Tamboff & Saratoff 2-4-0 Locomotives in Russia

Class Details by Steve Llanso of Sweat House Media

Class A1 (Locobase 20511)

Data from "Some Past and Present Russian Locos", Locomotive Magazine, Volume XXI [21] (15 November 1915), p. 245 and Volume XXII [22] (15 March 1916), p. 55. Works numbers were 1574-1579 and 1685-1693.

As noted in Locobase 20511, this account provides as much information as the author had about 19th Century Russian locomotives.the LM account provides information supplied by G F Tyas to LM's author about 19th Century Russian locomotives. Compared to the Novotorjock engines, this design featured taller drivers, larger grate and cylinder volume. Once again, an enclosed cab and spark-arresting stack were the principal visible differences from a typical English 2-4-0. On these locomotives, the stack flared vase-like from the small base.
