From Robert Krol: I'd say your POTW is the 1807. Check out your pics. Oil leaks on fuel tank similar. Here's the other side. (1, 2, 3)
From Curt Fortenberry: I'm speculating that GP7 frame is 1807, it was wrecked during the winter of 83/84, and retired March 84. Story has it there was a hard couple in Fairbanks during one of the super cold days and the front was damaged (fell off is what I was told). Seeing that I don't see a front pilot on that image, I'm guessing that's pretty close. The shot is looking at the rear of the unit (look where the air tanks are).
Patrick Durand: The four stacks Identify this as one of the ARR GP7 units numbered 1801-1810. 1801, 3, 8, 9 were sold outside so this leave 2,4,5,6,10 for eliminations in the the hunt for the road number.
Jerry Peters:
During the period that the 1800's were being rebuilt, it was decided that the last three units sent to Paducah (1807, 1808, and 1809), would be equipped to act as electrical power generators for operating the Rotary Snow Plow no. 3. At that time ALCO 1050 class B-units were being used for this service but were somewhat under powered for this duty.
The modification added an additional 27 pin jumper cable receptacle, painted red and stenciled as to what it was for, just below the normal one on the front of the engine only. A small receptacle was also added just below the red receptacle. This was the 74 VDC power supply to the Rotary as it didn't have batteries or a generator for that control voltage. Just inside the air brake train line valves on each side, two high voltage, 1000 amp (I think) single pole receptacles were installed to provide power to the two traction motors used to operate the snow thrower wheel on the front of the Rotary.
My shop (Electric Shop) started to install the necessary equipment in the Rotary 3 to make it work with the above mentioned engines, but was put to the side without much being accomplished. We never were able to complete this job as it was decided by the new management that we did not need to use the Rotary's anymore. The Milwaukee Rotary arrived a while after this but that is another interesting story.
I looked thru your 1800 picture section and found the "the sold GP-7's" line. It shows that the 1808 and the 1809 were sold off at that time (this was after I had retired from the RR.) That leaves only the 1807. I must say that it looks like the unit was involved in an accident as the electric cabinet is tipped somewhat toward the front, and the concrete ballast located forward of the cab, in the nose has been moved considerably from its intended location.
