S-Bahn, RER, and Overground

This blog post was inspired by Steven Lucy’s comments on Twitter about three different “regional rail” networks.

New York Governor Kathy Hochul announced in her State of the State speech the other day that the Metropolitan Transportation Authority (MTA), a state authority that operates New York City’s transit, would do a feasibility study for the “The Triboro” (or “Interborough Express”).

The line would use existing freight railroad rights of way to connect Queens and Brooklyn (ironically there isn’t a third borough connection).

Screenshot of a tweet from @RegionalPlan on January 5, 2022. Text of the tweet: “🚨 TRIBORO IS MOVING FORWARD 🚨 @GovKathyHochul just announced @MTA will launch an environmental impact statement for Interborough Express, an above-ground rail line using existing tracks through Brooklyn and Queens, and two-thirds of RPA’s Triboro proposal #StateOfTheStateNY

Transit Twitter has been abuzz, as reusing infrastructure is a really good idea!

John Surico, a professor in New York City, tweeted, “Wonder if NYC is about to have its London Overground moment. An overlooked transit project using freight lines, ended up being way more popular than expected. Since led to new routes, changed where Londoners saw themselves living, and connected otherwise disconnected locales.”

Steven Lucy, a business owner in Chicago, said in response, “Everyone says ‘Chicago RER’ or ‘Chicago S-Bahn’ but I think Chicago is ripe for a London-style Chicago Overground.”

I think all three – RER, S-Bahn, and London Overground – can be grouped as “regional rail”, which constitutes passenger trains running between center cities and their suburbs, stopping at the major stations and a few key stations in the cities, at frequencies higher than commuter and intercity rail and lower than rapid transit.

Regional rail is not quite a walk-up-and-board service, but it’s better than having the hourly or every other hour off-peak service that most United States cities with passenger trains endure.

What are they?

Someone asked Lucy, “What’s the difference between those three?”

Lucy: “My view: they all kind of operate similar service but have different histories.”

I’ll summarize those, and show some of my photos since I’ve ridden and experienced all three types of regional rail.

S-Bahn

Lucy: “Most S-Bahn systems share tracks and stations with long-distance trains (Berlin huge exception) and mainly serve one corridor in city center with branches to burbs.”

Most S-Bahn trains in Germany have the same livery: Blocks of red with white around the doors. The Munich S-Bahn train is shown above. The Berlin S-Bahn, pictured below, is the oddity.

The “S-Bahn” branding, in particular, is used only in German-speaking countries, while in Denmark you’ll find the S-tog. The Wikipedia article for S-train reports a few other networks with similar branding.

S-Bahn trains typically use the same fare structure as the metros (rapid transit) they intersect with. And, in Germany, most S-Bahn trains look the same! Berlin is a major exception, and there are also some smaller networks with unique liveries. German regional transit is owned by cross-state cooperative transit agencies called “zweckverband” (a singular word there) who can operate lines themselves or contract them to other operators, and often S-Bahn services are contracted to DB, the federally-owned railway corporation.

RER

Lucy: “RER was built from scratch post-war, mostly underground in city, to relieve both metro lines and traditional commuter rail.”

When used without qualifiers, RER means “Réseau Express Régional” in French, for Regional Express Network, and the term refers to the hybrid system used in Île-de-France, the region that includes Paris and its suburbs. Many of the lines are interlined, meaning they share routes and stop at some of the same stations. That means that some stations will have high-frequency service and appear to have a “walk up and go” function, but not all trains stopping there are going to the same place.

RER double decker commuter train with level boarding
RER trains are double decker. This model also has very wide doors with level boarding. Sydney’s regional rail trains (SydneyTrains) also have very wide doors and level boarding, which facilities expeditious boarding and deboarding.

The acronym works great in English, though –Regional Express Rail – and it’s being used in Toronto to denote a project to increase frequencies on the GO Transit commuter rail lines.

To call something that’s not in Paris “an RER” would mean that a transit authority is increasing the frequencies and service hours (later runs) of a commuter line and adjusting the fare structure to make it usable for more people.

The goal is to build a transit system that supports non-work trips at any time of the day for everyone; rather than weekday rush hour commuters that many regional trains in the United States (cough Metra cough) serve.

It’s debatable whether the Long Island Railroad (LIRR), Metro North Railroad (MNR), and New Jersey Transit (NJT) in the New York City metropolitan area are a type of “RER”. There are some periods in their schedules, outside of peak periods, when there is better than hourly service, but the two systems do not have fare integration with buses, PATH subways, or NYC Subway, adding a barrier to people using the complete network.

London Overground

Lucy: “Overground took over some underused / disused lines and is kind of a lower-capacity mesh to the complement the Underground, mainly non-radial trips.”

On the Transport for London map, all Overground lines share the same hue of orange, and are identified by their geographic names. S-Bahn lines are typically called “Sx” where “x” is a number, and the five RER lines are letters A through E.

I think it’s neat that the London Overground runs on original embankments between buildings in the city, making its presence very visible, much like the stations on Chicago’s four-track North Side Main Line (all of the Red, Brown, and Purple Line stations north of North Avenue).

One thing that several people noted in the various branches of conversations on Twitter were the effect on land use and development after the London Overground lines opened. I don’t know the details, but some said it accelerated gentrification.

In Chicago, I don’t think converting Metra to an RER system would accelerate gentrification across the system because the current characteristics that inhibit or mitigate gentrification in many of Chicago’s neighborhoods (one of that characteristics is Chicago’s segregation and aldermanic privilege situation, which is better described by the Chicago Area Fair Housing Alliance).

The situation would be a little different if Metra added new stations or restored historic stations, as stations change market and neighborhood development fundamentals. For example, there used to be a station (with trains from Metra’s BNSF predecessor) two blocks from where I live in Little Village. The station area is now John G. Shedd Park.

Metra’s current leadership has indicated their desire to increase service frequency, but remains opposed to electrification (a key change to increase service frequency and operational efficiency and reducing costs) and has not indicated a desire to revamp their operations “style”.

Citibike in New York City differs slightly from Chicago’s Divvy

I visited New York City two weekends ago for a Streetsblog writers conference. I was there for three nights and four days. To get around I put a bunch of cash on a Metrocard to use the subway and JFK Airtrain and I bought a 7-day pass for the Citibike bike-share system.

Citibike and Divvy in Chicago use nearly identical equipment from the same manufacturer, and Alta Bicycle Sharing operates both systems. Citibike sells the 7-day pass for $25, a relative steal for personal transportation costs in New York City – probably any city. Divvy only offers 24-hour and annual passes.

Citibike stations have maps of a better design that matches the walking wayfinding stanchions that New York City’s Department of Transportation has installed. The stations integrate the ad+map board onto the kiosk while Divvy has separated them. I don’t see an operational advantage to either design, but there does seem to be less material used in Citibike’s integrated design which uses one fewer solar panel.

I’ve never used Divvy’s touch-screen kiosk to obtain a single ride code as part of using a day pass so I can’t compare it to interacting with the Citibike kiosk to obtain the ten or so ride codes I needed on my trip. This was the most infuriating part of the experience, which annual members don’t experience because they have a key: the kiosk is very slow in responding to a tap and sometimes the docking bay wouldn’t accept my brand new ride code. You can’t get a replacement ride code for two minutes, preventing quick dock surfing.

The bicycles seem exactly the same: too small of a gear ratio which means a slow top speed and an easy-to-reach “over pedaling” threshold. This may be more important for New York City to have because you must climb 140 feet up the bridges to cross between Manhattan and Brooklyn or Queens while Chicago has no significant slopes. I eventually stopped using Citibike in favor of the subway and walking. I like riding trains almost as much as I like riding a bicycle and cycling in downtown Manhattan is difficult if you’re unsure of a good route to get to your destination. I prefer to not use an app for directions because of how frequently the turns appear meaning I have to inspect the app just as often to ensure I made the right one.

I’d like to see my Divvy key work in other cities where Alta operates bike-sharing. Just charge my bank card on file, applying the lowest-cost pass and letting me bypass the user agreements before purchasing a pass in another city.

Data collection issues in police database design

Please don’t park on sucker (er, sign) poles. And use a good lock. When your bike is stolen, no one but you will care. And the police won’t even know. 

When I asked the Chicago Police Department for statistics on how many bicycles are reported stolen each year, the response was that statistics couldn’t be provided because the database can’t be filtered on “bicycle theft”. I called the police officer responding to my FOIA request to learn more. He said that bike thefts are only categorized as “property thefts under $300” or “property thefts over $300”.

It would be possible to search through the database using keywords, but that would have been an unreasonable use of the officer’s and department’s time in accordance with FOIA laws (FOIA meaning Freedom of Information Act, known as FOIL in other states).

What a poorly designed database.

The Federal Bureau of Investigation (FBI) has Uniform Crime Reporting standards that police departments nationwide voluntarily adopt. It’s mainly a way for the FBI to collect statistics across the country and I assume this program is necessary because of a state’s right to impose its own standards. That sounds fine by me, but it shouldn’t impede collecting data to assist the Department of Transportation, and the Police Department itself, to combat bike theft. The Bike 2015 Plan, released in 2005 and adopted by the Mayor’s Bicycle Advisory Council (MBAC), includes several strategies to reduce bike theft in Chicago.

The FBI has a standard reporting code for bike thefts: 6Xf. Its definition is “the unlawful taking of any bicycle, tandem bicycle, unicycle, etc.”

The Chicago Police Department should upgrade its database to code property theft of bicycles as a “bike theft”. For now, though, advocates and activists will have to rely on the homegrown Chicago Stolen Bike Registry*. If you don’t know the extent of the problem, it’ll be hard to develop any solution.

The Bike 2015 Plan called for a report, by 2006, to be written that determined the “amount and types of bike theft”. We’re in 2012 – where’s that report?

Thinking about New York City

New York City’s Police Department (NYPD) has similar, but more grievous, database problems. Right now the New York City Council is holding a hearing to figure out why the NYPD isn’t investigating reckless drivers who’ve killed people walking and cycling. And I read this about it:

 Vacca’s first question to Deputy Chief John Cassidy, the NYPD Chief of Transportation, was about speeding, and how often drivers caught speeding are charged with reckless endangerment. The answer came not from Cassidy, but from Susan Petito, an NYPD attorney, who politely explained that they simply don’t know, because reckless endangerment charges “are not segregated in the database” and can’t be easily found. Via Gothamist.

Hmm, seems like the same issue the Chicago Police Department has.

* The Stolen Bike Registry has its own issues, which is often because of “user error”, wherein people who submit reports to it don’t provide much detail, especially as from where the bike was stolen.

Bike to work week now, but what about next week?

Groupon mentioned on its blog that 126 employees rode to their Chicago office Monday.

Since the city has a goal of having 5% of trips under 5 miles by bicycle*, how do we ensure those same 126 employees ride their bike next week? Or tomorrow even!

With more of this:

And some of this:

We’ll also need some left turn bays for bicyclists:

This will help cyclists make safer left turns across intersections. As seen in Amsterdam, The Netherlands.

Then we’ll see this:

Happy people riding together in our neighborhoods. With lights at night, for sure.

Oh, we’ll probably need additional bike parking, like this station at Amsterdam Zuid station (think Chicago’s Union Station or New York City’s Penn Station):

Free, underground, double-decker bike parking.

*We’re probably somewhere between 0.5% and 1.5% (of trips under 5 miles by bike). No data’s actually available on this; not for the baseline year of 2006 and most likely will not be available for the goal year, 2015.

The 3-way street

Update June 12, 2011: Added a link to and excerpt from commentary by David Hembrow, a British blogger in the Netherlands.

How does a 3-way street work? Easy, just watch the video.

I like the term “aggressive yield” to describe the situation when a motorist does yield to pedestrians crossing the street, but in a way where they inch forward continually, slowly pushing, with a buffer or air, the people out of the way.

I really like the comment from Tuesday by Anthony Ball:

those red markers are just showing the limits of tolerable risk as established by years of system development. If the collision speeds were higher, those red circles would be far few – it’s simply a system finding its own point of stability.

If you really want to wreak havoc – try to control that system without corrective feedback (eg more rules, lights, controls, etc) and you’ll see the system kill people while it tries to find new stable relationships.

don’t forget that rules, signs, lights, etc have no direct impact on the system – they only work through the interpretation of the users.

What did David Hembrow have to say? David lives in the Netherlands and disagrees with the common sentiment that these conflicts are caused by selfish users.

I don’t see the behaviour at this junction as being about “bad habits”. What I see is simply a very badly designed junction which almost invites people to behave in the way that they do.

Dutch road junctions don’t look like and work like this – they are different for a reason: it removes the conflicts and improves safety. A long-standing theme of Dutch road design is the concept of Sustainable Safety. The concept is to remove conflict so that collisions are rare and the consequences of those which remain are relatively small. Roads are made self-explanatory so that bad behaviour is reduced and the way people behave is changed.

Reading this reminds me of the work of the students in George Aye’s class at SAIC, “Living in a Smart City.” The students attempted, through an intersection redesign, to reduce the stresses that lead to crashes.

Where are the 3-way streets in your city? Grand/Halsted/Milwaukee in Chicago comes to my mind easily. Also a lot of streets in the Loop. Oh yeah, and The Crotch, at Milwaukee/North/Damen.
