Yes.
I watched a pair of them climbing the hill out of the Mohawk valley towards Selkirk with a train in early 1999. I imagine I have an unscanned slide of that somewhere, but that box is buried pretty deep....
I went and looked. It was 13 March 1999. A much younger me labelled the slide: "Lower Rotterdam Junction, NY; gen ft east, Selkirk Br, 2 CSX AC60W". I'm supposing that's them, though.
They were running elephant style.
