A variety of CN's switchers - from S-13s to SW1200s to Geeps - at work in the Canadian Maritimes. You'll see them working at the Halifax, NS autoport, the Dartmouth, NS waterfront, and around the Gordon Yard in Moncton, NB.
This video was uploaded by Steve Boyko after David's death, on the request of David's widow Pat. She wants to share David's work with everyone. Apologies for any errors or omissions in the captions.
This video was recorded using a camcorder on VHS videotape and then digitized, so the quality is not as good as David's later work.
