The station was opened in 1865 by the Metropolitan Railway. Increasing traffic by other companies, including goods traffic, led to the line between King's Cross and Moorgate being widened to four tracks in 1868; the route was called the 'City Widened Lines'. In 1900 the City & South London Railway added the station to its network, under the name Moorgate Street, and the Great Northern & City Railway began serving the station in 1904. In 1975 it was the site of the Moorgate tube crash in which 43 people were killed — the worst accident in the history of the London Underground.
The station has entrances on both Moorgate itself and Moorfields, which runs parallel. While the public entrances from the street give access to all the train services at the station, there are three distinct levels. The Northern line of the Underground uses platforms 7 and 8, which are in a deep-level tube section of the station. Under the Crossrail plans, the western ticket hall of Crossrail's Liverpool Street station will be situated just east of Moorgate station. An interchange will be built, linking Moorgate to the Central line at Liverpool Street.
