South Western 0-8-0 Locomotives in Russia


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 9120)

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

The authors say that this was a Mallet cross-compound. The two leading axles were balanced. The firebox had a semi-circular roof and was described as a Haswell-system layout. Both Nevsky and Briansk contributed locomotives of this design.

The class was rated at 15 versts/hour (10 mph) pulling a train of 45,000 poods (787 short tons or 703 long tons) up a 0.8% grade.
