CSX inherited this trackage from Conrail after the split in 1999. Former Conrail "Montreal Secondary" became the "St. Lawrence Subdivision" and the Conrail "Montreal Branch" became the "Montreal Subdivision" under CSX. Headed north, after crossing the Seaway into Canadian land, the tracks are in Quebec, not Ontario.
Here's some photos from one of my recent trips up to Bear Mountain, NY. For best viewing press the 'Slideshow' button in the upper right-hand corner of the screen and then clear the checkmark from the 'Auto-show' box so that the caption box doesn't interfere with the pictures.
