Very nicely done with many options

I just wanted to briefly times daily in any train simulation to see how this is so, to control a train. I did not think that I so find a great app, moreover free.
Not only that, you can move from the perspective of a train driver, a vehicle, it also has several routes and several vehicles to choose from. And then you can select another super-drawn 3D views: from the front, from the outside, from the platform ... I'm excited!
The only (small) drawback: long load times (at least on my Kindle Fire HD) and high battery consumption.
