Before and After

I'm thoroughly enjoying RailPictures.net, even though they rejected my only submission. :-( Ah, well, I'm a total amateur, but I'll learn how to take better shots by seeing what others are doing. One very impressive twosome of shots were on the site. Check them out:

Amtrak engine #69: Before Picture.
Amtrak engine #69: After Picture.

The difference was the gravel truck that drove around a crossing gate.
