The story
Monkland and Kirkintilloch Railway
In 1826 the Monkland and Kirkintilloch Railway (M&KR) opened, with the primary purpose of carrying coal from the Monklands collieries, south of Airdrie to Kirkintilloch, from where it could continue to market in Glasgow and Edinburgh over the Forth and Clyde Canal. As a pioneering railway, it adopted a track gauge of 4 ft 6 in, and at first operated as a toll line, allowing independent hauliers to move wagons, using horse traction. It later acquired steam locomotives and ran trains itself. At first it was successful, and when the iron smelting industry became a huge success within the railway's area, it became even more successful.
Ballochney Railway
As coal extraction developed, pits were opened further north and east than the M&KR reached, and the Ballochney Railway was constructed to serve some of them, running from Kipps, near Coatbridge, to pits around Arbuckle and Clarkston, and a quarry. It opened in 1828. The area it reached was on high ground, and two rope-worked inclines were necessary to gain altitude.
Garnkirk and Glasgow Railway
The Garnkirk and Glasgow Railway was opened in 1831 connecting the Monklands directly to Glasgow without the need to transshipment to a canal.
Wishaw and Coltness Railway
The Wishaw and Coltness Railway opened from 1833, connecting iron pits and works further east to Whifflet (then spelt Whifflat) for access to the Coatbridge ironworks.
Slamannan Railway
There was a large area of undeveloped moorland between Airdrie and the banks of the Forth, and a railway was promoted to develop the region. There were optimistic ideas of serving new collieries in the area, as well as the advantage of connecting Monklands to Edinburgh more directly. The Slamannan Railway opened in 1840 between Arbuckle and Causewayend, a wharf on the Union Canal; it had a rope worked incline down to the wharf. Onward transport to Edinburgh involved transshipment to canal barges.
