The Eastern Counties Railway renamed the station "Water Lane" on 1 March 1849, after it became a junction, following the opening of a branch to Lower Edmonton to the north-west.

The Lea Valley line between Copper Mill Junction and Cheshunt was electrified at 25 kV AC in 1969.

[6] Prior to the completion of electrification, passenger services between Cheshunt and London through Angel Road were normally operated by Class 125 diesel multiple units, which had been purpose-built for the line in 1958.

With privatisation, management of the state-owned track and signals passed to Railtrack, which was succeeded by Network Rail in 2004.

[7] Following privatisation in 1994, management of the station was allocated to a business unit before being taken over by West Anglia Great Northern (WAGN) in January 1997, at the time owned by Prism Rail.

[12][13] On 24 January 2019, the DfT announced that Angel Road would officially close on 19 May, with Meridian Water opening on the same day.
