Data from "Some Past and Present Russian Locos", Locomotive Magazine, Volume XXII [22] (15 March 1916), p. 55. (Thanks to
Piotr Staszewski for his 1 September 2025 email correcting the works numbers for this pair. Piotr later identified the railway's name, which appears below.) Works numbers were 1707-1708 in 1871. (1709-1710 came out of Kitson's shops as tenders for the pair.)
In response to a Locobase question about the railway name, Piotr Staszewski replied "I can not find an official name of this railway.
In literature it is simply "Livenskaja Zheleznaja Doroga" (Livny railway or more literally "iron way/road"[in Russian]")
It was "Imperial' in the sense that is was state {treasure/fiscal) owned but I do not remember any "Imperial ..." railway name in literature."
As noted in Locobase 20511, the LM account provides information supplied by G F Tyas to LM's author about 19th Century Russian locomotives. LM's report comments that these narrow-gauge Mogul locomotives were "well adapated for their work, being light in relation to their power, and very economical on account of their good proportions and general simplicity."
The 3/4-scale design sported a generous cab and vase-like spark-arresting stack that, combined with the small-diameter running gear, gave a toy-like appearance.
