Bologi-Briensk 0-8-0 Locomotives in Russia

Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 20517)

Data from "Some Past and Present Russian Locos", Locomotive Magazine, Volume XXII [22] (15 March 1916), p. 56-57, and 15 May 1916, p. 96 for a correction.

This design was essentially a French locomotive brought to Russia. The author notes that Cail had built many similar locomotives for France's CF de Nord, and clearly Fives-Lille followed the pattern. The look of the wood-burning locomotive, if one can ignore the full cab with glazing and a vase-like spark-arresting stack, is quite Gallic and thus untidy to some ferro-equine aesthetes.

The boiler's sand "dome" is a box placed above the third axle. Its dome sits well forward between the first two axles and the regulator box's external steam pipes snake down the boiler on either side to supply the valves located inside the frame. The reach rod extends forward to move the external link to the Stephenson valve motion, which was usually tucked inside in British engines.

But the author explains that the "structural simplicity of these locomotives--all the mechanism outside the wheels--rendered them particularly suitable for service on lines somewhat poorly provided with pits and workshop facilities."
