Castle Green is a proposed railway station in the London Borough of Barking and Dagenham. Plans for a station at the site, initially called Renwick Road, have been in development since at least 2002. The new station was first proposed to be between Barking and Dagenham Dock on the London, Tilbury and Southend line. In 2017 a station was safeguarded on the extension of the Gospel Oak to Barking line between Barking and Barking Riverside. The station would serve the communities of Castle Green, Thames View Estate and new housing developments in the area.
