Derby 2-8-0 of the Somerset and Dorset Railway

Leaving Minehead for Bishops Lideard and all
stations between. The design used the G9AS boiler from the Midlland compounds, with a Belpaire firebox and Walschaerts valve gear. A leading pony truck was added, to distribute the weight, making it a 2-8-0. The cylinders were mounted high on the frame, and sloped, to avoid fouling platforms. Because of the gradients that the loco would face, Clayton provided two steam brake cylinders on the engine and a further one on the tender. The Derby standard axle boxes were fitted, so the engines were still subject to the hot boxes that were a fact of life on the Midland. As the locomotives were initially too large for some of the turntables, it was envisaged that they would spend half their time travelling in reverse. Consequently, they were fitted with tablet exchanging apparatus on both sides of the locomotive. In addition, the first six were equipped with cab tenders, but these were later removed circa 1920. The 1914-built locomotives were right-hand drive, while the 1925-built were left-hand drive. In all cases the vacuum brake ejector was located on the driver's side of the smokebox. They proved very successful hauling the heavy summer passenger trains over the
Mendip Hills in Sommerset between Bath and Bournmouth, well remembered and well loved
