If they're going to implement this system, they should make a remix of this song (http://www.youtube.com/watch?v=1TaTSIDarZA.) It should play whenever we're inside, enjoying the scenery till our next destination (prolly 5-10 mins if you love cutscenes/scenery.) If you dislike this kind of excitement, do not fret! There will be an option for skipping cut-scenes if your virtual life is so complicated. Also, if they want to make this even more exciting, they should add battles/mini-games while being inside the train.

Summary:
-Remix
-Short/long distances (between 5 and 10 mins) and options for avoiding this if you want instant gratification.
-Cutscenes/amazing scenery
-Mini-games/battles
