When shopping around for locomotives, this one caught my eye. Walthers has a huge selection of GP9M's, in many liveries. CP livery is done better then CN IMHO. So I bought it, primarily for switching and transfer duty. Here it's sititng at the station along with an IHC BN C-Liner, awaiting their crews. A consist like that should tell you the RR is powershort!
PS. While shopping around, I had a very hard time finding a picture of this unit, not a drawing, as posted in the Walthers catalog. Hopefully this solves the problem for those considering it. Did I mention it runs great?
