 to London Waterloo saw a signal in front of him abruptly change from green to red. As required, the driver stopped his train at the next signal post telephone to report to the signalman at Clapham Junction 'A' signal box that his train had passed a red signal. He was advised there was no fault and that he was free to proceed. The driver told the signalman that he intended to make a formal report when he reached Waterloo. As the driver hung up the phone his train was hit from behind by a following train at a speed of 35mph to 40mph (56 km/h to 64 km/h), the late-running 06:14 from Poole

, running under false clear signals.

A second collision, consequent on the first, involved the second, third and fourth coaches of an empty train leaving Clapham Junction (travelling on an adjacent line in the opposite direction) which hit the wreckage of the Poole train, causing derailment and separation of the first carriage of that third train. A fourth train approaching, also under false clear signals at the time, managed to stop about 70 yd (60 m) clear of the rear of the Poole train. This fourth train had lost power as the accident had shorted and discharged the traction current from the third rail.

Investigation

The immediate cause of the crash was incorrect wiring work in which an old wire, incorrectly left in place after rewiring work and still connected at the supply end, created a false feed to a signal relay, thereby causing its related signal to show a green, double yellow or single yellow aspect (depending on the position of traffic around Clapham Junction station) when the track beyond it was occupied when it should have shown red. Indeed, the signal continued to display a single yellow aspect after the accident even though there were now three trains occupying the section beyond it . The larger cause of the accident was the failure by British Rail

 senior management to recognise that the re-signalling of the Clapham Junction area – and indeed the re-signalling of all the lines out of Waterloo, of which this was a part – should have been treated as a major, safety-critical project, controlled throughout by a single, senior, named project manager. Instead the job was left to middle-level technical staff, stressed, poorly supervised by their seniors and poorly supported by their juniors. Staffing levels were inadequate and the staff, dulled by months of voluntary seven-days-a-week work, were carrying out the complete re-signalling of the largest and, on some measures, busiest junction on the whole British rail system.
