How about:So, what about a caption for this one?

Very Interesting Ianianmacmillan wrote:The purpose of the break van (as it was originally called) was to keep the couplings tight and prevent them breaking in a sudden snatch. If a coupling did break the the break van could stop or slow the rear portion of the train.
It was also the guard's duty to observe the train to watch for heaters and shifting loads.
Therefore the brakevan should be the rearmost vehicle.
For an unfitted or partially fitted train the van MUST be at the rear.
If the train is fully fitted then up to 15 vehicles may be marshalled behind the brakevan but this was uncommon.
After early 1968, BR did away with brake vans on fully fitted trains - the guard travelling in the rear cab.
However single cab locos (Class 20s, shunters and steam) required a brake van just to provide the guard with a seat.
It was not until the 90s that a brake valve was provided in class 20s to allow the guard to travel in the rearmost cab of a double header.
