Frisco 4-8-2s on River Division.

[WILLIAM O CRAIG]

These were passenger engines, and I imagine none of the passenger trains on the River Division were heavy enough to require them, with the 1000-class Pacifics up to the job Also, the 1500s were needed for runs in the hilly Ozarks, not so much for the more level River Division.

Why none of the 30 Frisco 1500 Class 4-8-2 Mountains ran on the Frisco River Division between Memphis TN and St Louis MO
