The Hawes Junction rail crash occurred at 5.49 am on 24 December 1910, just north of the Lunds viaduct between Hawes Junction (now known as Garsdale station) and Aisgill on the Midland Railway's Settle and Carlisle main line in the North Riding of Yorkshire (now North Yorkshire), England. It was caused when a busy signalman, Alfred Sutton, forgot about a pair of light engines waiting at his down (northbound) starting signal to return to their shed at Carlisle. They were still waiting there when the signalman set the road for the down Scotch express. When the signal cleared, the light engines set off in front of the express into the same block section. Since the light engines were travelling at low speed from a stand at Hawes Junction, and the following express was travelling at high speed, a collision was inevitable. The express caught the light engines just after Moorcock Tunnel near Aisgill summit in Mallerstang and was almost wholly derailed. Casualties were made worse by the telescoping (over-riding) of the timber-bodied coaches, and by fire which broke out in the coaches, fed by the gas for the coaches' lights leaking from ruptured pipes. Twelve people lost their lives as a result of this accident, some of whom were trapped in the wreckage and were burned to death. A song about the accident was written and sung by Dave Goulder. The accident Hawes Junction station was approximately south of Ais Gill summit, the highest point on the steeply graded Settle and Carlisle line. The Midland Railway, who owned and operated the line, had a policy of using small engines only, and many trains (both northbound and southbound) required assistance from pilot engines to climb the "big hump" to Ais Gill summit. At Ais Gill summit the pilot engines were uncoupled and ran on the up (southbound) line to Hawes Junction, where there was a turntable accessed from the up main line via a trailing slip or from the back platform line (a loop line alongside the up main line which served the branch line to Hawes). Having been turned, light engines were usually coupled together to return to their depots (usually Leeds to the south or Carlisle to the north). In the hour preceding the accident, signalman Sutton at Hawes Junction had to deal with nine light engines and a heavy load of scheduled traffic and some unscheduled special trains
