Paris a Versailles 2-2-2 Locomotives in France
Class Details by Steve Llanso of Sweat House Media
Class La Rapide (Locobase 6047)
Data from [
] (visited 29 May 2004) and from Felix Mathias, Etudes sur Machines Locomotives de Sharp et Roberts Comparees a Celles d'Autres Constructeurs ...(Paris, Librairie Scientifique-Industrielle de L. Mathias, 1844).
The accompanying illustration shows a typical Sharpie with the bowed frame, inside cylinders, tall stack, dome well forward, and low, round-topped firebox.
Class l'Artesienne (Locobase 11353)
Data from website celebrating these two pioneers in locomotive construction in Alsace - [], last accessed 13 June 2010.
Following up on its success with the Alsatian Ville de Thann, this small firm supplied two locomotives -- Strasbourg and Bittschwiller -- for the 134-km line between Basle and Strasbourg. Note the relatively tall drivers.
The B a S modified both engines to the 2-4-0 layout used by the Ville de Thann. Its drivers now measured 1,510 mm, cylinders grew to 360 x 520 mm, boiler pressure to 6.5 atm.
Strasbourg was renamed Hercules, which now had 70 sq m of heating surface area. Once modified to the Polonceau system, Hercule was rated at 300 tons (45 wagons) in trains measuring up to 240 m long.
