Signals Mod
Signals Mod 1.12.2, 1.10.2 adds Signals to the game, which behave similar to OpenTTD signaling (which is based on how train signals in real life behave). Apart from Signals this mod contains a routing system, where carts can be configured to go to a certain station and the routing will do the rest (decide the best route and operate junctions).
