}}'''GWR Corridor Third (TK) 1087 ''' is one of four 1938-built Collett Corridor Third (TK) such coaches on the SVR, along together with [[GWR 1086 Full Third |1086]], [[GWR 1116 Full Third |1116]] and [[GWR 1146 Full Third |1146]]. By the time they were built in 1938, CME Charles Collett had introduced more modern designs to succeed the 'bow-ended' stock. These included large picture windows to replace the external door to every compartment, with access to the coach being via vestibules at each end. Following a GWR policy decision in late 1937, the 1938 design was built to a more restricted loading gauge as used by the LNER and LMS, such vehicles being identified by a yellow disc on the body ends. The 1938 design also reintroduced two extra entry doors on the corridor side.<ref>[[Bibliography#Other References|Harris (1966)]] p. 104.</ref> These particular coaches have 8 compartments each seating 8 passengers, plus a toilet at each end of the coach.  ==Service==They were built at Swindon to diagram number C77 as lot number 1593, with 1087 entering service in March 1938.<ref>[[Bibliography#Other References|Longworth (2018)]] p.55. </ref>
