Missouri-Kansas-Texas (MKT)
The Missouri–Kansas–Texas (MKT) was a roughly 3,765 mile Class I system under the Union Pacific Railroad. It was established in 1865 and it served an extensive rail AND road network in Texas, Oklahoma, Kansas, and Missouri. In its earliest days the MKT was commonly known as “the K-T” which was also its stock exchange symbol and soon evolved into “the Katy“. The MKT also endeared itself unto many railfans under the moniker of “Miss Katy.”
In the 1980s after the the Chicago, Rock Island and Pacific (Rock Island) went defunct an additional mainline between Fort Worth, Texas and Salina, Kansas was added and was operated as the Oklahoma, Kansas and Texas Railroad (OKKT). In 1988, the MKT merged with the Missouri Pacific (MP) “MoPac“ Railroad and eventually became a part of Union Pacific.
