The Shenfield to Southend (Victoria) Line is a railway line from Southend-on-Sea to Shenfield in Essex. Almost all trains continue through to London Liverpool Street along the Great Eastern Main Line. It forms Network Rail route EA 1050 from Shenfield Junction.

The line diverges from the Great Eastern Main Line at Shenfield, and is double track throughout.

The line has been electrified at different times using three different systems, all of which used overhead lines to carry the electric current. The first system used was 1500 V d.c., commissioned in 1949[1]. This was to replace an intensive steam service. In the 1960's the line was converted to 6.25 kV, 50 Hz a.c. as part of the decision by the British Transport Commission to adopt 25 kV, 50 Hz a.c. electrification as the standard system rather than 1500 V d.c. electrification. The line did not immediately use 25 kV, due to problems with clearances under bridges. In 1979, the line was converted for a second time to 25 kV, 50 Hz a.c. following more research into the permissible clearances to structures[2].

Passenger services are currently operated by National Express East Anglia. They replaced the previous operator, First Great Eastern, on 1 April 2004, when all the operators in East Anglia were merged into one new franchise. Services are formed using Class 315 or Class 321 electrical multiple units.

The map has been produced using data from Trackmaps[3].
