The Beckton Corridor was once the railway line that travelled from Stratford to Beckton to serve the Beckton Gas Works, it was bombed during the Blitz and reopened later for freight only but closed in December 1970.
At its peak, Beckton supplied gas to over four million Londoners, as well as manufacturing by-products such as creosote, fertilisers, inks and dyes. It was not until the switch to natural gas in the 1960s that the works were scaled down. The neighbouring marshland was formerly occupied by hundreds of garden allotments and was also the site of a prisoner of war camp during the Second World War.
This spot is a great little wildlife area, perhaps you will see a terrapin while you are here, look out for Terrapin Island.
