The Central Kansas Railway (CKR) (reporting mark CKRY) was a short-line railroad operating 900 miles (1,400 km) of trackage in the U.S. state of Kansas and west to Towner, Colorado, most all of which were former Atchison, Topeka and Santa Fe Railway lines. Owned by Omnitrax, CKR's main business was from the Kansas wheat harvests, as well as other traffic.
The Watco Companies of Pittsburg, Kansas purchased all of the CKR's lines on May 31, 2001 and formed the Kansas and Oklahoma Railroad.
