Central London / Contractor's Locomotive 0-6-0 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 10132)

Data from "The Steam Locomotives of the Central London Railway," The Locomotive & Railway Carriage & Wagon Review, Vol IV (November 1899), p. 173. See also "London Underground tube-gauge steam locomotives" in Wikipedia at [link], last accessed 11 October 2019.

If one ran an electrified underground at the turn into the 20th Century, what happened when the power went out or workers needed to get to a construction site within the network? One ran these round-shouldered work engines in. They used Holden's oil-firing system in the tunnels "....so as not to emit smoke or fumes whilst in the tunnel, which would of course be dangerous to the men employed." Another aid to fume reduction was an exhaust condenser that filled most of the large tanks with water. In the plein air, they kept up steam by burning coal from a small bunker that held 0.75 long tons (1,680 lb).

Livery was a Midland Railway-like medium red brown with piping.

According to Wikipedia, the two engines actually seldom visited the tunnels and were used primarily for shunting at various depots and at the Wood Lane power station.

Both were scrapped in 1923.


Class unknown (Locobase 20083)

Data from "Contractor's Locomotive," The Engineer, Volume 63 (11 March 1887), p. 191.

This "neat and strong" engine intended, like most Pecketts, for industrial applications such as collieries and ironworks.
