Very interesting low-angle, the train exactly on the bridge and filling the bridge - maybe wish it could be a little bigger?! And just one engine pulling that whole thing!
Putting your pictures in my favorites is the highest honor I can give you. If I do not get to your pictures as soon as you post them, I apologize. I try. Also if I do not respond for awhile it doesn't mean I'm ignoring you, it just means I'm really tied up with life.
Now that's a great shot! It has a feeling of lonely vastness. Ordinarily I woould say that it should follow the rule of thirds, but you centered the train and it works very well leaving just enough space ahead of it to give a feeling of the train going somewhere. The escarpment behind the train really dwarfs it, which is pretty cool given how big those things are. If the foreground post were not present (and if I were in the voting booth!)I'd give this shot a 10
