Newcastle & Carlisle 0-4-0 Locomotives in Great_Britain

Class Details by Steve Llanso of Sweat House Media

Class Comet (Locobase 9057)

Data from Clement Edwin Stretton , The Locomotive Engine and Its Development, a Popular Treatise on the Gradual , Lockwood and Son, 1892, pp 57-58.

Stretton explains that this was the first locomotive for this railway and pulled one of the sections on the line's opening day - 9 March 1835. The boiler and firebox were low-slung, particularly in comparison with the tall stack. The steam dome stood over the leading axle, which was driven by inside cylinders located under the smokebox.

He also claims that Comet and several other similar engines worked "with great efficiency for many years".
