“Sir,—I beg to inform you of a serious accident, attended by severe injury, if not loss of life, which occured to-day to the 8 o’clock a.m. train from Wakefield, on the Great Northern railway, near Doncaster, by which I was a passenger. As the train approached Doncaster, about 9 o’clock, the passengers were suddenly alarmed by the vehement oscillation of the carriages. In a few seconds the engine had run off the line, dragging the greater part of the train with it across the opposite line of rails. By this time the concussion had become so vehement that the grappling chains connecting the engine, tender, and first carriage with the rest of the train providentially snapped. This circumstance saved the lives of many. But the engine, tender, and first carriage were hurled over the embankment, all three being together overturned, and the latter (a second-class one) nearly crushed. The stoker was severely injured on the head, and his recovery is more than doubtful; the engine driver contrived to leap off in time to save himself with a few bruises. The shrieks of the passengers in the overturned carriage (three women and five men) were fearful; and for some time their extrication was impossible. One middle-aged woman had her thigh broken, another her arm fractured. One old man had one, if not two of his ribs broken. The passengers in the other carriages, in one of which I was travelling, were less seriously injured, though sufficiently so to talk about compensation, instead of assisting in earnest those with broken limbs. The line of rails was torn up for a considerable distance. Owing to the telegraph being out of gear, some delay in communicating with Doncaster was experienced. A surgeon and various hands at length arrived with a special train for the injured passengers, who, after long delay, were removed to Doncaster. I, of course, as a medical man, rendered what assistance I could. Those worst injured were conveyed to the Railway Arms, the recovery of more than one being doubted by myself. At length a fresh train started from Doncaster, and we reached London nearly two hours after due. The carelessness of the Company will, I hope, be the subject of your severest animadversion. The accident was caused by the tire of one of the right wheels of the engine having flown off; and it is clear that the engine was not in a condition to ply between the stations of the Great Northern railway. I have no objection to your use of my name if you think fit to publish it. Your obedient servant, Thomas Waddington, M.D., of Wakefield. Morley’s Hotel, Charing Cross, March 26.
