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, 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and the other unknown D49 were repaired after the accident but "The Morpeth" sustained substantial damage and was withdrawn and scrapped that same year. = https://www.lner.info/locos/D/d49.php

gollark: He banned me from basically everything he could earlier today, I think because I suggested that (*gasp*) his business ventures aren't entirely altruistic.
gollark: HydroNitrogen considers me toxic or whatever, which I believe is not entirely justified.
gollark: Oh, I suddenly discovered that Hydronitrogen also banned me from speaking on the CC discord. Very thorough.
gollark: Systemd probably shouldn't be kernel panicking anything.
gollark: A good question.
