Mildmay line

The Mildmay line is the service operated by London Overground on the North London and West London railway lines. It passes through the inner suburbs of London, between Richmond and Clapham Junction in the south-west and Stratford in the east, avoiding central London. Prior to the name being adopted in November 2024, the service was labelled in Transport for London timetables as the Richmond and Clapham Junction to Stratford route.

The name was chosen to honour the Mildmay Mission Hospital, which treated victims of the HIV/AIDS crisis in the 1980s, and the line is blue on the Tube map.
