River Division Steam Locomotive Types From Saint Louis, MO To Memphis, TN - 1940s-1950s - Inquiry

What steam locomotive wheel arrangement ran on the Frisco River Division from Saint Louis, MO to Memphis, TN in the steam era?

I think 4-8-2s is the answer.

 

During what time frame should be part of the question.

 

The 1940s until Frisco's end of steam in 1952.

By the way, sorry about the misspelling of Division.

 

Between August 1940 and August 1941, the Frisco's West Shop forces built 5 4-6-4 Hudson type locomotives, SLSF 1060, 1061, 1063, 1067, and 1068, for service on the Oklahoman and the Memphian.

The Sunnyland was in the hands of one of the 1040-class 4-6-2s.

During the war years the light USRA Mikados handled through freights, and the local work was in the hands of the 1200 and 1306-class 2-8-0s and the newer 4-6-0s.

The Frisco-built 1350-class 2-8-2 Mikado types began working during the 1943-1946 period.

It was not until the transition-era that the 1500 4-8-2 Mountain class began to appear on The Sunnyland and Memphian, and the 4100 4-8-2s began to handle through freights.

 

In fact, the 2-8-2 Heavy Mikados with 12 wheel tenders pulled the troop trains on the River Division line to Memphis after 12/7/1941.
