Names and numbers

Accidents and incidents

• On 3 January 1931, locomotive No. 2758 Northumberland was hauling a passenger train that was derailed at Carlisle, Cumberland due to excessive speed through a curve. Three people were killed.^[1]
• On August 16, 1952, the single D class locomotive No. 62768 The Morpeth was involved in a collision between a light engine and a passenger train at Dragon Junction near Starbeck. The other two locomotives involved were also Ex-LNER D49's. No.62758 The Cattistock and the other D49 were repaired after the accident but The Morpeth sustained substantial damage and was withdrawn and scrapped that same year. The Cattistock’s tender was damaged, so it and The Morpeth’s undamaged tender were swapped.^[2]
• In July 1958, locomotive No. 62703 Hertfordshire ran into the turntable pit at Bridlington, Yorkshire and rolled onto its side.^[3]
