The 14.6 km (9+ mile) Mount Macdonald Tunnel is located below the Connaught Tunnel through Rogers Pass, and is the longest railway tunnel in North America; its' reduced grade now allows freight trains to travel from Calgary to Vancouver without the need for the extra "pusher" locomotives that had to be used in the old Connaught Tunnel. The Macdonald Tunnel carries only west-bound rail traffic (east-bound traffic is routed through the Connaught Tunnel). See file G.2.32 (Oct 88) for detailed chronology of Rogers Pass, including the Mount Macdonald Tunnel project.
