Matt aka saintjohnrailfan posted a nice video of CN 121 leaving Moncton with CN 2405, 5530,and 5632. The train had a fair amount of non-container traffic on the head end. Nice to see a Dash-8 leading!
Dave aka nbsrfan was there and taped the same train. Here's Dave's video of CN 305 and 121. I'm not sure I like the 30 second intro but you can skip past that. ;)
