This past Sunday, myself and Dave (http://www.youtube.com/nbsrfan) decided to chase 406 west from Sussex to Saint John, NB.
We met up just east of Sussex. About 15 minutes later, the train came by, with CN 2159 on the point.
Afterwards, we gave chase. The first shot is from the Odell Loop Rd crossing, near Bloomfield, NB. The second "chase" shot is following along with it outside of Hampton. We were lucky to be able to keep pace with it, especially with all the Sunday drivers. The last shot is from Renforth, a few miles outside of Saint John, NB. All three shots in the chase are together in one video.
It's been awhile since I've done a chase of this train, so I figured it was time. I'll probably end up doing this more once the weather warms up a bit.
