All trains serving South Greenford are operated by Great Western Railway.

The Greenford branch of the Great Western Railway (GWR) had been used for regular passenger services since 1904,[2] but the halt at South Greenford did not open until 20 September 1926.

[5] Originally named South Greenford Halt, the suffix was dropped on 5 May 1969.

The normal service from the station runs every day except Sunday until about 22:00 with two trains per hour towards Greenford, where there is a connection with the Central line, and two trains per hour to West Ealing, from where Elizabeth line services run eastbound to London Paddington, Abbey Wood and Shenfield and westbound to Heathrow Airport.

[7] As well as the passenger trains serving South Greenford, the Greenford branch also carries freight traffic, mainly waste and aggregates as well as some empty passenger stock movements.
