There were two interlinked railways on the south shore of the Solway Firth.

The Newcastle & Carlisle Railway (N&CR) was an English railway company formed in 1825 that built a line from Newcastle upon Tyne on Britain's east coast, to Carlisle, on the west coast. The railway began operating mineral trains in 1834 between Blaydon and Hexham, and passengers were carried for the first time the following year. The rest of the line opened in stages, completing a through route between Carlisle and Gateshead, south of the River Tyne in 1837. The directors repeatedly changed their intentions for the route at the eastern end of the line, but finally a line was opened from Scotswood to a Newcastle terminal in 1839. That line was extended twice, reaching the new Newcastle Central Station in 1851.
