An idea for another time:
What is Motorail? Normal passenger trains dont carry cars or motorbikes, just passengers and sometimes bicycles. However, special Motorail trains carry cars & motorbikes using car transporters attached to the back or front of the train. These run on a limited number of holiday routes, usually on certain days of the week, usually summer-only.
