The Bow Curve is a railway branch line in Bow, east London, that connects the Great Eastern Main Line (from Liverpool Street) and the London, Tilbury and Southend line (from Fenchurch Street). The line, 47 chains (0.95 km) in length, connects Stratford on the GEML with Limehouse on the LTSR. It was originally part of the London and Blackwall Railway and had one intermediate station called Bow Road, but today, no regular timetabled services run on this line. It can, however, be used for diversions during engineering work or emergency timetable changes.
