Angel tube station Angel tube station Angel is a London Underground station in the Angel area of the London Borough of Islington. It is on the Bank branch of the Northern line, between Old Street and King's Cross St. Pancras stations, in Travelcard Zone 1. The station was originally built by the City & South London Railway (C&SLR) and opened on 17 November 1901. The station served as a terminus until the line was extended to Euston on 12 May 1907. The station was rebuilt in 1992 to accommodate the large number of passengers using the station. As a result it has an
North End tube station on 22 June 1907, running through the abandoned station. The uncompleted platforms and lower passageways remain, with access to the tracks. During World War II these were used to store secret archives with access only available from the cabs of passing service trains. During the Cold War a shaft was dug down to the lower passageways and the abandoned station became part of the London Underground's civil defence preparations. As the tunnels were the deepest in the network it was an ideal site. The role of the control centre was to manage the emergency floodgates placed throughout the tube network
