1946
On 10 February 1946, a local passenger train travelling towards Kings Cross hit a set of buffers at Potters Bar station and the derailed carriages fouled the main line. Two express trains travelling in opposite directions then hit the wreckage. Two passengers were killed and the 17 injured were taken to hospital. The driver of the local train was eventually held to blame but a signalman was found to have contributed to the accident by changing a set of points as the train passed over them.
