Gresley Coach No. 3188's body was built at York in 1934 as a seven compartment coach to diagram 155, lot 488.  It is the only example preserved with entry to compartments via end vestibules.  Delivered to the Southern Scottish section of the LNER, it worked in East Coast express trains.  The frames were built in 1932 by Metro-Cammell, Wednesbury, Birmingham. 

In 1961 it was taken out of passenger traffic and allocated to the Scottish Region Strategic Reserve Emergency Control Train.  This set was disbanded in 1980 and No. 3188 moved to Quainton in 1982 after a period in store at Bicester.  Originally owned by the QRS, it is now owned by a QRS member.
