Actually, I think that cropping even more and getting rid of the guy in the green shirt and the walkie talkie might improve this photo. I love trains and photos of them, so this one is a keeper for me!
"Where there is perhaps a province in which the photograph can tell us nothing more than what we see with our own eyes, there is another in which it proves to us how little our eyes permit us to see." ~Dorothea Lange
....I wouldn't worry about it being cropped, you do that to create an image that is pleasing to your eye and I think you did it right ...and I like the inclusion of the man - I think he adds interest to the photograph and obviously has a role to play!
