Comments on: CN S13 units 8611 and 8621 bracket slug B7 on a hump set, working the Toronto Yard (later renamed MacMillan) hump on the pullback track north of Rutherford Road overpass. Two fresh-looking Dupont Canada anti-knock compound tank cars are coupled near the head end. When the yard opened, they used S13-slug-S13 sets designated in an H1-H2-H3 configuration, where H1 was the main unit outfitted with hump control, radio and signal equipment, H2 was the slug (converted from retired S3 units) and H3 was a trail-only unit with no special equipment aboard. The 8600′s were a slightly heavier duty specified S13 than the 8500′s, equipped with GE 752 traction motors, full automatic transition, MU, 26L brakes and extra weight. This area of Vaughan (the old hamlet of Maple/Sherwood) was still very rural at the time, with no Canada’s Wonderland or housing developments visible north of the yard. The farm and old stone farmhouse at the upper right was about where Seafield Road is today (suburban neighbourhood built in the 90′s), and the farm and barns in the distance were way up at Major Mackenzie and Jane Street (southwest corner, where the Fortinos plaza is today).

They are just like the Dupont (anti-knock/tetra-ethyl-lead) cars we unloaded at the IOL refinery in Edmonton. And of course, what went with the anti-knock compound, anti-knock engines. Fancy engines that were used at the refinery. By the way they pinged, this would tell you that the additives and blends were in the right ratios or not. :-) Cool, haven’t seen those tanks in a while.
