In March 1847, the Blackburn, Darwen and Bolton Railway and the Blackburn, Clitheroe and North Western Junction Railway agreed to amalgamate, becoming the Bolton, Blackburn, Clitheroe and West Yorkshire Railway; the necessary Act received Royal Assent on 9 July 1847. The name was shortened to the Blackburn Railway by a further Act of 24 July 1851.
The Blackburn Railway opened from Bolton to Blackburn on August 12th 1848, and from Blackburn to Chatburn on June 22nd, 1850. [1]
