an hour on the journey. The official opening of the $ 422 million tunnel was in May 1989. The crest at the west portal is 90 metres (295 ft) lower than the Connaught crest. The 0.7% gradient westward eliminated the need for pusher locomotives. Nowadays, locomotives can climb the grade at 32 kilometres per hour (20 mph). Loaded coal trains travel at 14 to 21 kilometres per hour (9 to 13 mph) through the tunnel. To ensure frequency vibrations do not cause damage to the track structure, the speed limit for all traffic is 48 kilometres per hour (30 mph).

By mid-October, sufficient room existed to install their 6.7-metre-diameter (22 ft), 18-metre-long (60 ft) tunnel-boring machine (TBM). In December 1985, the tunnel passed 110 metres (360 ft) below the Connaught one, almost directly beneath the mountain peak. On completion, Selkirk Construction had advanced 8.45 kilometres (5.25 mi) westward. 731: 771:
is 7.9 metres (25 ft 10 in), and the width is 5.2 metres (17 ft) on the straights, and 5.5 metres (18 ft) on the curves. In September 1988, the final track concrete was poured. The paved concrete track (PaCT) rests on a 2.4-metre-wide (7 ft 10.5 in), 230-millimetre-thick (9 in) reinforced concrete slab. The height clearance can accommodate any future electrification.

Although monitored at the Revelstoke control centre, the ventilation system is computer controlled, and adjusts to the type and size of train. Standing at the top of the shaft, near the 250: 787:
Because of the tunnel's length and lack of electrification, it uses a ventilation system consisting of a series of huge fans which clear the tunnel of diesel exhaust left behind by the locomotives. The tunnel also has large doors at the portals and the mid-point which can open and close whenever the

alone could not meet the increasing traffic demands. The major growth opportunities were primarily in the bulk commodities of coal, sulphur, and potash. In 1980, the estimated construction cost of $ 300 million was almost 20% of CP's gross income for 1979. Furthermore, westbound grain transportation

On November 9, 1988, the first official train travelled the Macdonald Track westward. About 535 metres (1,755 ft) west of the west portal, R.S Allison, CP president, connected the last track clip. On December 12, 1988, the first revenue train, hauling coal, passed through the tunnel, and saved

CP repairs 15 to 61 metres (50 to 200 ft) of PaCT each year. Drain holes cored down to a longitudinal collector drain under the tunnel reduce failures from excessive surface water. Slab cracking, owing to insufficient lateral and longitudinal reinforcing in the PaCT slab, can be repaired with

The purpose of the ventilation system is to prevent locomotives overheating and remove air pollutants. The opening and closing of the gates at the portals and mid-point assists the extraction process. The mid-tunnel gate structure stands inside a 25-metre-long (82 ft), 27-metre-high

The hardware for power, communications, and signalling is obsolete. The slow ventilation systems can take 45 minutes to purge the air after each train. In 2019, consultants were advising on possible improvements, but it will probably take 5 to 10 years to modernize the tunnel.
