This thread is now almost eight months old, but if you are still looking for railroad work in Maine, your best bet would be to check out the web sites of the various railroads and see if they have any job postings. If they do, send in an application or resume.
Railroad work "is what it is" as they say, but for the most part, MMA and SLR are pretty good companies to work for, all things considered. There is also the Maine Eastern, but they're quite small and probably don't have much turnover. Nevertheless, it can't hurt to look into it. They run from Brunswick to Rockland, which is certainly a very nice and pretty part of the state, and the winters on the coast aren't quite as rugged as Up Nawth in MMA territory.
There is also Amtrak from Portland to Boston, if you'd prefer to live in the more "urban" part of the state. (Not that there are really any truly urban areas in Maine!)
