The summer of 2009 I spent wandering Alberta and British Columbia and, already, so many of those images are not to be repeated and can be considered "classic". I caught the tail end of BCOL leading on BCOL before the locos were freed up for leading elsewhere on CN. This northbound move came at first light, but was late. Got very lucky as its counterpart was the only other scheduled train on the line and it, too, ran at night....on this day, turning south with the same set of power, BCOL leading.
