I understand these units were not equipped with dynamic brakes. I also read somewhere this limited their use to east of The Rockies. Can anyone confirm this?
I saw CP1800 pulling The Canadian at Montreal West station in about 1955. It was westbound at the time and was the only power unit. Doesn't necessarily mean it was the locomotive that was pulling it all the way to Vancouver though.
CP 1800 had a long life. Seems it spent most of its time in Edmonton in its later years working for VIA. Again though, did the lack of dynamics keep it east of the mountains?
