The Texas Mexican Railway (reporting mark TM) was a short line railroad in the U.S. state of Texas operating between Corpus Christi and the Texas Mexican Railway International Bridge in Laredo, Texas. It is often referred to as the Tex Mex, or Tex Mex Railway.[4]
The railroad traces its roots back to the Corpus Christi, San Diego and Rio Grande Gauge Railroad, a narrow-gauge railroad established in 1875. In 1883, the line was extended over the Rio Grande and the Mexico–United States border. The railroad was purchased by the Mexican government in 1900, which controlled the railroad until 1982 when it was sold to Transportación Maritima Mexicana (TMM). In 1996, Kansas City Southern (KCS) became a 49% owner of the railroad, as part of a larger business deal. KCS bought out TMM in 2005 and made Tex-Mex a wholly owned and consolidated subsidiary of its Kansas City Southern Railway.
Canadian Pacific Railway purchased KCS in December 2021 for US$31 billion. On April 14, 2023, the railroads merged to form Canadian Pacific Kansas City (CPKC). Lines originally operated by Tex-Mex are now a vital link in CPKC's rail network, the first and only to directly serve Canada, Mexico and the United States. One of the major arguments for the merger was that it would increase competition in the Chicago–Mexico corridor that had been dominated by Union Pacific and BNSF Railway.
