The United Kingdom’s worst peacetime rail disaster occurred at London’s Harrow and Wealdstone station on the 8th of October, 1952.
112 people were killed when the City of Glasgow – an express train from Perth, Scotland – crashed into the back of a local passenger train at rush hour. The wreckage covered other rail lines, resulting in a third train – another express – to crash.

In addition to over a hundred deaths, 340 other people were injured, with 88 transported to hospital for treatment.
An investigation found that the driver of the Perth train missed three signals before crashing, but as those involved were killed, the reason for this was never discovered.
