The bridge grants a nice straight view along the westward tracks and you get a head-on type of shot of the oncoming eastbound units. I usually shoot from Main Street on the bridge over the station but thought I'd shoot at track level for this one.
VIA 50 / 52 is a connected pair of trains that head to Montreal and Ottawa. They depart together from Toronto and then separate in Belleville. It makes a few stops along the way but not at this station so it has time to pick up speed before blowing through on it's way toward it's first stop at Guildwood station.
On this morning 50 / 52 was a few minutes late. Waiting on a bench I caught sight of it's lights far down the track and positioned myself against a post, using it to help steady the camera. The train was on the center track of three and my view is straight down the middle, it's a quite warm morning and the heat is eminating from the surfaces as it approaches. Since I'm staying focused on the viewfinder and pointed westward, and it's noisy, I'm unaware of a GO express from Oshawa bearing down from the east on the track immediately to my left.
Trains, being rather large, displace a fair amount of air. One train moving in open air pushes it out and up and draws some along with it as it goes. Two trains in opposite directions and both moving quickly gives some additional dynamics to the whole process. Have it occur under a bridge adds jan extra element. Thus as I'm anchored to this post, VIA zips by on center track and at the same moment the express GO blows past me from behind. A brief but violent swirl of air throws the viewfinder of the camera shut, immediately terminating my recording. I quickly reopen the panel and feverishly hit 'record' until it started up again. It would have been a good clip had it all been a single shot. Unfortunately I ended up with two scenes and had to blend them together in editing, making the GO passing seem oddly brief.
Anyway, here's the outcome. All part of the fun.
