Great game: some suggestions
This is a great game but I would like to see more scenarios. For example, when I tap subway line 7, I would like to see more come up, like "express service" where you only stop at certain stops, or "special service" where you drive the opposite track due to track construction or something like that. Also add an interior view of the train instead of not seeing the inside of the train. Also add people to the stations and trains.
