[spenser]

I was told that it should be on the train, in the car, on the bus, in the taxi, on the tram, in the lift, on the ferry, in the boat, on the plane, on the coach and on the bicycle.

When you are alighting from the above, I was told, we say, getting out of the car/taxi/lift, but getting off the bus/train/tram/ferry/plane/bicycle. And we put/set someone down from a car or let him out at the side. In the case of buses/coaches, we let him off.

In my OALD 2nd edition: get into/out of a train; get on/off a train
But in my OALD 4th/6th edition: get on/off a train

The LANGMAN DICTIONARY OF ENGLISH LANGUAGE AND CULTURE says:
At the beginning of your journey you get on (to) the train and at the end of your journey you get off (it), get out (of it) or alight fml (from it).

And there's similar usage directions in the entry of bus.
