'Shoc' vans were used for transporting glass or other breakables.  The body is 12" shorter than the frames and is sprung independently, so that if there is a rough shunt when coupled loose there is a delayed shock to the contents of the van.  They are the shock absorbing version of British Rail's diagram 208 standard van, are four wheeled, have an automatic vacuum brake, instanter couplings and hinged doors.  They were painted with white stripes for easy identification.

This particular vehicle was one of 700 built to this diagram.  The XP painted on the side of the vehicle means it could be used on express passenger trains.  B853151 arrived at Quainton March 1994.
