Some commuter rail lines in the U.S. are designed to only cater to commuters. So they may not run any train into downtown at night, or they may stop running well before the shows end at night, so there's no way to use the trains to get back home.

There are a few out of the city until about 11:30 or so. I'd be hanging around for maybe an hour+ then a fairly long train trip to my car.
