QUOTE: Originally posted by BentnoseWillie CP have owned neither SD50's nor SD70's. They went straight from the SD40-2 and SD40-2F (the latter with a unique-to-CP cowl carbody) to the SD90MAC and AC4400CW. Soo Line - a CP subsidiary - has SD60's and SD60M's, and I presume these will eventually wear CP paint, unless they're sold. CN have SD50F's and SD60F's (with cowl carbodies), as well as SD70I's and SD75I's. The 50's and 60's are available as resin kits from Kaslo Shops, and the 70's and 75's in RTR form from Athearn.
