Automatic Train Control
The report concluded that an "Automatic Train Control of the Warning type" would have prevented the collision. Although installation had been agreed after the Harrow and Wealdstone rail crash in 1952, priority was being given to main-line routes controlled by semaphore signals. The poor visibility of signals from the steam locomotive, Battle of Britain class No. 34066, was mentioned with a recommendation that they be fitted with wider windscreens.
