The light here is gorgeous - it seems to be that lovely soft light of either morning or evening. Great find with the tree growing there - makes you wonder if it was intentionally planted or just sprung up on its own.
Your composition is good here. I like how the tree provides a "stable" starting point, and the train leads the eye out of the frame. The colors are a bit strange to me. It almost looks like you brightened it too much in pp, or applied too much of a curves adjustment to it and it caused you to lose some details.
this looks great on my monitor at work... and just like that Whitting guy, though personally I think your subject matter is more interesting. Better composition, too.
