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. It is one of two London Overground lines to form the outer circle of London, linking at Clapham Junction and Highbury and Islington with the Windrush line. 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 of the service was chosen to honour the Mildmay Mission Hospital, which treated patients during the HIV/AIDS crisis in the 1980s. Since 2014 the hospital itself has however been relocated to a new facility more closely served by the Windrush line. A more straightforward connection to the Mildmay area around Newington Green, spanning the core of the route near Canonbury and served by Mildmay Park railway station until 1934, was not cited when the name was selected. The line is blue on the Tube map.
