The story
The North Western Railway was incorporated by the North Western Railway Act 1846 (9 & 10 Vict. c. xcii) on 26 June 1846 to build a railway from Skipton on the Leeds and Bradford Extension Railway to Low Gill on the Lancaster and Carlisle Railway, to carry Yorkshire-to-Scotland rail traffic.
There would be a branch at Clapham, Yorkshire to Lancaster, to make an end-on connection with an associated company.
