35192 is a Brake Second compartment (BSK) originally built to carry twenty-four persons in its four compartments, but this was modified for Network South East to carry thirty-two.  It was mounted on B4 bogies and passed for 100 mph running.  It is fitted with vacuum brakes and dual heating, and it has fluorescent compartment lights.  There is a guard's compartment and a luggage area for carrying up to 2½ tons.

Purchased by Quainton in 1989, it has during 2006 had body repairs, repainting and re-upholstery undertaken at the East Somerset Railway.
