LOL from Chicago. Or more accurately I'm told "mostly west of the mississippi" routes have the nice double decker cars and "mostly east of the mississippi" routes have the dumpy single height worn out cars.

I also heard they're starting to use new cars out east that are nice but I've never seen one outside fawning journalist articles (they may be nice, they may not, but coverage is overwhelmingly positive). Maybe next time I take an overnight to NYC I'll get to try a new model train car.
