See [] (15 Feb 2004) (a Ukrainian website organizing steam tours) for the data. Dzherelo says the information comes from Anthony J. Heywood & Jan D.C. Button, Soviet Locomotive Types: The Union Legacy (1995). See also DeGolyer, Volume 57, pp. 390+
The dzherelo site (no longer active) said that the "soft sign" b class covered a variety of wheel arrangements and that this particular series was built over many years by Kolomna, the Nevskii works, and, in one six-locomotive order in 1933, Beyer, Peacock & Company. It's the data from that order -- works numbers 6759-6764 -- that's shown in the specs. If the data are accurate, this has to have been one of the biggest 0-4-0Ts built -- heavy industrial switchers with a surprisingly high degree of superheat and more tractive effort than similar six-coupled tanks.
Data from 1946 Beyer, Peacock catalogue hosted on Martyn Bane's website at [] (accessed 21 May 2006).
Batch #1414 (works#6759-6764) (Production data from The Beyer, Peacock production list -- [], last accessed 29 May 2006).
In the same production lot as the powerful 0-6-0Ts sent to Russia in 1933 were these 4-coupled brutes. Essentially scaled-down from the larger engines, they had the same high superheat, axle loading, generous grate area, and adequate firebox heating surface.
