 * 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The Cattistock and the other D49 were repaired after the accident but The Morpeth sustained substantial damage and was withdrawn and scrapped that same year.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.
