Work began on the 8 km (5 mile) double track Connaught Tunnel in August 1913; the first train passed though 9 December 1916, with regular service beginning 4 days later. Because of the grade, west-bound traffic required extra "pusher" locomotives. In November 1958 the Connaught Tunnell was converted to single-track operation, and in July 1982 contracts were awarded for construction of the 14.6 km (9+ mile) reduced-grade Mount MacDonald Tunnel through Rogers Pass, to pass 91 metres beneath Connaught Tunnel (a total of 349 metres below the summit of Rogers Pass), for use by west-bound trains. Connaught Tunnel dedicated to east-bound rail traffic upon completion of Mount MacDonald Tunnel in (September ?) 1987.
