Right now, it can be difficult to see from inside the train what stop you are at. We should have more signs to the station so people in a train car can see what station they are stopped at.
I think we should have more signs on the wall, saying the name of the station. The pillars with station listings only use two sides--the other two could say what the stop is.
You can print out giant stickers and put them on the pillars. Even if you can't do the wall signs, the pillars should be cheap and easy.
