At the time of its incorporation, consolidations were also made with the Labette & Sedalia Railway Co. and the Neosho Valley & Holden Railway Co.; MK&T also acquired the Tebo & Neosho Railroad Co., the St. Louis & Santa Fe Railroad Co., and the Hannibal & Central Missouri Railroad Co. Combined with the UP Southern Branch, these small, newly built railroads formed the foundation on which the Katy built. In the late 1890s, a subsidiary once called the Missouri-Kansas-Eastern railroad was established to run from existing MKT rails approaching Kansas City into St Louis via the Missouri River basin.
