on the Class 769 that was scheduled to run services on the route. Direct Rail Services Direct Rail Services (DRS) has a variety of Class 37s operational and others stored. DRS originally purchased and operated a mix of class 37/0s, 37/4s, 37/5s and 37/6s . Most of the DRS 37s were used on nuclear flask services coming from a host of places including Hunterston, Torness, Heysham, Hartlepool, Sizewell, Bridgwater, Valley, Dungeness, but are now being replaced by Class 68s. These are empty or full FNA wagons often containing spent nuclear fuel. Following a review of traction requirements and delivery of its new Vossloh/Stadler UK Light Class 68 diesels and Stadler UK Dual Class 88 bi-mode locomotives, DRS has stored, withdrawn or sold most of its Class 37 fleet, apart from the 37/4s. In July 2016, 37424 was renumbered 37558 and named Avro Vulcan XH558. DRS Class 37s were hired to power passenger services on the Wherry lines (Norwich to Great Yarmouth/Lowestoft) for Greater Anglia between June 2015 and September 2019, due to a shortage of diesel multiple units, as a result of two serious accidents. Until December 2018 they also hauled passenger services on the Cumbrian Coast line on behalf of Northern Rail (until 2016) and then its successor, Northern. EWS/DB Schenker EWS usually used Class 37s in pairs, for freight workings. Additionally EWS used the Class 37s on railtours or charter hire to train operating companies. For example, in 2005 Arriva Trains Wales used 37/4 haulage on the Rhymney valley line, from a pool of four locomotives, these locomotives being 37405 (EWS livery), 37411 (BR green livery), 37419 (EWS livery) and 37425 (BR Large Logo). 37419 replaced 37408 Loch Rannoch, which was involved in a collision with parked stock at Rhymney sidings, which was suspected to be caused by vandals. 37408 suffered extensive damage and was written off at Toton TMD with its power unit removed and used to revive 37422. Its body was later scrapped at European Metal Recycling, Kingsbury, Warwickshire. By mid-2008, only three EWS Class 37s were still in regular use on the mainline (37401, 417, 422). 37422 was placed in WNTS tactical store pool in September leaving only 37 401 and 417 in traffic. On 16 December, 37 417 suffered serious engine failure and was sent to Eastleigh for storage, resulting in 37401 becoming the only Class 37 to remain in traffic into the new
