The Class 42XX was a steam locomotive designed by George Jackson Churchward CBE, Chief Mechanical Engineer (CME) of the Great Western Railway (GWR) from 1902 until 1922.
Due to the increase in mineral traffic in South Wales there was a demand for a powerful locomotive capable of handling very heavy loads. Class 42XX was developed and built especially for moving this heavy freight on short haul trips between the coal mines and ports in South Wales.
The locomotives weighed 82 tons 2 cwt, had a fuel capacity of 4 tons and a water capacity of 1800 Imperial gallons. It was fitted with Stephenson (Piston valve) Gear, a boiler pressure of 200 psi with a tractive effort of 33,170 lbs and two 18″” x 30″” outside cylinders. A total of 60 of these 2-8-0 tank engines were built at the GWR Works in Swindon between 1912 and 1923.
In 1923 a variant, known as 5205 Class was developed, this had larger 19″” x 30″” cylinders, outside steam pipes and an increased tractive effort. Fourteen of the Class were rebuilt as Class 7200 2-8-2T tank locomotives to increase their operating capabilities, these were renumbered as 7240 â 7253 respectively. The total build of both classes was 105, of which 91 were passed to the newly formed British Railways in 1948.
