When you say it’s “half of a GG1”, do you mean like the front half looks like a GG1 and the rear half looks like something else, or do you mean it looks like a GG1 only 1/2 as big? PRR did have some other, smaller electrics that might be what you’re seeing if the latter.
BTW even if you can’t post the picture here, you can post a link to the page on the website where the image is so we can look at it.
It was a GG1 that was damagd and they cut the unit in half and blanked off the area where they cut it. I don’t remember the number. They used it as a maintenance unit for clearing yards as a snow blower or something like that.
Note the plenum ending close to the tracks - this was used to keep the track clear around the Wilmington shop facility, and I believe it ‘doubled’ as a Wilmington shop switcher.
Comment in Trains Magazine in the '60s when this was first reported: “wouldn’t two of these make a great engine?”
Interesting. Thanks for the info. I wondered what the plenum was for. Follow up question, what generated the heat to melt snow? If it was towed around then presumably no overhead wires.
The half G was the 4846 in it’s original life. The conversion was done in the PC era. It was used as a snow blower to clear out turnouts at Edgemoor Yard in Wilmington Del. – Ken
It didn’t need any heat as it was not meant to melt snow - just blow it off the track. It had a pantograph to supply power to run the blower and could be used only under catenary. Most (but not all) of the track in the shop yard was wired.
