I timed it on Sunday morning to catch train #643 on exit. I had little time for neither running nor fanning so I had to keep my wait period down to a minimum. I arrived about 5 minutes before departure and had enough time to pick an angle and focus points. The trail pathway is however on the northerly side of the tracks which means you don't get a direct sunlit view on departure. Trains will get full sun once they round the bend and turn southward so the morning sun catches them full side, as seen in the Youtube thumbprint.
For this morning, 643 was lead by F40PH unit #6455. I believe the parked unit on the right is #6415 but hard to tell in the shot hear, the original 1080 vid reveals the numbers a bit better but I'm still not positive if it's 6415 or not.
The departure is quite slow. The train doesn't start to throttle up until it rounds the bend so it's a fairly quiet pass. Next time I'm in the area I'll venture down line a bit, there are some level crossings further south that should offer good views and units at higher power output.
