It appears the Frisco used a partnership with C&EI to access the Chicago market.

"This Frisco System map was created prior to 1941 as it does not show the extension to Pensacola, Florida. (St. Louis–San Francisco Railway Company Records (R0362), State Historical Society of Missouri)"

Its connections in Birmingham are SCL, so this would have to be after the merger of ACL and SAL, which was 1967.

Since this is a BNSF map, I presume it was at the time of the merger in 1980.
