Changes

In 1965, 1116 was one of 9 coaches withdrawn from passenger service to form a test train, based at Swindon, which was used for load testing of diesel locomotives. For this role it received the number 079157, numbers in that range signifying Departmental Coaching stock within the Western Region that did not normally move or had its movements confined to a particular depot or yard. All four of the SVR TKs formed part of the Swindon GWR test train.<ref>[[Bibliography#Other References|Longworth (2013)]] p.172.</ref>.

The entire 9-coach test train was sold into preservation in 1969, with four coaches being bought for the SVR and the others by Didcot. 1116 arrived on 9 December.<ref>SVR Stock Book Ninth Edition</ref> The four acquired by the SVR were restored between 1970 and 1973, and saw service on [[The Severn Valley Railway on the main line#SVR Carriages used on the main line | SVR excursions on the main line]] as well as on the SVR itself. Heritage carriages used on the main line were assigned TOPS numbers, with 1116 being number 99231.<ref>Railway Heritage Register Carriage Survey</ref>
