2 rebuilt F40PH-3 locomotive's are in the lead of trans-continental VIA #1, also known as 'The Canadian', which crosses Canada from Toronto en-route to Vancouver. This shot is usually very rare to come across as #1 usually departs Toronto (about 45 minutes away for #1) at 22:00, making it pass through this location on the York Subdivision at nearly 23:00. However, since the last days inbound VIA 02 got in so late (past 22:00 for those wondering), #01 had to be rescheduled for a 08:30 departure out of Toronto the next morning. Here they are doing 45mp/h on the York Sub hurrying to make up at least some of their delayed time into Vancouver.
