Delivering Fuel Oil to the Connaught Tunnel
After a series of disastrous avalanches in Rogers Pass in the early 1900s
it was decided to construct a tunnel under Rogers. The planned tunnel
would cut the climb in half, shortened the distance by four and a third
miles and do away with curves (the loops) equal to seven circles.
The contract for the new tunnel was awarded in July 1913. Official
operation of trains through the five-mile-long, double-tracked
Connaught Tunnel under Rogers Pass began on December 9, 1916. To
provide greater clearances for oversized boxcars and tri-level auto
transporter cars, Connaught Tunnel was single -tracked early in
With the completion of the tunnel, the problems and hazards of
operation over the “High Line” through Rogers Pass, particularly
during the long, cold months of the Rocky Mountain winter, finally
Ventilating machinery was provided at the west portal, because the
top of the 2% grade westbound was only a few hundred feet inside the
tunnel from the western portal. Ventilation was designed not to suck
air out of the tunnel, but to force air into it against the ascending
trains, thereby blowing the exhaust gases back over the train. This
benefited the engine crew but was a hardship for the train crew. The
ventilating fans were not used when eastbound or downgrade trains
entered the tunnel.
A duplicate plant was installed consisting of two multi-blade fans
powered by diesel engines. The engines burned California crude oil,
which was the same kind of crude oil used by the oil-burning steam
locomotives of the Canadian Pacific, between Field and Vancouver,
British Columbia. Crude oil was delivered to a short siding to the right
of the west portal that accommodated one car.
Similarly, on John’s layout the siding rose steeply and was level
enough at the top to accommodate only one car.
Time required to complete: Approximately 1 hour 35 minutes.
