Originally built as an oil-burning locomotive 'on Holden's system'[2][a], it had an unusual boiler containing a firebox constructed as an arched chamber made from fire-bricks, opening to the firetubes in front, and with two oil-burning nozzles at the back. 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. It was given a Lentz boiler with a cylindrical corrugated firebox inside the barrel in 1903. The saddle tank for fuel was removed and oil stored at the rear end of the side tanks. In 1905, the locomotive was rebuilt as a coal burner, with the cab backplate replaced by a bunker.
It was intended for light passenger service on the Wrington Vale Light Railway near Bristol. However, due to technical issues associated with the design, the locomotive never saw the intended service. It remained at Swindon Works, used as a works shunter. No further engines were built to this design, and the locomotive was withdrawn and scrapped in 1911.[1][2]
Despite it being a unique, obscure and short-lived experimental loco, Hornby have been producing a 00 scale model of No. 101 since 1978, in many prototypical and non-prototypical guises. It is currently sold as part of the Railroad range.[4] Hornby have sometimes inaccurately ascribed the whole design to Holden, instead of just the oil-burning mechanism.[5]
^James Holden left the GWR in 1885 for the GER, where he developed oil burning technology for steam locomotives, being granted a patent for it[3] in 1899.
