The Great Western Railway (GWR) 4200 Class is a class of 2-8-0T steam locomotives. They were designed for short-haul coal trips from coal mines to ports in South Wales. The principle role of the class was working the 1000+ ton coal trains up through the Welsh valleys. A job which needed much tractive effort, due to train weights and gradients, and good steaming capabilities. The large boiler was enabled into the design due to the narrow side tanks; these engines would pass numerous water stops along their routes so it was never a worry, because of the class’s heavy water consumption and limited tank capacity they were nicknamed “Water Carts”. The later 5205 Class were very similar. Some were rebuilt in the form of 2-8-2T of the 7200 Class. Five have been preserved, nos 4247, 4248, 4253, 4270 and 4277.
