I recently discovered a set of BN ex-Frisco track charts at a train show and purchased the set to obtain the chart I wanted. The 27 charts cover almost all that was left of the former Frisco mainline at the dates 1982-1983. They seem to be slightly reworked versions of the last Frisco charts, although they are labeled as BN. They are available to everyone online from the kind folks at https://fobnr.org/. To check them out go to https://fobnr.org, at the top click on About the BN, click on Track Profiles, then 1983 Track Profiles (ex Frisco Lines). https://fobnr.org/bn/bn-track-profiles-1983-ex-frisco-lines/ Some might find some of the other charts interesting as well. Go to 1993 Track Profiles, Southern Corridor, Ft. Worth Division, Kansas City Division, Memphis Division, River Division, Springfield Division and Tulsa Division.
