The Canton-Hankow, of which the Yueh Han was to be a part, had bought some Alco Moguls in 1908 (see Locobase 12981). This pair was Baldwin's contribution to the same basic design; they appear to differ from the Alcos primarily in the use of an inside link motion.

This Mogul trio was an enlargement of the earlier pair of Baldwin Moguls shown in Locobase 13648. An increase in cylinder diameter and in boiler pressure more than offset the 2 additional inches of driver diameter to confer a healthy amount of power on the 2-6-0 design; indeed, the design rose to the top 5% of standard- and broad-gauge Moguls in tractive effort generated and occupied the top 15% of all such Moguls in terms of boiler size and adhesion weight.
