What's interesting to me, unless my visual reading of the CN one is mistaken, the cab seems to have a flat section in the center of the roof, while the UP one Terry posted does not. Also, the pattern of windows in the front of the cab looks different. I would think the UP version could be bashed from an SW-7 or SW-1200, at least getting a reasonable facsimile; the CN one looks like it might require a bit more work to get the details right.
I think you did a very sneaky delete and replace there Terry.
