Paris a Versailles 2-4-0 Locomotives in France

Class Details by Steve Llanso of Sweat House Media

Class Victorieuse (Locobase 4816)

Data 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).

This locomotive may have been the first to have been produced with this wheel arrangement. According to Reder (1974), the smaller leading axle allowed the builder to lay the cylinders horizontally inside the frames. In tests with both passenger and freight trains, the Victorieuse pulled 110 tons at 15 mph up a 0.4% grade.
