That was a very fun and unique concept that was executed very well! It was fun to strategize and come up with the best route to take during each loop to maximize my money! I also really like the random generation of the world, it adds more replayability to it! I can totally see this game becoming larger with more trains, types of tracks, maps, obstacles and more! My only suggestion is to have the tracks be less buttons and make it possible to rotate them instead but it isn't a necessity. Overall, great work!
