Caption: To connect traffic off CN’s Great Slave Lake line from Hay River and Pine Point to the rest of the railway network, Northern Alberta Railways ran a GSL Turn from McLennan to CN’s Roma Junction yard near Grimshaw then back to McLennan, and acquired four SD38-2 units with dynamic braking to handle the grades down to and up from a crossing of the Peace River at the town of the same name. Here, a trio (typical power on a GSL Turn), 402 + 403 + 401, is well into the ruling grade southward from Peace River heading back to McLennan.
