This one needs color, but a crop would be sacrilege.
Hey take it easy, master Russ! I only meant to emphasize the underlying pattern of the movement of the trains. Not literally crop the image. But having said that, a crop would work. Russ, the old school, the 'New York school of Photography', had an assignment that consisted of cropping a physical image in six ways. Never attended, but my friend showed me some of the school materials many years ago.
The color version is definitely more dynamic. The color on the trains, combined with trains as lines, helps the eye move through the image. Oh, what to do...
