Milton rail crash


The Milton rail crash was a crash in 1955, at Milton, Berkshire. A passenger train took a crossover too fast and derailed. Eleven were killed, and 157 were injured.

Overview

The crash occurred at about 13:15 on Sunday 20 November 1955, at Milton, between and on the line from on the Western Region of British Railways. The train involved was the 08:30 excursion train from, South Wales, to Paddington station, consisting of ten coaches hauled by Britannia Pacific no. 70026 Polar Star. The train failed to slow down for a low speed crossover.
The engine and several carriages rolled down an embankment, which exacerbated the severity of the accident.

Contributing factors

Because the track involved had been formerly operated by the Great Western Railway, the signals were on the right hand side, but the train was hauled by one of the new British Railways Standard Class 7 locomotives, which had its driving position on the left hand side. This incompatibility hampered the driver's view of the signals.
There was a berth track circuit approaching the crossover, but it was much longer than the train, which made it hard for the signalman to estimate the speed of the train.

Aftermath

The signals were later modified to prevent a driver seeing a proceed signal for the crossover too soon. This is known as Approach Release.
Handrails on the smoke deflectors also obscured the drivers' view, and these were later removed and replaced with hand holds on all the "Britannia" class locomotives that ran on the Western Region.
