Data from DeGolyer, Vol 60, pp. 260. Julean Arnold, Commercial Handbook of China, Volume I, Miscellaneous Series-No 84 (Washington, DC: Government Printing Office, 1919). Works numbers were 42556-42558 in October 1915.
Altogether, Baldwin would supply nineteen Consolidations with 19" x 26" cylinders. The first three had saturated boilers and are shown in this entry. Almost five years later, Baldwin would supply the superheated variant shown in Locobase 14643.
Data from DeGolyer, Volume 60, pp. 264. Works numbers were 52821, 52844-52845,52862-52863, 52909-52910, 52941 in January 1920; 53548, 53580-53581 in August; 53635-53637, 53641-53642 in September.
These small, superheated Consolidations were derived from the saturated-boiler design shown in Locobase 14647. 98 small tubes were sacrificed for 19 flues carrying a moderate amount of superheater.
Because they operated on 60 lb/yard (30 kg/metre) rails, the axle load given in the specs was intended to be a maximum. In fact, "every effort" was to be made to keep the loading below 30,000 lb.
The engines came painted according to a freight standard of all black, but the face of the front bumper and the rear face of the tender's back bumper were to be "signal red."
Data from DeGolyer, Vol 60, pp. 276. Works numbers were 41466-41467 in June 1914.
