Thanks for the nice comment and I am glad you enjoyed the game! I would like to expand more on this, but currently have a few other projects underway so my time is pretty limited.
If I were to expand upon it, was there anything you would’ve liked to see or have included? I have some thoughts on more structures, like a windmill that activates the tile in front of it periodically. Or research buildings that upgrade the strength/power of the train cars.
