Lovely little game. Harder than it looks.
It really needs an S-bend piece of rail though. If your lines are off by 1 tile, connecting them is a pain.
Also, I think "chill mode" should let you build stations where you want to - like a creative mode, and also to toggle train collisions on and off whenever you want to. Something like a creative mode.
Really enjoyed my time playing. I wish we could just spawn more stations and trains until the map was full and the railroad is a spider web of incomprehensible complexity. So yeah, add an endless mode :D
Here's my railway. It might not be the most optimal, but at least the trains don't crash and I made it to the end! Had the worst station spawns - they always cut my railway in half! :(
