    Churchward 4200 Class 2-8-0T
    The GWR took over operations and then absorbed the various South Wales based railways from the late 1800s, operational practice on most was defined by moving heavy coal trains on sharp, steep and undulating tracks. Thus many of these railways - especially the dominant Taff Vale Railway - specified and used an 0-6-2T, which gave maximum tractive effort whilst riding well on the undulating track.
    With coal trains increasing in size and scale, the GWR needed to develop a more powerful locomotive to meet these requirements, on what were relatively short haul routes. Thus in 1906, Chief Engineer G.J. Churchward took the basic design of his GWR 2800 Class, and adapted it. After proposing a 2-8-2T design, Churchward developed the UK's first 2-8-0 Tank engine, through concerns that the longer frames required for a 2-8-2T would restrict operation in the South Wales Valleys.
    Churchward upgraded the power of the design, modifying the frames to hold a GWR standard No.4 boiler over the 2800 Class standard No.1. The flanges of the second and third driving wheels were made thinner, and the coupling rods between the third and fourth sets of driving wheels used spherical joints, all to create side play and hence flexibility in operations. The prototype No.4201 was out shipped from Swindon Works in 1910 under Lot No.142, with a straight back bunker capable of containing three tonnes of coal. In 14 months of testing, it easily proved itself capable of negotiating curves down to 2 chains (130 ft; 40 m) in radius.

    Operations
    Put into production in 1912 under Lot No.187, the first locomotives were Nos. 4202 - 4221, which had both top feed boilers and curved upper bodies to their coal bunkers to provide 3.5 tonnes of coal carrying capacity.[2] Working 1000+ ton coal trains through the South Wales Valleys, from coal mines to ports, the large boilers and restricted loading gauge resulted in narrow side tanks. Although passing numerous water stops along their routes, because of the class’s heavy water consumption and limited tank capacity, they were nicknamed “Water Carts”. 105 4200s were built between 1910 and 1923.[1][2]
