My Railroad: trains and rails

Update review: So... I just updated the app and the quicker trains are a big improvement! Thank you! It's a bit like a puzzle and that what makes it so much fun. I like this game. With the changes I am bumping up my stars to five. Original review: It is fun and a challenge to get the trains to the correct stations and quite often they crash. Frustrating when a train nearly at the station and here come one out of the station. There is nothing to do but watch them crash. In this game crashing trains aren't an issue, just have to get the wreck cleaned up which can also be a challenge with the wrecker train being on the tracks. The reason I did not give the game more stars is because it is blatantly obvious that I need to watch ads or spend money to really enjoy the game. I understand that the developer needs to make money. Ease up on it a bit; else you may see in the data that people will simply stop playing because of this blatancy. I'm nearly there. Finally, what is repairing the train all about? I don't get it.

Game have a very good potential. Love the graphic, I think controls not yet there, but in general good game.
