Caption: Before purchasing any AC-drive locomotive (other than pioneer M640 4744), CP assessed what high-powered DC units were on the market by borrowing from other railways, and in the winter of 1990-1991 tested a near-new trio of Union Pacific GE Dash8-41CW units on grain trains between Calgary and Vancouver terminals, seen here as UP 9416+9413+9409 on 1991-03-03 with westbound loads in the siding at the west switch of Yale, BC, at 1531 PST in a snowstorm, meeting an eastbound with three SD40-2s CP 5861+5666+5676 and grain empties. PK okay, have a good trip.
