Caption: This is likely, but not necessarily an eastbound Clover Bar Transfer (Calder to Clover Bar Yard) beginning the crossing of the North Saskatchewan River in NE Edmonton. The units are re-trucked GMD-1's. They were to become very common for switch in transfer duties in Edmonton. The need for the 1A1 trucks in the Edmonton area (and likely system wide) was diminishing at this time. Those telegraph cable outriggers on the bridge would be removed sometime around 1991 when CN decides to rid the landscape of the poles and cables.
