Bethnal Green is a London Overground station, on the Lea Valley Lines 1.8 km down-line from London Liverpool Street; the next station down-line is either Hackney Downs (for services to and from Chingford) or Cambridge Heath (for services to and from Cheshunt and Enfield Town). It is in Travelcard zone 2.
The station was opened in 1872 and was formerly called Bethnal Green Junction until 1946. It is some distance from Bethnal Green tube station on the London Underground's Central line

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".
