Seaton railway station served the village of Seaton, near Workington in Cumberland (now in Cumbria), England. The station was opened by the Cleator and Workington Junction Railway (C&WJR) in 1888 on its new "Northern Extension" from Calva Junction on the northern edge of Workington to the Maryport and Carlisle Railway's Derwent Branch at Linefoot. The C&WJR built this 7-mile-30-chain long (11.9 km) line to connect the C&WJR with Carlisle and beyond. The line was double track from Workington to Seaton, then single to Linefoot Junction.
