North London Line City Branch

The City Branch was a short spur of the North London Line allowing direct access from the east-west main route of the North London Railway to the terminus at Broad Street in the City of London.

The North London Railway (NLR) was founded in 1850 with the intention of operating a network of railway lines throughout north London that connected to the East India and West India Docks. The company's main headquarters was at Bow, and from there a connection to the London and Blackwall Railway's route allowed the NLR's trains access to a terminus in the City of London, in this case Fenchurch Street. However, this meant that, in order to reach the City, the NLR's trains had to take a fairly circuitous route, and so the company decided to build its own central terminus.

In 1861, the North London Railway Act was passed giving permission to the NLR to build an extension from its main line through Hackney to a site at Old Broad Street. The majority of the route was built on a viaduct from Dalston, with a triangular junction allowing access to the main line in both directions. The extension had four new stations:

Passenger services along the Kingsland Viaduct to Broad Street began in November 1865. Initially, the branch had three running lines; a fourth line was added in 1874. The route was electrified in 1916 using the 600V DC third and fourth rail system, with the purchase of new electric rolling stock. However, only the western five platforms at Broad Street were electrified.

Both Haggerston and Shoreditch stations, as well as the rest of the branch, received heavy damage in the Second World War, and were closed in 1940, leaving Dalston Junction as the only intermediate station between Broad Street and the main line. At this time, passenger numbers on the branch were declining. The eastern route to Poplar was closed in 1944, while services from the rest of London declined. The route was earmarked for closure under the Beeching Axe in 1963, but remained open due to local pressure. However, the opening of other routes led to further services being withdrawn until it was decided in 1985 that the route would be mothballed. By then Dalston Kingsland had opened to serve the Dalston area, and both Dalston Junction and Broad Street were closed.
