Interesting, never knew it worked like that, and come to think of it I have seen photos of trains with more than one buffer car.
I'm not sure how long the train must be to require this buffer car.
I don't think there is a certain length but what they are carrying.

There is usually one at the end of unit tanker trains also for the same reason, in case a train rearends the other.
