Data from Apercu des Chemins de Fer Russes Depuis l'Origine Jusqu'en 1892, Editor in Chief Andre de Gortschakov (Brussells: Paul Weissenbruch, 1897), p 77. See also "Fairlie Engines", Engineering, Volume , (14 December 1877), pp. 462-463.
These Sharpies were most like a quartet of Avondale Fairlies that were delivered to the Trans-Caucasus in the same period (see Locobase 3261). Compared to the Avondales, this sextet has less firebox heating surface.
A stout opponent of the Fairlie design was J F L Jetter, who wrote the Engineering in 1877 to give what he asserted was an objective account of the design's failings. Drawing his evidence from a letter written by representatives of Beyer, Peacock, he hastened to amend one comment. The BP letter asserted that the Fairlies might overcome their difficulties were they better made. Jetter said that other Sharp, Stewart engines operating on the same line were outperforming the Fairlies.
The adverse comparisons with Beyer, Peacock's six-coupleds included two more crew required, twice as much wood and almost twice as much oil per 100 miles, and only 37% of the average distance covered before being pulled out of service for repairs.
