Leicester & Swannington 0-6-0 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class Atlas (Locobase 20328)

Data from James Dredge (ed.), "Section V Historical Locomotives and Rolling Stock -- No 104, 'The Atlas'", in A Record of the Transportation Exhibits at the World's Columbian Exposition (New York: John Wiley & Sons, 1894), p. 344. Works number was 58 in 1834.

Dredge reported that when this locomotive, the first six-coupled Stephenson engine, was delivered in February 1834 it was "the largest, heaviest, and most powerful locomotive running." Low cylinders drove wheels that had the cranks mounted outside of the hubs.


Class Vulcan (Locobase 16088)

Data from Arthur E Kyffin, "Some Vulcan Foundry Engines", The Railway Engineer, Volume 17, No 9 (September 1896), p. 259 and "The Vulcan, No 10" drawing archived at Vulcan Foundry website, [link], last accessed 26 July 2015. Works number was 10 in

For its time, this design seems remarkably advanced. The Stephenson type boiler has a huge drum for a "dome" just behind the stack, the inside cylinders drive horizontally, and the firebox is flush with the top of the boiler.
