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).

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”.

Berlin day 2 itinerary during my 2012 trip

A Chicago friend designed my two-day Berlin itinerary, whether he knew it or not. He visited Berlin in March 2012 and sent me an email a week before I left for Europe describing in detail the various facets of the city, including transportation, I should visit. This itinerary is a mesh of his suggestions and what I actually did on Friday, August 31, 2012.

Take the S-Bahn to Olympiastadion. Make sure you note all the unused, but remarkably nice platforms. On exiting the station (toward the east) you get some great views of S-Bahn tracks and covered third rail heading into the city. Walk around the east side of the stadium (and think about how this is a place where Adolf Hitler opened the Olympics and the first television broadcast was done of, making a major plot point in the movie Contact).

Olympiastadion S-Bahn station platforms. The U2 line continues, but some trains may terminate at these platforms for events. 

I walked into the Olympic Stadium, walked 80% of its circumference, and noted all of the statues, some of the stelae, and read most of the historical information stanchions. I saw the swimming arena, which is still in use today (it seems to be a membership club, although not exclusive). The diving platform’s stair design has changed noticeably. The stands haven’t changed: they are covered in what looks like moss.

I then made a long walk to the north and west, past a Berlin football club and equestrian areas, towards the bell tower and Langemarckhalle (which is partly a memorial to the Langemarck battle in WWI, but now an exhibition about how that memorial was a myth and propaganda to encourage students to join the military). The ticket to get into Olympiapark also gets you on the elevator to the top of the bell tower (Glockenturm), giving you splendid views of the city in all directions. In the Maifield between the bell tower and the stadium, men were playing cricket. This humungous grassy area was used for youth rallies during the Nationalist Socialist (Nazi) era. From Wikipedia: “Maifeld (Mayfield) was created as a huge lawn (112,000 square metres, 28 acres) for gymnastic demonstrations, specifically annual May Day celebrations by Hitler’s government.”

After another long walk, I exited the park and made my way to the U2 Olympia-Stadion station (note how the S- and U-bahn stations have slightly different names). This is where the U-Bahn museum is (it has weird hours, don’t expect it to be open), but before you enter, you can walk around the station house and get some INCREDIBLE views of an U-Bahn rail yard and shops facility.

The dreary-looking Olympia-Stadion station east of the Olympic Park.

Next, my friend told me, ride the U2 inbound to Eberswalder Straße (toward Pankow from Olympia-Stadion on the U2 line), and walk under the tracks a half-block south to the little stand with the tables outside. He wrote to me, “Have a spicy currywurst and a beer. You won’t regret it.” I ate it and drank a Berliner Pilsner and I didn’t regret it.

That spicy currywurst and beer under the U2 tracks. 

Next, walk back up to Danziger Strasse. Get on the eastbound/southeastbound M10 tram toward Warschauer Strasse U+S-Bahn stations. But get off at Frankfurter Tor, not the terminal.

Then, do this walk:

You’ll get a good view of some Soviet architecture on Frankfurter Allee, a cute walk through a gentrifying neighborhood with tons of lovely little shops, then see the massive, gritty S-Bahn station, the M10 Tram terminal, and the U-Bahn elevated terminal. (You’ll also walk past the hipster hotel my friend stayed in, Hotel Michelberger.) Then, you’ll end up seeing the Berlin Wall and East Side Gallery just before you cross the water from East Berlin into West Berlin – a profound act, to my friend, considering that it was not possible when we were born – and have a nice walk under the U1 el tracks up to a great elevated station.

I didn’t walk under the U1 el tracks, but instead walked west along the East Side Gallery and then north on Andreasstraße. I stopped at a grocery store to get some grub and then boarded the U5 at Strausberger Platz, changing at Alexanderplatz U+S Bahnhof to the U8, getting off at Pankstraße and walking a block to the apartment I was staying in.

N.B. I bought a day pass to use all transit minus Regio, IC, ICE intercity train service. I could use buses, trams, U-bahn, and S-bahn. I never waited more than 9 minutes for a train or tram. The average wait was probably 3-4 minutes. The day pass cost me $8.20. I was given access to a bicycle, which I rode on Thursday night with my hosts, but after walking around and taking transit all day, I declined to get it. I felt that I would be able to get around the city just as fast (or faster) by taking transit (yes, shocking, I know). I also wanted to ride lots of trains. Here’s the full gallery of photos from the day.

The United States uses way too much text for regulatory traffic signs

Look at these two signs in Berlin (right outside the American embassy). They’re universal across the European Union – and probably in adjacent non-EU countries. The upper one means “yield” and the lower one with the white arrow means “compulsory right turn”. In the United States, there are several signs that mean the same thing. The simplest one we have comes in two forms: symbol and text. That makes two different signs, but there’s a third one. It’s also a text sign but has extra words!

American symbol sign (actually a symbol with text): The sign has an arrow pointing in an upward curve toward the right and the word “only”. Photo by Joseph Dennis. 

Yet there is no need to mix a symbol and a word, as both parts of the message (“right turn” and “only maneuver you can make here”) can be communicated with symbols. In the EU, the right turn sign has two states, both depicted by symbols: off and on. Off meaning you cannot turn right there and is depicted with an arrow pointing right, on a white background, circumscribed with a red circle. The “on” version means you must turn right there and is depicted with an arrow pointing right, on a blue background. (It would be pointless to have a sign saying you can turn right somewhere.)

The next sign is the text-only version of the “right turn only” sign.

And then there’s the most ridiculous one, “right lane must turn right”. In many places, Chicago included, bikes and buses are excepted.

All of the signs depicted above mean the same thing! Why have we developed four unique ways to communicate a single meaning?

While I’m on the subject of right turns, here’re two signs in San Francisco, on Market Street at Octavia Boulevard. Octavia is the end of the Central Freeway, so people driving here are in the mindset of fast highway driving. Cars cannot be turned right here and bicyclists are warned to look out for people making illegal right turns. In other words, “Beware car drivers who break the law”.
