Est 2-2-2 Locomotives in France


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 605)

Data from a site that reproduces cigarette card pictures and adds dimension and area data -- [], last accessed 14 June 2006.

Representative of the Stephenson "long-boilers" as built in France. Originally supplied to the Montereau, which later was taken over by L'Est. The photograph shows a classic profile of a design produced less than two decades after the Rocket. The two carrying axles flanked the driving axle with large and open-spoked wheels. The safety valve stand stood on the boiler just ahead of the drivers and behind the enormous "dust-bin" dome, which was just behind the tall stack that had a flared top. All polishable parts gleam brightly in the sun and the locomotive's two-man crew is ready.

They were rebuilt as 2-4-0s; see Locobase 7578.


Class 136 (Locobase 11296)

Data from August Perdonnet et Camille Polonceau, Nouveau Portefeuille de L'Ingenieur des Chemins de Fer, Tome Second (Paris: Librairie Scientifique, Industrielle et Agricole, 1866), pp. 524.

See also Locobase 621, which has somewhat different data from an earlier Perdonnet work.


Class 158 (Locobase 11297)

Data from August Perdonnet et Camille Polonceau, Nouveau Portefeuille de L'Ingenieur des Chemins de Fer, Tome Second (Paris: Librairie Scientifique, Industrielle et Agricole, 1866), pp. 524.
