Why not pursue your original dream? Just google 'locomotive engineer', there's a wealth of good info on the first results page. Don't force yourself into a career path you won't enjoy, do what makes you happy. Honestly I thought about doing the same at one point, but then I discovered video games, and that's what I'm studying now is game design. It doesn't pay that great but heck, it's what I enjoy doing.
[Although I still think trains are awesome. Someday when I get a house and have money I'm definitely going to get into model railroading.]
