Bulldog Tunnel

The Bulldog Tunnel, which carried the former Canadian Pacific Railway (CP) southern main line under Bulldog Mountain, is in the West Kootenay region of southeastern British Columbia. By rail, the tunnel was northeast of Grand Forks, and west of Castlegar.

Name origin

The first appearance in print of the Bulldog Tunnel name was 1899, and of the mountain, from which it derived, occurred the previous year. The post office at Brooklyn, which closed in 1900, was to have relocated to the tunnel vicinity, but no evidence suggests this happened. The location is sometimes called the Coykendahl Tunnel.

Contract awarded

In May 1898, CP awarded the West Robson– Midway extension of the Columbia and Western Railway (C&W) to Daniel Mann, Foley Bros., and Peter Larson. The Bulldog Tunnel, the largest subcontract, was given to McLean Bros. This drilling and blasting bore would link the valley of Pup Creek with the Dog Creek drainage. The specified tunnel height of , and width of , required the removal of of rock. During construction, a temporary route with switchbacks carried the line over the mountain.

Construction

In July 1898, McLean Bros commenced work on the longest tunnel in BC at the time. Three 80-hp steam boilers were shipped in to power the two air compressors supplying 14 drills. A full complement of employees did not arrive until October. However, a limited water supply allowed only one boiler to operate, restricting operations to four rock drills. By January 1899, only of the tunnel had been completed. By April, the rail head was nearing the eastern portal of the tunnel. In June, when a brush fire reached the gunpowder magazine, workers fled to the safety of the tunnel. The explosion damaged several buildings, twisted the railway track, and felt like an earthquake at Brooklyn, away. That same month, McLeans abandoned the project, while the tunnel was less than a third advanced. Replaced by Olaf Olsen, progress improved. By mid-summer, tracklayers had upgraded the temporary narrow gauge Bulldog switchback track with temporary standard gauge switchbacks.

With Brooklyn largely deserted, the tunnel location provided the only viable commercial opportunities in the area. In August, a store was established. In September, two tunnellers were asphyxiated by toxic gases on entering too soon after blasting. That month, the hotel at the switchback summit closed, and mail carrier Frank Corte opened a hotel a half mile below the tunnel. Also, the Grand Forks–West Robson passenger service commenced. Immediate stations were Summit (renamed Farron) (Mile 36.8), Tunnel (West End) (Mile 44.3), Tunnel Summit (Mile 47.1), Tunnel (East End) (Mile 50.0), and Shields (Mile 60.2).

The switchbacks took an hour to negotiate. In November, a westbound passenger train derailment on the switchback caused a three-hour delay. By that time, the tunnel had progressed from the west portal, and from the east portal. In December, an eastbound freight train wrecked, killing a freight hopper. At month end, the approaching tunnels met. In February 1900, the first train cleared the tunnel, passing below the former switchback summit. No longer needing to split the cars, the time saving for freight trains was far greater than the one hour gained by passenger trains. The next month, the Corte hotel closed.

Operation

Tunnel station was west of Coykendahl, and east of Porcupine, and east of Farron. The locals designated the passenger service on the southern main line as the Bulldog Express. Snowslides and rockslides were common in the tunnel vicinity.

In 1900, a brakeman fell under the wheels of a freight car at Farron, resulting in the later hospital amputation of his leg. In 1902, the high Porcupine bridge burned down. During the 10-day rebuild, passenger trains terminated at either end, and passengers transferred. In 1909, a passenger train stalled in the tunnel. In 1918, a snowslide near Coykendahl derailed a train.

A 1931 forest fire destroyed the CP section house and bunkhouse. In 1935, 64 relief camp strikers, who were freight hopping westward, were arrested on a train at Coykendahl and jailed in Nelson. In 1938, a Renata trapper froze to death after leaving the train and becoming lost. Renata residents accessed the Tunnel flag stop along a trail.

In 1952, eight cars of an eastbound freight train derailed at Coykendahl.

Passenger services on the southern mainline ended in January 1964.

Repairs & maintenance

In 1912, a section crew standing on a handcar was removing icicles at the tunnel mouth. An approaching train fatally injured a member who was attempting to remove the handcar from the track.

In 1918, shortly after a freight train exited the tunnel, water seepage in the roof caused about to cave in at the east end. During a five-day closure, two passenger trains diverted onto the Great Northern Railway (GN) track, and travelled via Marcus, Washington. Later trains served intermediate points in BC.

In 2016, to address tunnel roof instability caused by rotting heavy timbers, shotcrete was applied, and rock bolts and overhead rock mesh installed.

Abandoned & repurposed

In 1991, the CP track was abandoned westward in its entirety, and eastward almost to Castlegar. The section from Castlegar to Grand Forks is now a rail trail that includes vehicular access. The tunnel interior is pitch black, especially noticeable when travelling westward, because of a curve at the western end.
