EMD used some of the extra front porch on the SW1 to add a utility box. The NW2 already had a box behind the cab, so the increase in the size of the back porch on the SW1 is really noticeable. As it was, it was relatively easy to produce a pseudo SW1 from the cast NW2 by simply shortening the front hood. This is what All Nation did with their short-lived 600-Hp model. To produce a more accurate SW-1 from the All Nation shell, the hood has to be shortened and the hood and cab must be cut away from the frame and moved forward. I have seen two models so modified:

I do not know the original builder of the NYC unit, but Brian Scace rebuilt it at one point following an unfortunate shipping damage incident. The OPS model is the fine work of John Fisher. OPS stands for Ohio Public Service, an actual railroad in the Toledo area seen by John in his youth. As far as I can tell, OPS never had an SW1 (or perhaps any other diesel). I have so far resisted the temptation to re-letter it for the Milwaukee Road, but that may happen someday.
