New Hampshire is one of the few states where landing a job with a railroad may be a bit difficult given that no Class Is operate there and only a handful of smaller railroads do. If you are interested in New Hampshire railroad jobs the largest company located there is Class II, regional Pan Am Railways. Along with Pan Am there are currently eight Class III, shortlines found in the state. Additionally, Amtrak operates its Downeaster service through extreme southern New Hampshire. Overall, the state is rather devoid of trains (and freight traffic in general), with less than 500 miles currently in operation.
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.
If you are seriously interested in becoming a railroader it would do you well to research it all a bit beforehand (if you are not familiar with the industry). Railroading is one of those careers you truly have to enjoy, at least a little, to stick with it for twenty, thirty, or forty years. It requires one to be away from home for long periods of time with completely unpredictable hours. If you are interested in a more predictable work schedule and being with family often then life as a railroader probably isn't for you. While Class Is, which offer the best pay in the industry, do not operate in New Hampshire CSX Transportation is located nearby and you may want to check into the railroad's available openings. Remember, though, that by hiring on with a Class I like CSX you will be located wherever they need you (which could be as far south as Florida or as far west as Chicago).
