4575 PRAIRIE TANK HISTORY
The Great Western Railway (GWR) 4575 Class is a Small Prairie Tank locomotive which was built as a continuation of the 45XX Class. The key difference between the two Classes is the 4575’s increased water capacity of 1,300 gallons, some 300 gallons more than the 45XX and housed in larger tanks which are distinguished by their sloping top at the front end. This increased capacity added 4 tons to the weight of the locos when compared to the 45XXs, with the 4575s tipping the scales at 61 tons. Built at the GWR’s Swindon Works, exactly 100 engines were constructed between 1927 and 1929 and these were numbered 4575–4599 and 5500–5574. These would be the last of the Small Prairies built to the 45XX/4575 design.
Designed for branch line operation, these charming little engines were an everyday feature of the West Country scene and in the early-1950s, a small number were fitted with auto apparatus to work push-pull trains in the South Wales valleys. With the introduction of diesel traction, the first 4575s were withdrawn in the mid-1950s, however this process was drawn out over many years and four survived until December 1964. With many of the Class ending up in Barry Scrapyard after withdrawal, the 4575s became easy targets for preservationists and some 11 examples survive today.
* Class names often change over the lifespan of a locomotive, so this is not necessarily the class name used by the operator in the period modelled.

The locomotive is a 2‑6‑2T steam engine designed by Charles Collett and built by the GWR at Swindon Works between 1927 and 1929. One hundred examples of the 4575 Class were produced, numbered 4575‑4599 and 5500‑5574, and they were intended for branch‑line work in the West Country. The class featured an increased water capacity of 1 300 imperial gallons and a weight of 61 tons.
