It's always nice to see someone acquire an interest in the awsome world of railroads. I am 27 and have been infatuated with trains for 25 years. As my screen name implies, I work for a shortline RR and I enjoy my job. Of course there are easy and hard days, but all in all I like it.
Be VERY careful around railroad tracks. My own rule is that I stay off the right of way. If you visit a yard, it is best to go to the office and ask permission to watch/photograph trains. By and large, railroaders are a cordial group of people and if you extend common courtesy, it will be reciprocated. On a few occasions I spent longer visiting with the men inside the office than actually watching trains.
