Tube-gauge steam locomotives may appear to be an unlikely possibility, because of the problems of using such a machine in the confines of a tunnel less than Category:Aldwych Branch The Short Streach Of Line Between Holborn And Aldwych Was Closed In 1994.The Line Was Due To be extended to Waterloo but never was.There will be a bit of Aldwych In My Website when added in diameter, but the London Underground had three such vehicles over the years. Two were built by the Hunslet Engine Company in 1899, and the third by Kerr, Stuart and Company in 1922.
Central London Railway[]
Template:Infobox locomotive The Central London Railway obtained two small steam locomotives from the Hunslet Engine Company in 1899, to assist with the task of equipping the tunnels once the civil engineering work of building them had been completed. They were numbered 1 and 2, and were of 0-6-0 wheel arrangement, but only the outer wheels had flanges, which enabled them to negotiate curves of Category:Aldwych Branch The Short Streach Of Line Between Holborn And Aldwych Was Closed In 1994.The Line Was Due To be extended to Waterloo but never was.There will be a bit of Aldwych In My Website when added radius. They appeared to have very large side tanks, but of the Template:Convert/impgal of water carried, only one fifth was used for feeding the boiler, and the rest for condensing the steam. Boiler pressure was Template:Convert/psi, which gave them a tractive effort of Template:Convert/lbf.[1]
Although the cabs were wide, headroom was extremely limited, and consequently they were oil-fired, so that they could be operated by one man rather than two. Fuel tanks holding Template:Convert/impgal of oil were fitted into the bunker, which could also hold 0.75 tons of coal, since the grate was designed so that either fuel could be used. Oil was always used in the tunnels, but coal was often used above ground. Once the railway opened to passengers in July 1900, the locomotives were seldom used in the tunnels, but did occasionally go into them. They were mainly used for shunting coal wagons at Wood Lane power station, which operated until March 1928. However the two locomotives were scrapped in 1923.[1]
City & South London Railway[]

At the same time, the line was extended southwards to Morden station, and the railway bought an 0-4-2 saddle tank from Kerr, Stuart and Company in 1922, to assist with the equipping of the extension. The machine weighed 14 tons, the saddle tank held Template:Convert/impgal of water, and 0.75 tons of coal could be carried. The driving wheels were Category:Aldwych Branch The Short Streach Of Line Between Holborn And Aldwych Was Closed In 1994.The Line Was Due To be extended to Waterloo but never was.There will be a bit of Aldwych In My Website when added in diameter, and it was considerably less powerful than the Central London machines, generating a tractive effort of Template:Convert/lbf. The boiler pressure was Template:Convert/psi, and it was known as the 'Brazil'.[2] Kerr, Stuart built a number of Brazil class locomotives, of which four {{#switch:2ft6in

The locomotive became L34 in 1930, and worked on the extension of the Piccadilly Line to Cockfosters. During this work it was stabled at either Cockfosters or Arnos Grove. It then moved to Drapers Field, Leyton, to work on the Central Line eastern extension. This work was completed in 1949, and the locomotive was then scrapped.[2]
