Spotted this in Cambridge aboard the MBTA Red Line. As a frequent reader of your blog, I certainly appreciated it and I thought you might as well!

Transit Maps says:

I feel like there’s a good idea somewhere in this ad, but the execution is a little flat. Shouldn’t “finding help” get the route back on track? The two “warning sign” stations are fine, but using “In Transit” for both of the stations before that is a little lazy in my eyes (not to mention confusing for people using the system if this was a real subway line). The labels could also stand to be a bit bigger as well.
