Caption: I didn't have a train # written down for this train but the three reefers on the head end and the day of time should make this #410. The three reefers were the remnants of what even a short time before was often a long block of reefers on the head end of #410 that would be set off at Aldershot for forwarding to the Ontario Food Terminal. Trailing the "shiny new" GP40-2s up front are a pair of GP40s briefly escaping duty as "tunnel motors" pulling trains between Sarnia, ON and Port Huron, MI back in the day before runthrough power through the tunnel.
