This is brilliant. You really need to think how to split the trains signals. I am looking forward for more content. I can imagine building large automation systems with factories, new types of signals, sorting system, very interesting machines. Keep working on this amazing game. I also build something similar but quite a different abstract simulator where the floor of the factory is made of a smart LED that gives instruction to small bots that reads the floor instruction and moves and builds various things. A system without conveyors where all the manufacturing instructions are inside the factory floor.
