Mountain 4-8-2 Engine

All members of the 4-8-2 family of locomotive wheel arrangements produced good designs. The four-wheel leading truck made the engines track well at speed and the two-wheel trailing truck, as has been pointed out frequently, supported a firebox with good steaming capacity.
With the exception of switching, one or another engine from this family could do most of a  railroad’s jobs.
