Sure, but you were comparing it to San Francisco.

I forgot to add SF to that list. I admit most of time was on the BART and not on CalTrain.

There is no way SF compares with New York, London or Tokyo.

This is the BART map: http://sf.metblogs.com/archives/images/2008/02/big_bart_map....

There is no contest.

I like how the labels obscure the fact that BART just cuts a line through the city of San Francisco. Also funny is how the legend at the bottom of the map blots out the parts of south bay where everything actually is.

Note also that the Chicago map is just a route map, and bears little relation to the geography of Chicago.
