South Western 4-4-0 Locomotives in Russia


Class Details by Steve Llanso of Sweat House Media

Class 101 (Locobase 8886)

Data from "Machine des Chemins de Fer du Sud-Ouest russe," Revue gTnTrale des chemins de fer, Vol 16 (January 1893), pp.64-65

This was a later batch of South-Western tandem compounds that had bigger cylinders in both HP and LP positions. The earlier batch is described in Locobase 9113.

The Revue article notes that this locomotive was designed by Alfred de Glehn and builtin the company's shops to pull 15 passenger cars of 16 metric tons each (240 tons) at speeds up to 80 km/h (50 mph). This represented a considerable improvement over th 130 tons and 50 km/h (31 mph) that was then the standard.


Class unknown (Locobase 9113)

Data from Apercu des Chemins de Fer Russes Depuis l'Origine Jusqu'en 1892, Editor in Chief Andre de Gortschakov (Brussells: Paul Weissenbruch, 1897).

These engines were designed to pull 10 carriages at 60 versts/hour. They were tandem compounds with Belpaire fireboxes. Later examples of this design had bigger cylinders, but were otherwise similar; see Locobase 8886.
