For a state of its size, Colorado railroad jobs are mostly relegated to the Class Is which serve the state, Union Pacific and BNSF Railway, which make up 80% of its total rail miles.
Amtrak also operates across Colorado, notably its very popular California Zephyr. It is a bit disappointing that just a handful of railroads now operate in Colorado considering the state's rich heritage with trains (such as the venerable Denver & Rio Grand Western Railroad).
Aside from the Class Is just a handful of regional, Class IIs and about the same number of Class III, short lines operate in the state. Historically, Colorado was always a major obstacle for railroads due to the rugged and impenetrable Rocky Mountains.
The Denver & Rio Grande/Rio Grande Western was the first to successfully conquer the range through a combination of narrow-gauge and standard-gauge tracks.
The state is also legendary for operating many well-known narrow-gauge railroads during the 19th century's great silver boom. Today, the Rio Grande's main line remains an important component of Union Pacific.
The information provided here is to aid job searches in highlighting those railroads which currently operate within the state. For reasons that are outside of my control I cannot provide direct links to those companies here or their career pages. However, by doing a quick web search using the Google Search Box below you can find both on the web.
One thing which I have constantly stressed if you are considering a career or position in the industry is just how hard the job actually is, especially if you are unfamiliar with railroads and how they operate.
In particular this holds true for the large, Class I railroads where, because they operate such a large system an employee can be placed wherever they are needed and work incredibly long hours.
For instance, if you are interested in California railroad jobs but hire on with either Union Pacific or BNSF Railway you might be placed along their eastern regions in states such as Illinois, Texas, or Louisiana.
Lastly, once again I must stress that contacting me concerning potential job openings or inquiring about a particular position is of little use because there is simply not much I can do to help.
For more information you will need to contact the individual railroad to see about openings (larger short line conglomerates such as Genesee & Wyoming, Watco, and Patriot Rail requests that all potential job seekers visit the employment page at their respective websites).
While addresses are often included here for many companies, I cannot fully guarantee that the information is completely up-to-date or accurate (please research, yourself, to be sure).
Please note, while many smaller railroads also have websites or web pages, they are not included here. However, by doing a quick search you can find their site on the web.
