If you are interested in New Mexico railroad jobs you have few options outside of the large Class I companies (BNSF Railway and Union Pacific) as the state is primarily home to their through main lines which connect Chicago with Los Angeles. Today, BNSF and UP make up nearly 81% of the states total trackage with just a few short lines (Santa Fe Southern Railway, Southwestern Railroad, Texas-New Mexico Railroad, and Arizona Eastern Railway) making up the rest. Additionally, Amtrak operates through New Mexico and the recently started New Mexico Rail Runner Express commuter train serves the Albuquerque region.
If you are seriously interested in pursuing a railroad career, especially in either the transportation or maintenance fields (which include such positions as conductor, engineer, or general track maintainer), the work can be brutally difficult. Today, the physical demands are not quite the same as they were before heavy mechanization decreased the need for so much human labor (although it hasn't completely disappeared). However, perhaps the hardest aspect of the job is the sheer number of hours you must be on call, which usually means long, 12-hour days. While smaller railroads usually offer a more predictable work schedule they cannot match the level of pay, benefits, and retirement of Class Is. Ultimately, it comes down to whether you think a career as a railroader is right for you. Lastly, if you are a college student you may want to see what internship programs BNSF, Union Pacific, or really any of the Class I railroads have to offer. Most offer some type of summertime management/business program for college students to help them get an early start in the field. Finally, I cannot guarantee that the contact information listed here is entirely, 100% accurate. However, as far as I am aware it is up-to-date.
