Adds signals to allow stations to couple/uncouple trains automatically.
Mods introducing new content into the game.
Trains are great, but what if they could do even more?
After coupling the train from the back car as well as the train from the front car should go back into automatic. (Takes like 4 lines of code)
Also adding a if #train.locomotives > 0 then train.manual_mode = false end
would be a nice QoL addition
