Originally called the Commercial Railway, this railway line ran from the Minories to Blackwall via Stepney, in east London, England. It was authorised by an Act of Parliament entitled "An Act for making a Railway from the Minories to Blackwell, with Branches, to be called "The Commercial Railway"" dated 28th July 1836 in the reign of William IV. A copy of the Act can be read at the Bancroft Road library in Tower Hamlets and the appendix makes fascinating reading for those historians who want to see who owned and who were the tennnants of the properties destroyed.

The company changed its name to the London & Blackwall Railway on completion of an extension to Fenchurch Street railway station.

Although much of the railway was abandoned the original viaducts were reused for the modern Docklands Light Railway service.
