deployed to warn the approaching train of the breakdown train's position. The only indication was a warning which was shouted from about 70 metres from the breakdown van by a workman on the line. The driver of the relief special had made several air brake applications on the way down without recharging brake reservoirs. The driver then made an "injudicious" application of the Westinghouse brake and was unable to stop his train. The engine propelled by 226 tons (230 tonnes) of combined weight behind its tender collided with the rear of the breakdown train. The breakdown van, engine and tender were all driven forward 3.5 metres. The engine collided with an "H" wagon that was being re-railed which, in turn, was driven forward into another five goods wagons. Members of the rescue gang, who had been working on the "H" wagon, were crushed beneath the wreckage. An additional breakdown train was sent to the crash site from Toowoomba at 10:00 am. Fifty workers dug frantically in the wreckage to free trapped workers, however six had died due to horrific injuries received in the collision. The driver was found to not have approached the scene of the derailment with "the caution demanded of him", according to the initial departmental inquiry, and that the guard of the breakdown train had failed to adequately protect the rear of it. Humphery, 1918 On 1 June 1918 one man was killed and two women were seriously injured following this collision between a cattle train and a mixed goods on 1 June 1918 at Humphery railway station, 20.2 km from Mundubbera. The collision crushed the guard’s van and telescoped a passenger carriage, fatally injuring one of its occupants. Kuranda, 1918 On 25 November 1918 there were two fatalities and one injury when a 'light engine' ran out of control at the top of the Barron Gorge, 2 km ('a mile and a quarter') from the Kuranda railway station. The engine and tender derailed on a sharp curve and hit a rock wall, the engine falling on its side, causing the boiler to burst and the firebox to be torn open. The driver and fireman, Thomas Patrick Duignan, 27, and Evan William Whiting, 22, were thrown clear but suffered severe injuries and extensive burns. The guard, James Foley, also received serious injuries. The injured men were evacuated by trolley to Redlynch and then taken on a breakdown
