Class Details by Steve Llanso of Sweat House Media

Class Monkland (Locobase 5649)

Data from [link] (21 July 2003). Jim Howie, author of an extensive history of Lowland Scottish rail history, notes that these were not only the first steam locomotives to run in Scotland, they were the first to be built there as well. (Murdoch & Aitken, a leading manufacturer of blast engines for ironworks, were located on Hill Street in Glasgow.)

The specification called for pulling 60 gross tons at 5 mph. Superintendent Isaac Dodds based his design was based on the Killingsworth colliery type, which featured vertical cylinders driving on the front axle. The axles were coupled and the boiler was multi-tubular, so in some senses this was a state-of-the-art engine. Tappet valves driven by eccentrics metered the steam. Monkland arrived on 10 May 1831 with Kirkintilloch following in September. At the time, rail gauge was 4' 6" -- its broadening to standard gauge came in 1847.
