The Glasgow and South Western Railway (GSWR) 99 class was a class of four 0-2-2-0 steam locomotives designed in 1855.
Four examples of class designed by Patrick Stirling were built for the GSWR by R and W Hawthorn between April and August 1855. [1] Little is known about the class which is variously described as having a "dummy crank" [2] or a "crank axle." [1]
The design was apparently unsuccessful, and all were withdrawn by James Stirling in 1866 and 1867.
Under the Whyte notation for the classification of steam locomotives, 0-2-4 represents the wheel arrangement of no leading wheels, two powered driving wheels on one axle, and four trailing wheels on two axles.
James Stirling (1835–1917) was a Scottish mechanical engineer. He was Locomotive Superintendent of the Glasgow and South Western Railway and later the South Eastern Railway. Stirling was born on 2 October 1835, a son of Robert Stirling, rector of Galston, East Ayrshire.
Under the Whyte notation for the classification of steam locomotives, 2-2-2-0 usually represents the wheel arrangement of two leading wheels on one axle, four powered but uncoupled driving wheels on two axles, and no trailing wheels, but can also be used to represent two sets of leading wheels two driving wheels, and no trailing wheels. Some authorities place brackets around the duplicated but uncoupled wheels, creating a notation 2-(2-2)-0, or (2-2)-2-0, as a means of differentiating between them. Others simply refer to the locomotives 2-2-2-0.
The London and North Western Railway (LNWR) DX Goods class was a class of 0-6-0 steam locomotive, designed by John Ramsbottom for freight duties. 943 were constructed, making them the largest single class of steam locomotives built in the United Kingdom. Despite this, none were preserved.
The Glasgow and South Western Railway (GSWR) 187 class were a class of 0-4-2 steam locomotives designed for mixed traffic duties, by James Stirling in 1870. They formed a model for large numbers of similar 0-4-2 mixed traffic locomotives subsequently built on GSWR and other British railways.
The Glasgow and South Western Railway (GSWR) 956 class was a class of four 2-2-2 steam locomotives designed in 1855.
The Glasgow and South Western Railway (GSWR) 2 class was a class of thirteen 2-2-2 steam locomotives designed in 1857 by Patrick Stirling and intended for express passenger duties.
The Glasgow and South Western Railway (GSWR) 45 class was a class of eleven 2-2-2 steam locomotives designed in 1865, an enlarged version of his 40 class intended for express passenger duties.
The Glasgow and South Western Railway (GSWR) 105 class was a class of four 0-4-2 steam locomotives designed in 1856.
The Glasgow and South Western Railway (GSWR) 9 class was a class of seven 0-4-2 steam locomotives designed in 1857, as an enlarged version of the 105 class.
The Glasgow and South Western Railway (GSWR) 34 class was a class of ten 0-4-2 steam locomotives designed in 1858.
The Glasgow and South Western Railway (GSWR) 23 class is a class of twenty 0-4-2 steam locomotives designed in 1860. They were by Patrick Stirling's fourth 0-4-2 design for the railway.
The Glasgow and South Western Railway (GSWR) 131 class was a class of ten 0-4-2 steam locomotives designed in 1864. They were by Patrick Stirling's fifth 0-4-2 design for the railway.
The Glasgow and South Western Railway (GSWR) 52 class was a class of six 0-4-0 steam goods locomotives designed in 1864, by Patrick Stirling. The design was later continued by a similar design by his brother James Stirling.
The Glasgow and South Western Railway (GSWR) 46 class was a class of six 0-6-0 steam locomotives designed in 1862. They were Patrick Stirling’s second 0-6-0 design for the railway.
The Glasgow and South Western Railway (GSWR) 58 class was a class of six 0-6-0 steam locomotives designed in 1862. They were Patrick Stirling’s third 0-6-0 design for the railway.
The Glasgow and South Western Railway (GSWR) 103 class was a class of two 0-6-0 steam locomotives designed in 1855. They were Patrick Stirling's first 0-6-0 design for the railway.
The Glasgow and South Western Railway (GSWR) 141 class was a class of ten 0-4-2 steam locomotives designed in 1866. They were by Patrick Stirling's sixth 0-4-2 design for the railway.
The Glasgow and South Western Railway (GSWR) 6 class were a class of twenty-two 4-4-0 steam locomotives built in 1873. They were designed by James Stirling to handle express passenger trains taken over from the Midland Railway at Carlisle between there and Glasgow on the newly opened Glasgow and Kilmarnock Joint Railway.
The Glasgow and South Western Railway (GSWR) 8 class were a class of sixteen 2-4-0 steam locomotives built between 1868 and 1870.
