Did some trainwatching today... the local Canadian National yard was pulling together a train with two SD75I's in a consist, and a third one that looked like it was about to be put into service. I know that Kato makes the SD70Mac, but the SD75I's seem to be a variant with some differences in the body. How much scratching and bashing might be needed to produce at least a reasonably accurate SD75I model in N-Scale. Here's the SD70Mac unit from Kato in BNSF colours: Here's an example of the SD75I in the red and silver BNSF colours: And finally, the CN SD75I that could be something to model after: Thoughts? Is it enough to start with an undecorated SD70Mac shell?
