The Murulla rail accident involved the collision of the Sydney-bound Northwest Mail Train with runaway goods wagons near Murrurundi, New South Wales, in the Upper Hunter Valley on 13 September 1926. 26 persons lost their lives. A goods train had become divided and the attempts of the train crew to re-unite the portions resulted in 12 vehicles running away down a steep gradient, and colliding with the approaching mail train. This was the worst accident on the New South Wales rail network until the Granville railway disaster in 1977. == The events == The signal box at Murulla controlled a loop line for trains to pass on a single line railway; there were no other connections at the location. Electric Train Staff operated between Wingen and Murulla and Electric Tablet operated between Murulla and Blandford.〔 Train no 62, southbound goods train comprised a standard goods engine hauling 34 wagons and a brake van were to pass through Murulla on the main line. Another goods train, no 95, working in the opposing direction, had entered the loop line and was waiting for no 62 to pass. No 62 had a length of 951 feet (290 m) and a load of 746 tons (758 t). All vehicles were fitted with Westinghouse air brakes. The train slowed at Murulla signalbox for the exchange of the single line tokens, and as the train staff for the onward section was received, the driver of no 62 put on steam. The shock resulted in the train becoming divided, with the rear twelve vehicles separating from the main train. This was later attributed to the failure of a drawhook. The division of the train was noticed by the driver and both portions of the train were safely brought to a stand. Both portions of the train were verified to be within the clearance points of the loop line, so train no 95 was permitted to depart. The detached portion of no 62 consisted of 12 vehicles, and its length 331 feet with a weight of 264 tons. Handbrakes were applied to these vehicles. It would appear that the train staff in the possession of the engine crew was returned to the instrument in the signal box at this time, and all vehicles were within the confines of the home signals. After a number of attempts to fit a tailrope, the brakevan had been shunted back, foul of the clearance point for the loop line. The two opposing vehicles at the separation were finally hitched with a single wire rope connection, but the airbrake hoses could not be connected. The signalman then requested that the train be brought forward so that it was clear of the clearance point so as to permit the approaching southbound no 8 Mail train to pass through the loop. The guard of no 62 released the handbrakes on the rear portion, leaving it unbraked and the driver went forward to his engine. When he started the train the tailrope broke and the rear portion began to run back down the grade towards Blandford, coming into collision with the approaching mail train just beyond the Up Distant signal. The collision resulted in the death of 26 persons.〔 (Gunn has 27 fatalities.) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Murulla rail accident」の詳細全文を読む スポンサード リンク
