After that company became a part of the GWR in 1876 he was sent to Swindon and worked under Armstrong and Dean. After his appointment as Locomotive Superintendent in 1902 he developed a series of standard locomotive types with flat-topped Belpaire fireboxes, tapered boilers, long smokeboxes, boiler top feeds, long-lap long-travel valve gear, and many standardised parts such as wheels, cylinders and connecting rods. For express passenger trains he quickly turned out the City class of 4-4-0s, the first taking to the rails in 1903. The following year one of these, 3717 City of Truro, was reputedly the first locomotive in the world to exceed 100 mph. A larger 4-4-0 was produced in 1904 in the form of the County class, but further increases in size demanded more wheels. Experiments had already been made for a 4-6-0 design while Dean was still in charge, and these continued under Churchward; the first 4-6-0, number 100, appeared in 1902 as the initial prototype of what became the Saint class. One locomotive was converted to a 4-4-2 for direct trials against French designs that he tried on the GWR in 1903. These experiments moved the GWR towards using four cylinders and they even tried a 4-6-2, 111 The Great Bear which was the first locomotive of this type in the United Kingdom. Production 4-6-0s appeared in 1905 as the two-cylinder Saint class, and were followed in 1906 by the four-cylinder Star class. A freight version of the Saint, the 2-8-0 2800 class was introduced in 1903. For lighter trains a series of 2-6-0s were turned out in 1911, the 4300 class, which were to become the most numerous GWR tender locomotives. In 1919 this design was enlarged to become the 4700 class 2-8-0s. Churchward's standardisation aims meant that a number of tank locomotives were produced that were based on these tender locomotives. The 2221 class of 1905 were a 4-4-2 tank version of the County class,
