Advance 437 (437-A) - Automobile Racks Set Out At Springfield For Kansas City

Does anyone know which late 1970s train went from St Louis to Tulsa/Dallas and worked at Springfield Yard dropping Kansas City automobile racks?

I am guessing 437-A but the Operating Data Sheet I have from 7/25/1979 shows the Kansas City auto racks next to the power.

I think I remember Charlie Dischinger saying that there was a train that went St. Louis to Tulsa / Dallas that had a Kansas City cut of automobiles / TOFC behind the first caboose.

A second caboose followed the Kansas City traffic and was left in Springfield Yard with the Kansas City traffic minimizing the terminal time at Springfield.

I want to duplicate this train on my layout.

Thank in advance for your help.

 

My recollection is that Advance 437 brought the auto racks to Springfield, where the Kansas City cars were set out for train FSE.

Advance 437 was a late night arrival, so I can't attest to a second caboose.
