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. Although these are labeled as BN they seem to be slightly reworked versions of the last Frisco charts. The 27 charts cover almost all that was left of the former Frisco mainline at this date (1982-83). The kind folks at fobnr.org agreed to make them available to everyone online. To check them out go to fobnr.org , click About the BN at the top and then scroll down to 1983 ex Frisco. (Some might find some of the Springfield 1993 charts interesting as well)
Thanks a bunch for sharing. Direct link for convenience https://fobnr.org/bn/bn-track-profiles-1983-ex-frisco-lines/
