Caption: Via Rail MLW locomotive FP4A 6789 leads MLW FPB4 6867 onto the turntable at the old Via roundhouse on a hot summer day in August of 1983, back when roundhouses were still a thing. All of this is changed nowadays, although I am told you can visit a great museum and get food and ale at the former CP John Street location. Note the sign stating, "All units must stop before coming on turntable.' They indeed did stop on that day, way back when.
