Looks to me to be a photoshopped pic, which makes it real hard to guess.....I base that on the wandering focus in the picture......which probably means model. For the distances involved, I think if it was real, everything would be in focus, or at least a lot better focus. Notice that the grey hopper in the third row back is quite blurry, the DT&I hopper is slightly out of focus, but the yellow boxcar in the 4th row has areas that are in good focus (ORG, ORTHWE, RAILR). And the couple thing Larry mentioned....you can see the couplers between the BN hopper and the car to the right, and the airlines look like they cross (like a model) not connect together.
