For being the smallest Class 1 in the US; this railroad seems to be doing OK. What smaller RR's were put into KCS to make it the RR it is today? Both here in the U.S. and internationaly.
The core KCS system remained essentially the same until the 1990s, when the purchase of the MidSouth Rail Corporation extended KCS's reach eastward from Shreveport and into Mississippi and Alabama. This acquisition, combined with existing KCS routes, created a key east-west mainline marketed as the Meridian Speedway (named for the town of Meridian, Mississippi). An additional acquisition, the Gateway Western Railway, extended KCS's reach from Kansas City to St. Louis, Missouri, and to Springfield, Illinois. The 1990s also saw KCS extend its reach into Mexico, with the acquisition of partial interests in the Texas Mexican Railway and Grupo Transportación Ferroviaria Mexicana. In 2005, KCS was successful in acquiring a controlling interest in both roads.See also: http://en.wikipedia.org/wiki/Kansas_Cit ... rn_Railway
