ARail -- A choo-choo train game

Do you remember the toy trains in our childhood? It brought us a lot of fun.
I got this train theme game on iPhone.

The goal of this game is to guide the train into the station which has the same color.
It's easy to play : tap the screen to change the rail's direction.
Each entrance has two or more routes to the station, your task is to make the rail planning, avoid the train crash or rear-end.
How many scores can you get? I got 105.
