Matt (saintjohnrailfan) posted several videos of CN 405.
Here's CN 405 on May 31 with CN 2692, 2696 and BC Rail 756 in Rothesay.
I like this shot of the same train near Hampton. The track runs along the highway and you get a nice side shot.
Here's 405 on June 4 near Courtenay Bay in Saint John and by the E&NA station in Rothesay with 2502, 6135 and 2650 for power. In the Rothesay segment you can see two blocks of gypsum cars on the train - one to Belledune (from Irving Wallboard) and one to Nova Scotia (from McAdam).
Here's a late CN 405 on June 5 coming back light from Courtenay Bay.
The same 405 on June 5 at Tennis Court Road in Rothesay.
