Southwestern Railroad (Kentucky)
Not to be confused with its successor, the Southern Railway, nor with the unrelated Louisville and Southwestern; Louisville, Paducah and Southwestern; and Chesapeake, Ohio and Southwestern railroads, nor with the current Southwestern Railroad in New Mexico, Texas and Oklahoma.
The Southwestern Railroad was a 19th-century railway company in the U.S. state of Kentucky. It operated from 1876 until 1889, when it was incorporated into the Louisville Southern Railroad. It later made up part of the Southern Railway and its former rights-of-way currently form parts of the class-I Norfolk Southern system.
