Every transit agency across the United States has different rules about bikes on trains.

I think every bus operator with front bike racks has the same rule: “all day, every day”. But taking your bike on the train is a different story.

In San Francisco, there’re three operators with three sets of rules:

MUNI, a city agency, doesn’t allow bikes on trains, ever. I almost learned about it the hard way. I was returning from downtown on Market Street to my temporary apartment in the Castro District and I took my bike into the MUNI subway. I entered the station without seeing a sign or a staff member that would indicate I couldn’t do this. While walking along the platform, I saw a rules board and noticed no bikes. The trains were not busy, but they’re also not very big. I can see where some people would say, “Oh, I’m new here and I didn’t know”.

But that’s not me. I went upstairs and rode the bike all the way home.

Update May 26, 2011: Streetsblog SF tells us that MUNI will now allow folding bikes on the light rail trains.

BART, a state-controlled transit agency, allows bikes on their trains most of the time. Just not at certain stations, at certain times, and in certain directions. You either memorize these restrictions or carry a brochure.

And BART trains run on broad gauge track making them wider than all other rail transit vehicles in the country. This makes for a lot of space – dedicated space!

Finally, there’s Caltrain, a commuter/regional rail system operated by a joint committee of three transit operators. They seem the least restrictive: every train has a bike car or two, capable of holding about 40, 48, or 96 bikes. “But by the end of 2011, every gallery train set will have two bike cars, allowing for 80 bicycles minimum.” (See last photo.)

In Chicago, the Metra (like Caltrain) and Chicago Transit Authority (CTA, like BART and MUNI) have their own rules that differ from each other and from above.

It’s quite simple to remember the rules of one transit agency, but to be subject to the rules of two or three makes bicycling with rail transit a bit more complicated. The size and design of train cars has a big influence on rule making, but so does politics – the Active Transportation Alliance, né Chicagoland Bicycle Federation, had to lobby the state and the transit agencies here in Chicago to open up their trains to bicycles, and to further liberalize the rules as the agencies became more comfortable.

National or regional planning efforts could ensure that the designs of future or upgraded transit systems follow guidelines that “standardize” the rules of bringing bikes on board. The first step in this direction could be a dialogue between BART and CTA about carrying bicycles onto escalators:

BART did its own study on the “safety issue” years ago and concluded that escalators and stairs were equally safe for cyclists to use in BART stations. (Via Cyclelicious)

The rule banning bicycles from escalators is expected to be lifted this year. The CTA, and other rail operators, could review BART’s study and come to the same conclusion.
