On several occasions used the Florida to Washington DC Autotrain with the Morgans. (Saves the back side from a very long drive.)
The cars get driven onto the train, and then driven off again, by the train operator's drivers. On one occasion, they couldn't start my friend's 1970 Plus 8, and ran the battery down trying. Had to push the car off the train. Well, they didn't know about the choke. Next time we had a big sign attached to the steering wheel. No problems after that.
Cheers,
