The Chicagoan and Kansas Cityan were a pair of American named passenger trains operated by the Atchison, Topeka and Santa Fe Railway.

[3] In early April, the Santa Fe announced that the route would be extended from Kansas City to Wichita.

[10] On January 6, 1948, the Chicagoan and Kansas Cityan began carrying Chicago–Dallas sleeping cars and coaches, which ran on the Fast Fifteen and Chicago Express south of Oklahoma City.

The Santa Fe began operating a Dodge City–Great Bend–Newton round trip, trains 311/312, which connected with the Chicagoan and Kansas Cityan at Newton in both directions.

[24] The Chicagoan began making local stops east of Kansas City only for passengers coming from train 312.

The Chicagoan, Kansas Cityan, Tulsan and Oil Flyer (another Tulsa–Kansas City train with Chicago connections) were among those proposed to be discontinued.

[32] The ICC granted permission in March to discontinue the Oil Flyer, but ordered the Tulsan kept for a year.

[34] The final runs of the trains were on April 17–18, 1968, leaving only the Texas Chief on the Santa Fe's Chicago–Texas route.
