Reliving history... SD40-2 CP 5743 is spotted leading a CP 2-135 under the clyde bridge at mile mark 55. 5743 is one of the few remaining SD40-2s in service in CP's locomotive roster. It's truly astonishing seeing these old guys leading mainline freight trains in today's day and age with the new technologies like the GE series and the oncoming rebuilds of older units. Absolutely breathtaking!
