs, thus allowing more frequent train service all day. Driverless trains could give the CTA the flexibility to run rush hour service virtually the entire day if it wanted, due to the substantial labor savings.

Congested Stations

Weekday ridership at certain stations on the Blue Line have grown significantly since 2002 including California (109%), Western (75%), Logan Square (64%), O’Hare (58%), Division (54%), Belmont (32%) and Damen (29%). My own Blue Line station (Jefferson Park) saw a 7% increase during this time period.

These increases in ridership have contributed to increased passenger crowding per train car, platform crowding at the station level, train delays due to boarding/alighting, all of which may cause some passengers to wait for several trains before boarding. Ways to alleviate this might mean creating more access and egress points at certain stations. Line level improvements might mean extending all station platforms to accommodate 10 or 12 car train sets. A 10 car train allows for 25% more capacity than an existing 8 car train.

ADA Accessibility

Per the Americans with Disabilities Act, public transit providers like the CTA are required to make their system accessible to the public. In practice, this means that any significant station renovations include accessibility features, most notably elevators. The Your New Blue program added an elevator at Addison, though not at California, Damen or Division, where ridership growth has been strongest.

Capacity Constraints

Capacity constraints occur not just in terms of passenger volume, but also in the number of trains running along the line at any given time. And the number of trains run is governed by schedule, availability of equipment, capacity at the rail storage yard, signaling equipment and power capacity. Your New Blue is modernizing signal technology, which will allow the CTA to reduce headway, or space, between trains.

Modernization of the power substations will allow for more trains. The existing Blue Line is constrained by its power plant, which is largely maxed out.

However, even with a modern power plant, the CTA still needs somewhere to store the trains. And storage yard capacity, particularly in Forest Park, would need to be increased to allow more train sets on the line.

When all else fails, a more drastic solution to capacity constraints may involve the addition of railway sidings and/or additional mainline track. Existing Blue Line two-track configuration precludes the kinds of express services that might be offered. Additional mainline track allows the CTA flexibility to segment its route based on passenger volume. It may even allow express O’Hare trains. However, this solution is probably least likely if only because land acquisition and/or tunneling would likely be cost prohibitive.

So how do we fix it?

It is easy to blame the transit for your commuting headaches. And it is even easier to blame new people for crowding your train. But don’t blame the service provider. Demand better service. Because in the end, transit is by far the most efficient way to get around the City of Chicago.

 

Transport Nexus in the Polish Triangle

Looking southwest from the Polish Triangle

Of great interest to this site is the connection, or nexus, between transportation and land use.  One prominent example of this failure of this nexus is at the southwest corner of Ashland Ave., Division St. and Milwaukee Ave., historically known as the Polish Triangle. Now part of the East (Ukrainian) Village neighborhood, this site is commonly known as the “Pizza Hut” site.

Needless to say, it is an abomination that this site was designed (allowed) in such a way as to maximize the use of the automobile when you have the following conditions present:

  • Access to the CTA Blue Line at Division St.
  • The #70 Division bus (running east-west) stop literally next to the property
  • The #56 Milwaukee bus (running NW-SE) and #8 Halsted bus (running north-south) stops across the street.
  • Designated, striped bike lanes on Division St. and Milwaukee Avenue.
  • Rare pedestrian space in the plaza like setting of the Polish Triangle.
Thankfully, this egregious market failure will be rectified.
It seems that after years of waiting, East Village residents will get what they have always wanted: 
In early 2007, immediately after the Pizza Hut was shuttered, a coalition of community organizations lead by the East Village Association set forth four policies for redevelopment of the property. They called for a significant building that was mixed-use, high density and transit oriented.

 

This is, of course, despite the fact that the site faced significant development pressure for a Walgreens and various drive-thru bank facilities. Instead, the community got this:

11 story mixed use building.

The building is an 11-story mixed use facility with ground level retail, second floor office and  apartments above. Reportedly, a coffee shop and bank are among the tenants thus far. 117 apartment units are provided with 35 parking spaces provided, 15 on site. One concession: a drive-thru for the bank using an existing curb cut. Interestingly enough, the 20 off-site parking spaces are in a parking lot adjacent to the property, home to an auto-oriented Wendy’s. The parking will not be available to residents, only for visitors, customers, and car sharing. This seems right.

What I find most interesting is that the developers acknowledge that the apartments are primarily for people who do not own cars. It is a tacit admission that not everyone needs a car, that the site will take advantage of its nexus to so many other transportation options that a car can be just one option among many, rather than catered to and coddled into the site. When you have this many transportation options and an urban environment designed for pedestrians, this concept had to fit within and respect those parameters.  Kudos to the East Village community and developers Rob Buono and Paul Utigard. If more people thought like this we would have more Strong Towns.
