Railroad Companies in Louisiana in the late 70s?

[stephanh]

Hello,

I am looking for major railroad companies in Louisiana in the late 70s.

I already found the following:

Rock Island
Santa Fe
Cotton Belt
Southern Pacific
Kansas City Southern
Missouri Pacific
Southern
Illinos Central Gulf
Louisville & Nashville

Any more Class 1s?

I guess The Frisco did not go so far, and the Union Pacific came later after the mergers...

Hope to hear from you.

Kind regards.
