Data from DeGolyer, Volume 21, p. 199; and Burnham, Williams & Co., Record of Recent Construction, No 8, pp. 12-13 in Numbers 1-10 Inclusive. See also "Compound Locomotive for the Chinese Eastern Railway," The Locomotive & Railway Carriage & Wagon Review, Volume IV [4] (March 1899), p. 126. Works numbers were 15966-15977 in June 1898 and 16053-16067 in 1899.
A full description of the Chinese Eastern was recorded in Locobase 10115. In addition to the sizable order of Consolidations, the CE also purchased this double-dozen-plus-3 of balanced compounds radial tank engines. (These were identical to the single engine delivered in the same month to the Nicoprol Maricopol Mining Railway (Locobase 12278) except for the compounding layout.)
Each set of one HP and one LP cylinder used a single 8" (203 mm) piston valve comprising front and back halves. As in the specifications for the 0-6-2Ts described in Locobase 3230, the front and back ends of the piston valves could be joined in one of two ways. The builder could either bolt the two halves together (presumably around the circumference of the castings) or through a prolongation of the valve stem & fixing it at each end of the piston valve.
A note in the specification required that the pipes leading live steam to the HP cylinders and exhaust steam from the LP cylinders to the stack avoid blocking the ends of the smoke tubes.
Their very small drivers made the Radley & Hunter cabbage stack look even bigger.
