ah, thank you for the info

The other one controls the locomotives, this one controls the tanker and aircraft linked above. Like using a train as a mobile base.

It's a personal thing really. I commandeer the tanker remotely from the train to do trade runs and the aircraft to relay radio signals to the tanker or move myself around.

What is the difference between this and the other command carriage?
