}}LNER Kitchen Composite (RC) 7960 was designed by LNER CME Sir Nigel Gresley and built at Doncasterin 1936 to LNER Diagram 187.<refname=Longworth>[[Bibliography#Other References|Longworth (Or built at York, see sources below2018)]] p.266.</ref> in 1936. It was originally equipped with an anthracite-electric kitchen to serve meals into separate First and Third class saloons seating 12 and 18 respectively.

7960 was renumbered as 9162 as part of the LNER's 1943 re-numbering scheme. On Nationalisation in 19461947, BR initially allocated an E prefix to indicate its LNER origin, with a further re-numbering to SC9162E after 1951.<ref>[[Bibliography#Other References|Longworth (2018)]] p.175. </ref> It remained in use in the former GNS area of the LNER until the 1960s. Its regular diagram was Aberdeen to Inverness, northbound serving breakfast, dinner on return.

===Departmental service===Following withdrawal from passenger service it was converted to a Mess Coach for Scottish Region track workers, as departmental number DE 321021from December 1963. <ref name=Longworth/> The third class saloon was most altered to three sleeping compartments with a side corridor, and the former first class to a messroom complete with coal burning stove. Surprisingly the kitchen remained largely untouched although at some stage in its life the anthracite-electric cooker had been replaced with gas.
