Caption: What better advertisement could you have for your commuter service than sleek passenger trains speeding past drivers sitting in bumper-to-bumper traffic on the highway? GO Transit cab cab 9851 trails a 9-car train of single level Hawkers at Sunnyside, travelling inbound to Union Station behind one of GO's unique GP40TC units. Heading in the opposite direction is evening rush-hour traffic inching its way out of downtown Toronto on the Gardiner Expressway.

As well as the usual 70's automotive potpourri for those so inclined (I spy a Pinto), mixed in the congestion is a Mack DM-series cement mixer for Premier Building Materials, a pair of Dodge (or Fargo?) LCF van trucks, and two IHC Loadstars mixed with a Ford C-series (operator names not entirely visible).
