- London Overground Romford-Upminster Line is a Transport for London operated Overground line in London, England. Running between Romford and Upminster, the line is single-track throughout, electrified at 25 kV AC, has a loading gauge of W6, and a maximum speed of 30 miles per hour (48 km/h).
The line was originally built as a branch of the London, Tilbury and Southend Railway (LT&SR) and opened on 7 June 1893 providing the LT&SR with a link to the Great Eastern Railway at Romford and a small goods yard where the branch joins the Great Eastern Main Line. At Romford the branch had a separate station entrance in a three-storey building opposite the Great Eastern station entrance and a cast-iron footbridge was constructed over South Street which opened when a LT&SR train was due. When in April 1934 the LT&SR building ceased use as a station and the ground floor was rented as a shop, the then London and North Eastern Railway took control of the whole station.
On 5 February 2012, the route was retained by Abellio Greater Anglia.
On 31 May 2015, the route passed to London Overground and was included in the sale from Abellio Greater Anglia's Ilford depot.
On 22 Oct 2015, two Class 321s were temporarily introduced.
On 3 March 2020, brand new Class 710/1 Aventras were introduced.
In April 2020, the Class 317/7 and 8 were withdrawn and replaced by brand new Class 710/1 Aventras.
On 5 October 2020, the Class 315 was withdrawn and the line was converted into a full Class 710 Aventra operation.
