The 3751 leads a special past a SD40-2 rebuilt into an SD39-2 in Commerce. I think that the sweet light attracted quite a few fellow railfans, as I was sort of entombed by maybe a dozen other shooters (including many Railpictures.net contributors) when I snapped this image. There's something very cool as the locomotive gets closer and closer with just the railroad noise to be heard, and then all of a sudden, there's one SLR mirror clunk, and then another, and then a cacacophy of SLR mirror clunks going off all around you.
