This is a type of game I don't have a lot of experience with, but I enjoyed how much was left up to my imagination. You didn't overwhelm me with trying to show the trains, or feed me random information about who was on the trains or anything like that. I'm wondering how it would feel if you added a simple audio track of humming or whistling to yourself? The kinds of sounds we make to ourselves when we're alone in a quiet room. But jeez, the artwork you went for really feels good in my opinion. Awesome stuff!
