I like the shot and the grayscale works well. ALso the angle of the road to the tracks is very interesting and the detail is easy on the eye. The only part that I would have changed is a little less sky (or a different cloud) as the bright cloud in the middle takes away from the overall effect in the picture.
I like it although I think I'd prefer it more as two seperate pictures with either the road or rails leading into the photo instead of having both leading the eye out of the photo. Hope that makes sense. What ISO were you using?
I don't feel that the huge expanse of sky adds to this photo, but I do like the very diverse angles. I'd like to see this recropped, and I'd be tempted to add a bit more contrast.
I dig this image. Good eye there, for noticing this angle. I love the B&W. My only suggestion would be what's already been mentioned: crop out a bit of that sky (although I understand why you like those clouds, they're gorgeous but pull the eye away from your crossing) and bump up that contrast a little.
