Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 21, p. 159. Works numbers were 15836-15849 in April 1898.
These Vauclain compound Consolidations were identical to the large Vladicaucase order that shipped in 1896 (Locobase 12173) and the later Moscow-Vindbau deliveries (Locobase 3222) that had 14" (456 mm) HP cylinders.
This set soon operated on the Moscow-Kursk Railway.
