For BW this image is quite gray overall. W is reserved for skies and little detail at left rocks. The best portion is bottom right quadrant where the tones go well together. The feeling is that train needs to climb a bit, so with faster speed it would rock over poor photographer. Luckily there's no sense of speed here, so the feeling transforms into idea of heavy weight cargo being pulled. Too bad the mechanical topic is slightly dismissed by trains facade highlights caused by electronics.
Nice shot and I will even ignore the electronics that are probably involved in moving that thing. One gripe, the CSX colors might have looked pretty neat against the predominately grey/brown of the winter landscape.
Needs elelctronics to operate. Therefore, does not meet challenge. I like trains and train pics...this is a different view thtn teh traditional - based on sizing of the elements in the picture, ieach is given equal weight (ballanst, loco, trees, hillside and even the rail ) This 'balance' is not traditional - usually the element you want me to focus on is largest or otherwise pointed to by the composition. In this case the composition fails.
