had worked for British Rail since he was 16. William Hume was a trainee driver aged 20 and resided in Fintry, Dundee. He had only worked for British Rail for four months. Both were in the cab of the Glasgow to Aberdeen train. The other two immediate fatalities were passengers Dr James Preston, a community health officer aged 65, and Mr Kazimierz Jedrelejezyk, a Polish marine engineer. The fifth death was that of passenger Mrs May Morrison who died in hospital as a result of injuries she had sustained in the crash. Investigation The signalman at Longforgan signal box stated that he put the mechanical starting signal correctly back to Danger behind the Dundee train. Around ten minutes later, the Aberdeen train arrived at his box and drew up to the Home signal, which was then cleared for it. The train continued to move slowly towards the Starting signal but, after a few moments, began to accelerate. It passed the Starting signal which, as far as the signalman could see, was still at Danger. He went down onto the track and saw that the arm of the Starting signal was slightly raised; about 4°. Subsequent investigations showed that it was possible for the arm to have been raised roughly 8°. The guard of the Aberdeen train said that he had looked out of the window of the rear coach at Longforgan as the train picked up speed. He saw the starting signal giving "a poor off" (in other words, somewhere between the "on" and "off" positions), estimating that it was raised 7.4°, but assumed that it had already been put back to Danger after the locomotive had passed it and perhaps had not quite returned to the horizontal position. It is not clear if the guard could have seen the starting signal exactly as the driver would have seen it. The subsequent public inquiry found that the guard was not to blame. Why the driver passed the signal remained a mystery. The inquiry speculated that he may have been looking back towards the signal box, or checking that the train was clear of the level crossing. As he then looked up towards the signal he might have concluded that it had moved since he had last seen it and that it had, therefore, been cleared by the signalman. From a position below the signal and fairly close to it, he
