Under the Whyte notation for the classification of steam locomotives, 4-2-2 represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle, and two trailing wheels on one axle.
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.
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 is a class of four 2-2-2 steam locomotives designed in 1855.
The Glasgow and South Western Railway (GSWR) 2 class is 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) 40 class is a class of ten 2-2-2 steam locomotives designed in 1860, a development of the 2 class intended for express passenger duties.
The Glasgow and South Western Railway (GSWR) 45 class is 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) 99 class is a class of four 0-2-2-0 steam locomotives designed in 1855.
The Glasgow and South Western Railway (GSWR) 105 class is a class of four 0-4-2 steam locomotives designed in 1856.
The Glasgow and South Western Railway (GSWR) 9 class is 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 is 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 is 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 is 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 is 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 is 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 is 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 NER B and B1 Classes were two classes of 0-6-2 tank locomotives designed by Thomas William Worsdell for heavy freight and mineral on the North Eastern Railway, introduced in 1886. They were tank engine versions of the NER C1 Class 0-6-0, using both simple expansion and also the von Borries configuration for two-cylinder compound locomotives. Both types were later rebuilt using superheated steam and the compounds were also rebuilt as simple expansion locomotives, and eventually formed a single class. Many of the superheated locomotives were also later returned to saturated steam as their original boilers wore out. As a result the classes have had a very complex mechanical history.
