The Missouri–Kansas–Texas Railroad (reporting mark MKT) is a former Class I railroad company in the United States, with its last headquarters in Dallas. It was established in 1865 under the name Union Pacific Railway, Southern Branch and served an extensive rail network in Texas, Oklahoma, Kansas, and Missouri. In 1988 it merged with the Missouri Pacific Railroad and is now part of Union Pacific Railroad.
In its earliest days the MKT was commonly referred to as “the K-T”, which was its stock exchange symbol; this common designation soon evolved into “the Katy“.
The Katy was the first railroad to enter Texas from the north. Eventually the Katy’s core system would grow to link Parsons, Fort Scott, Junction City, Olathe, and Kansas City, Kansas; Kansas City, Joplin, Jefferson City, and St. Louis,Missouri; Tulsa and Oklahoma City, Oklahoma; Dallas, Fort Worth, Waco, Temple, Austin, San Antonio, Houston, and Galveston, Texas. An additional mainline between Fort Worth and Salina, Kansas, was added in the 1980s after the collapse of the Chicago, Rock Island and Pacific Railroad; this line was operated as the Oklahoma, Kansas and Texas Railroad (OKKT).
(Fun fact: Mike’s dog is named after this RR, Ms. Katy)
