First in a new class of locomotives and originally numbered D6700, this loco was delivered new to Stratford in December 1960 where it remained for seven years working services out of Liverpool St. to Norwich and Kings Lynn. Moved to Derby Research Centre in early ’68 and onto Haymarket on loan for push-pull trials on the Edinburgh – Glasgow route. These trials proved unsuccessful and the loco soon returned to Stratford two months later. Over the next sixteen years it had a tour of most major Eastern region depots taking in March, Thornaby (three times), Gateshead (twice), Tinsley, Healey Mills, Stratford (again), and Immingham (twice) being renumbered in the TOPS system to 37119 during this period in February 1974. With CP7 bogies fitted it was renumbered again in May ‘88 to 37350 and not long after sent back to Stratford. A change of region came about when “Sectorisation” of the railways took place and 37350 was allocated to the Petroleum Sector at Cardiff Canton in November ’88. Problems with sprinters in mid ’89 meant 350 was temporarily loaned to the Provincial Sector working passenger train primarily from Cardiff to Weymouth and Manchester. Once services returned to normal 350 would be back with the Petroleum Sector. Sent to Immingham in October ’92 it remained there for a few months before going into store in April 1993. Reinstated to service in November ’93 and named “NRM National Railway Museum” at York on 13th November 1998 and allocated to Toton but didn’t last long before once again going into store at Thornaby. Privatisation of the railways allowed for 350 to be given by EWS to the NRM York. The loco has since been returned to its D6700 condition and can be found at the NRM York or out on loan to various preserved railways.
Added to the Cardiff Canton ETH 37 pool for a few months 37350 had a diagram of its own. Seen here at Weston Super Mare with the 11:20 Bristol TM to Taunton on 29th May 1989.
