New YouTuber JamminJoel has put a few videos up.
This one from January 13 2007 shows the NB Southern eastbound train at the highway 630 crossing, just on the New Brunswick side of the Maine border. NBSR 9802, yellow 2317, green 2319 and 9801 supplied the power for a decent-sized train.
The train continued on with NBSR 2318 added. Joel shot it at Harvey Station by the highway crossing.
He also has a few CB&CNS videos up... check them all out. Here's one from November 3, 2006.
