Upton Park is a London Underground station on the District and Hammersmith and City lines, in Upton Park. It is in Zone 3.
The station was opened by the London, Tilbury and Southend Railway (LTSR) in 1877. District line service began in 1902, and the Hammersmith & City (at that time the Metropolitan line) followed in 1936.

A few years ago I read a book by Mark Mason "Walking the lines" in which he walked the route of the London Underground lines, overground. I will repeat this visiting all 272 stations (some more than once). My route tries to follow the line of the railway as closely as possible, using footpaths and roads, deviations are made to make the walk more "interesting".
