UK Had Cabooses?

There is a brake van in the Thomas story where the S.C.Ruffy wagon gets crushed.
Brake vans were a little like bay window cabooses, with very small bay windows. They served as office space, but the main purpose was to provide braking power on trains that didn't have controllable brakes on all the cars (which was most goods trains until the 70s or 80s). There was a big manual brake wheel in the middle of the car. (regret my only photo is a slide). The ends would have either an open platform or a veranda. The paint scheme (latterly) would be either grey or bauxite (boxcar red).
