The Twin Cities and Western Railroad (reporting mark TCWR) is a railroad operating in the U.S. state of Minnesota which started operations on July 27, 1991. Trackage includes the former Soo Line Railroad "Ortonville Line", originally built as the first part of the Pacific extension of the Milwaukee Road. This main line extends from Hopkins, Minnesota (a Western suburb of the Twin Cities) to Appleton, Minnesota. The line was originally built between Hopkins and Cologne, Minnesota in 1876 by Hastings and Dakota Railroad. In 1913, the Milwaukee Road rerouted it, reducing the curves. The line was eventually extended to the Pacific.
