The C&WJR was built in the late 1870s, being one of the fruits of the rapid industrialisation of West Cumberland in the second half of the nineteenth century, specifically being born as a reaction to oligopolistic behaviour by the London and North Western and Whitehaven, Cleator and Egremont Railways.

[12] The founding Act of Parliament of June 1878 confirmed the company's agreement with the Furness Railway that the latter would operate the line for one third of the receipts.

The Cumberland iron industry led the charge in the nineteenth century, but became less and less competitive as time passed and local ore became worked out and harder to win, taking the fortunes of the railway with it.

After 1918 the position was reversed, when the litany of step-by-step closures and withdrawals was relieved only by a control cabin and a signalbox being erected at Harrington Junction in 1919.

The Northern Extension had three stations: Seaton, Great Broughton and Linefoot, the last being run jointly with the Maryport and Carlisle Railway (MCR).

From September 1908 this was extended, on Saturdays only, to Great Broughton and Linefoot Junction, making those outposts qualify as stations having had a publicly advertised passenger service.

That experiment failed, as they disappeared from the timetable in December of that year, leaving Seaton as the only Northern extension station with a public passenger service.

[23] The West Cumberland iron and steel industry was heavily dependent on supplies of coke from the Northumberland and Durham coalfields.

Likewise the short chord between Workington Bridge and Cloffocks Junction allowed Durham coke traffic to reach the furnaces via Cockermouth then the C&WJR.

[23] It is therefore no surprise that the line north of Buckhill Colliery closed on 1 September 1921, leaving Seaton station "stranded" on what was effectively a long siding.

An enthusiasts' special passed through Seaton on 5 September 1954, travelling to the then limit of public railway at Buckhill, the only one to traverse the C&WJR using main line passenger stock.
