Amtrak operates the Southwest Chief between Chicago and Los Angeles, making stops in Las Vegas and Raton (before moving on to Lamy—near Santa Fe—and Albuquerque). As part of a longer trip along this fabled route, taking Amtrak to Las Vegas or Raton can be interesting—you can get around both towns without a car. But if your aim is to explore anything outside these two towns, train travel isn't practical. 800/872–7245. www.amtrak.com.
