Over this was mounted a short saddle tank for the oil fuel. There was no outer firebox, but the 8 ft × 5 ft (2.438 m × 1.524 m) boiler, pressed to 180 psi (1.2 MPa), contained 289 firetubes in the lower part and a large steam space above. As soon as July 1902, it was redesigned with a smaller firebox and a single burner.
Work subsequently began, and in the process, the railroad converted No. 15 from oil to coal firing. [2] [4] [5] No. 15 participated in its first public Day Out with Thomas events, on the weekend of September 25-27, 1998, but the locomotive was not fired up, and a GE 44-ton switcher moved the train from the opposite end.

When steam locomotives began to be retired from passenger runs, Gold's company, now known as the Vapor Car Heating Company, developed a compact water-tube boiler that could be fitted into the rear of a diesel locomotive's engine room. Known as the Vapor-Clarkson steam generator, it and its competitors (notably the unit built by Elesco) remained ...
The train pack contains a model of 3711 City of Birmingham in World War I khaki livery, three Midland coaches in crimson lake and six World War I figures. In the early 1960s there was a Kitmaster OO scale (1:76) plastic construction kit to build a model of 3440 City of Truro, which was later produced by Airfix and now DAPOL.
In addition to the innovations already adopted for the Modified Hall class, the new class contained several further changes from usual Great Western practice including the use of double chimneys on certain members and a high boiler pressure of 280 psi (1.93 MPa) (although this was later lowered in an attempt to reduce maintenance costs).
A tank locomotive, on the other hand, can simply run around the train (provided there is a siding) and pull it back in the other direction. The crew of a tank engine generally have a better view in the reverse direction than for a tender engine and are protected from the weather. [36]
Assistance was needed by all heavy trains through the Severn Tunnel, which entailed: 3.5 miles (5.6 km) of 1-in-90 down to the middle of the tunnel; then a further 3.5 miles (5.6 km) at 1-in-100 up to Pilning; a short level then 3.5 miles (5.6 km) more at 1-in-100 to Patchway. However, the pilot locomotive usually came off at Pilning.
The Great Western Railway (GWR) 9400 Class is a class of 0-6-0 pannier tank steam locomotive, used for shunting and banking duties. The first ten 9400s were the last steam engines built by the GWR. After nationalisation in 1948, another 200 were built by private contractors for British Railways (BR).
