CP 9110, a GMD SD90MAC sits in the Dryden yard with a SD-40-2 (CP 5976) trailing. These units where the power of a (rail) work train.

Using the live view function of the Canon 40D, I had to hold the camera over my head to shoot between two strands of barbed wire on top of a fence to get this shot. I couldn't get too much of the second unit as there was a tree in the way - as evident of a dark shadow above the second unit.
