In the first decades of the nineteenth century, there was a considerable increase in coal and iron ore extraction, and of iron smelting, in the general area of
Coatbridge and
Airdrie, and improvements in the efficiency of the process of iron manufacture led to accelerating demand for coal and iron ore, which in turn emphasised the weakness of the means of transport of the heavy materials. In 1771 the
Monkland Canal had opened between the Airdrie pits and Glasgow, and it was followed by the
Forth and Clyde Canal in 1790. In 1826 the
Monkland and Kirkintilloch Railway (M&KR) was opened, conveying the minerals to the canal at
Kirkintilloch for onward transport to Glasgow and Edinburgh. In 1828 the
Ballochney Railway gave access from pits north and east of Airdrie to the M&KR and thence onward to the canal; and in 1831 the Garnkirk and Glasgow Railway was opened, giving a more direct rail connection to Glasgow, but terminating at Townhead canal wharf there. In 1831–2 the
Edinburgh and Dalkeith Railway opened, giving access from pits in the Eskbank and Dalhousie areas to Edinburgh and Leith. Coal and iron deposits were being worked on a small scale in the
Slamannan area, about halfway between Airdrie and
Linlithgow; it was then in Stirlingshire, now in Falkirk District. Seeing the success of the other railways, businessmen interested in the pits promoted a railway to open up their own district, and they formed the
Slamannan Railway Company. It was to run from a junction with the Ballochney Railway near Arbuckle, north-east of Airdrie, to a wharf on the
Union Canal at Causeway End (nowadays spelt Causewayend), from Edinburgh. Thus it would give transport access for pits on the line to Glasgow (over the Ballochney and Monkland and Kirkintilloch lines) and to Edinburgh, by transshipping to the Union Canal at Causewayend. The promoters anticipated a relatively frequent horse-drawn one-coach passenger service between Airdrie and Causewayend. The undulations on the route would allow the horse to ride on the downhill sections: The drawing horse [would be] carried behind the coach in a covered stable waggon. In this way a single Horse would be enabled to perform the journey from Airdrie to Causewayend with a Passenger Carriage once a day, and allowing for spare Horses, five opportunities per day could be given at the expense of maintaining six Horses, with the means of conveying from 130 to 140 Passengers each way daily. ==The company is authorised==
