This is a unit which was requested of EMD by the D&RGW, and though never built, I have the idea it was at least designed and put to paper.
Have any of you ever stumbled across these drawings by chance? I have basic GP50 drawings (Mainline Modeler), as well as drawings (in the data book, and also by Hundman publishing), of the GP15, which sports the same rooftop radiators as do the SD40T-2, SD45T-2 and MP15 AC, and what it probably a single large fan pulling cooling air from walkway height upward and through the top mounted radiators. A GP50T would have at least two I'm sure (as does the SD40T-2) but probably not three (as does the SD45T-2). The last--three fans--just seems like it would take up too much hood length for the short 4-axle frame. And if it did, it would probably be overthrust at both ends, perhaps even over the anti-climbers.
It's a puzzler. Imagineering, really, what EMD might have done, or just tried to do but never quite pulled together.
Any GP50 internal diagrams would help too. Thanks.
