UP/DRGW Kansas Joint Line

After the SP-UP merger of 1996, Central KS Ry leased this former Mopac line from UP between Geneseo-Towner. When did this change take place? Two sources tell two different answers: 1997, 1998. Which is correct?

CKR (OmniTrax) leased from Towner to Bridgeport + Lindsborg to Sid + trackage rights into Salina FD-33470 10-3-97 (Decided 10-1-97) / Filing 28425 (from UP) - As far as I know, Uncle Pete is still getting lease payments from K&O/Watco…(took over 6-12-2001 (FD-34030))

Look at the AAR and STB websites, the data is there. AAR rides heard on the operating certificates. (or take your chances with the Federal Register)
