This map doesn't bring anything new except for knowing when the next train will arrive. It does a poor job at that... the user has to guess when the train will arrive.

This is completely missing the point. No one cares where the train is. They care when it will arrive. Whether it is in a bend, it is waiting or whatever is totally irrelevant.

You need 2 things:

1) A map, whether digital or printed.

2) ETA time.

Why are they spending all this time and energy for something that is useless and unnecessary?
