• 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."
