Conrail eventually owned the former-Monon C628s before they were scrapped. The CR C628s were numbered 6729 - 6737. Unfortunately, CR later had a set of SD-50s that were numbered the same. Both locomotives were six-axle.
When looking at a photo of a CR locomotive in this numbering scheme, how do tell whether it is a C628 or an SD-50?
