Title 15 › Chapter CHAPTER 6— - WEIGHTS AND MEASURES AND STANDARD TIME › Subchapter SUBCHAPTER IX— - STANDARD TIME › § 265
Moves the Panhandle and Plains parts of Texas and Oklahoma into the U.S. Central Time Zone. The Secretary of Transportation must set the western edge of that time zone for Texas and Oklahoma along a line that begins where it meets the Kansas–Oklahoma border, goes west to Oklahoma’s northwest corner, then south along the western borders of Oklahoma and Texas to New Mexico’s southeast corner, then west along the Texas–New Mexico line to the Rio Grande, and then follows the Rio Grande as the U.S.–Mexico border. Allows certain railroads to pick specific towns as their switch point between Central and Mountain time: Chicago, Rock Island and Gulf and Chicago, Rock Island and Pacific may use Tucumcari, New Mexico; Colorado Southern and Fort Worth and Denver City may use Sixela, New Mexico; Atchison, Topeka and Santa Fe and other Santa Fe branches may use Clovis, New Mexico; and railways going into or through El Paso may use El Paso. Otherwise, this does not change other time-zone actions by the Secretary of Transportation.
