Data from "Some Past and Present Russian Locos", Locomotive Magazine, Volume XXI [21] (15 November 1915), p. 246 and Volume XXII [22] (15 March 1916), p. 55. Works numbers were 1604-1611.
As noted in Locobase 20511, the LM account provides information supplied by G F Tyas to LM's author about 19th Century Russian locomotives. This Leeds product was built to French specs after an earlier deal with Schneider-Creusot was annulled by the outbreak of the Franco-Prussian War in 1870.
Slightly larger than the Moscow-Riazan six-coupled goods locomotives shown in Locobase 20512, these engines had smaller drivers and a small increase in boiler pressure, so they generated a bit more tractive effort. Six tons more loaded weight meant a higher factor of adhesion. Their fireboxes were designed to burn wood, lignite, or soft coal. A vase-on-stem stack shape betrayed the spark-arresting system required by such fuels on mostly forested roads. Compared to the Moscow-Riazan, this engine's dome sat directly over the lead driving axle (and thus resembling French designs) and had a small sand dome immediately behind the steam dome.
