The NBEC/CFMG SD40 units are still running on the mainline freights on the former Quebec Railway Corporation territories. Here are two videos from NBEC69 and one from David Chiasson. First, NBEC69's videos.
On Sunday December 7, CFMG 6903, NBEC 6905 and CN 5260 ran through Rimouski.
The same units again, in a different location.
Finally, because I love them so much, here's David's video showing NBEC RS-18s 1866 and 1814 powering the ore train through Nepisiguit Junction back on May 6, 2007. Listen to the squeal of metal on metal as they go through the curve!
