Dockside car pusher update

Thanks to Rick Rowlands, who sent me a copy of an original Baldwin/Westinghouse data sheet on the locomotive, I've been able to add quite a bit of information to the listing for Pennsylvania Railroad #3. This is a 3'6" gauge car pusher, a small electric locomotive that was used at the Pennsy's Whiskey Island coal loading facility to push hopper cars around. In between the "real" railroad tracks were narrow-gauge tracks where these car pushers operated; that way they could easily run around cuts of hoppers. They didn't couple but rather used retractable arms to shove the hoppers around.

Anyway, three of these Pennsy car pushers are preserved: one in North East, PA, one in Bellevue, OH, and one at Rick's organization, the Youngstown Steel Heritage Museum. The other two were built by Atlas making #3 the only one of the survivors built by B/W. It was acquired by YSHR in 2016 from the Railroad Museum of Pennsylvania. (The locomotive is pictured above as of 2003.)

So here are the specs, if you're interested:

HELP NEEDED: anyone have any information on the operating history of this locomotive, or the two surviving Atlas-built locomotives? And I'm also in need of dimensional and mechanical information on the two Atlas car pushers.
