The Monkland Railways was a railway company formed in 1848 by the merger of three "coal railways" that had been built to serve coal and iron pits around Airdrie in Central Scotland, and connect them to canals for onward transport of the minerals. The newly formed company had a network stretching from Kirkintilloch to Causewayend, near Linlithgow. These coal railways had had mixed fortunes; the discovery of blackband ironstone and the development of the iron smelting industry around Coatbridge had led to phenomenal success, but hoped-for mineral discoveries in the moorland around Slamannan had been disappointing. The pioneering nature of the railways left them with a legacy of obsolete track and locomotives, and new, more modern, railways were being built around them.
