Does NS have a tracking tool which shows where locomotives are? Or do we need to rely on the trusty railfan network? With 19 of these on the rails eventually, and NS's far-flung network, it's going to be fun to try to get photos of them. When I lived in Modesto, I had a personal goal to get photos of all 25 of the SP SD70M's. I did it, got the last one a few weeks before we moved to Ohio . I see another challenge here, trying to get all of the NS heritage units
Probably the same way people track the UP units. Via a yahoo group where spotters report locations and ujnnamed sources report what the computers say.
