Stupid question: could these fan motors operate reliably if inclined slightly? Unless I misunderstand how the fans are located relative to the access doors, I would think there's enough room with ducts above and below the fans to angle the forward one slightly even with 'obtrusion' into the intake space at the front.
Are there good available drawings that show the arrangement, or pictures with the fan inspection doors open?
DanRaitz Not necessarily, by doing a quick and dirty (eye-ball) check of Athearn's BB SD40T-2 and GP50, the radiator sections are the same length. So, you could feasibly take the radiator section of the SD40T-2 and graft it onto the GP50 with no increase in length.

As I said, I believe it was the same length, however, it's not the radiators that would drive the length, it's fitting two cooling fans below the radiators between the air compressor and the rear sandbox while not obstructing the forward fan inlet too severely. The cooling system consists of two parallel sets of 3 double length radiator cores (54" long, 30" wide, 6 tube rows deep) with the fans biased to the rear two double length cores which may make the forward core less effective - the fans need to be as far from the radiators as possible to make full use of the core length. No doubt the cooling system engineer would have made a physical mock-up and tested it to insure design performance if an order materialized, but that never happened.

I pretty sure it was to be the same length as a standard GP50 but I don't have copy of the general arrangement drawing to know positively, at most it would have 37' truck spacing - we always avoided anything closer to 39' to avoid lining up with rail joint spacing. I do recall it was to have two 48" cooling fans similar to an SD40T-2 which the higher fan speed tied to 950 rpm engine speed made work. It had a standard 3 cyl water cooled compressor in the normal location to the rear of the equipment rack with a curved shroud over it to keep it inside the engine compartment.
This is PLI 92061. I think Dave Goding will have specific information on this.
