A London Underground train failed to stop at the terminal Moorgate station, crashing and causing the deaths of 43 people.

The London Underground is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire, Essex and Hertfordshire in England.

Moorgate is a central London railway terminus and connected London Underground station on Moorgate in the City of London. Main line railway services for Hertford North, Welwyn Garden City and Stevenage are operated by Great Northern, while the London Underground station is served by the Circle, Hammersmith & City, Metropolitan and Northern lines.

The Moorgate tube crash occurred on 28 February 1975 at 8:46 am on the London Underground's Northern City Line; 43 people died and 74 were injured after a train failed to stop at the line's southern terminus, Moorgate station, and crashed into its end wall. It is considered the worst peacetime accident on the London Underground. No fault was found with the train, and the inquiry by the Department of the Environment concluded that the accident was caused by the actions of Leslie Newson, the 56-year-old driver.
