Unfortunatley, I don't think they will be around forever, at least on CP. As far as I can tell, they stopped overhauling them quite a while ago...I'd be glad if someone proved me wrong, but has anyone seen one in fresh paint recently? They have already sold/retired, and even scrapped quite a few, which one would have thought they would never do, given the love affair they have had with them for pushing 4 decades. The ones I see in the west, all too infrequently now I might add, are pretty rough for the most part. They were THE power for so long, many years after being bumped from that position on most other railways, and have been worked very hard for many years(in true CP style), They are probably getting quite worn out now. Even then though, I still believe CP will one day regret the switch to GE, There is no way they are going to last 30+ years.
