This is a neat little game. I managed 19,874 on my second run, and stopped at several of the yellow station spots. The controls are simple and easy to understand, though it does take a bit of practice to figure out how to best use them with just being able to select the 2 gears, idle, and break. The sound when close to derailing is a nice touch.
After I got the timeout popup, the train continued moving and I could still control it.
The music is decent, but does feel a bit repetitive after a while.
You are certainly making good progress and heading in the right direction.
