Before I start, I am aware of Eyein12's GP60M being an already existing option for anyone who wants this locomotive, but I feel that the modeling on his is a bit off from the original. It kind of lies in an uncanny valley of looking close to the original, but being just 'off' a little bit. It may just be me being a sucker for little details, but it is kind of off-putting for me. This is not meant to be a rant about Eyein12 doing a bad job, I hope this can be seen as a honest critique of his work. OK on to the topic at hand: The EMD GP60M was a special variant of the GP60 with a wide cab design, making it the only wide cab GP series locomotive built for a US customer. The GP60B was a cabless variant of the GP60, making it the newest cabless EMD since the GP30B. Both of these variants used the 16 cylinder 710G3A prime mover making 3,800 horsepower, and had a B-B wheel arrangement. Both of these special GP60 variants were built as a special order from the Santa Fe for their new "SuperFleet" locomotive fleet, being delivered in 1990. They were to be used in high-speed intermodal service along with the GE B40-8W's, which were also exclusive to the Santa Fe. The GP60M's and GP60B's would be used in this role throughout the 1990's, through the end of the Santa Fe and into the BNSF era, where they would be gradually put into local service through the 2000's. in the early 2010's, BNSF would begin overhauling their GP60M fleet to be more efficient, these rebuilds would be called GP60M-3's. BNSF still owns most of the GP60B's they inherited from the Santa Fe, with some being rebuilt with cabs. These 2 unique locomotives would be a great addon to Train Simulator because there is a definite lack of Santa Fe content beyond the SD45-2, and Raton Pass, so this locomotive could expand the range of Santa Fe and BNSF content to choose from. The locomotives could come with scenarios for routes like Raton Pass, Pacific Surfliner, Marias Pass, or Cajon Pass (maybe too old). Below are pictures of both GP60M's and GP60B's in possible paint schemes that could be included.
