Data from "Tank Locomotives for the Southern Manchuria Railway," The Railway Age, Volume 45, No 5 (7 February 1908), pp. 187-188.
The RA report spotted the two principal differences between these five dozen tanks for Manchuria and the two dozen sold to Isthmian Canal Commission in 1906 (Locobase 11459): a reduction in gauge and a slight increase in engine wheelbase. Otherwise, the Chinese engines were duplicates of those then at work in Panama.
