Data from Mr. Thomas Urquhart, "On the Compounding of Locomotives Burning Petroleum Refuse in Russia", Institute of Mechanical Engineers (London, IME, 1890), pp. 107, 110.
Urquhart's discussion concerned the conversion of some of these eight-coupleds into tandem compounds. This entry shows the original engines. At the time of its compounding, the class was rated to pull 720 tons up a 1 in 125 (0.8%) grade.
