Three years after two railway workers were killed in a crash near
Lillooet, BC, a Transportation Safety Board report has linked CN Rail's
practices for several serious accidents since the company took over BC
Rail. That takeover, part of the Campbell Liberal government's sellout
of public assets to private interests, remains highly controversial.
The stench of corruption lingers over the deal, reaching into the
Premier's office, but the judicial inquiry into the sale has taken so
long that many voters paid little attention to the scandal during the
recent provincial election campaign.
Released on May 28, the TSB report suggests
that imposing CN's
operating practices onto BC Rail, and the failure to follow its own
safety rules, were factors in several accidents.
The report blames the June 2006 crash on CN
Rail's decision to
switch to locomotives with an inadequate braking system following the
takeover. Ignoring employee concerns, CN did not carry out a risk
assessment before replacing BC Rail locomotives equipped with "dynamic
braking". Instead, the company changed to older locomotives equipped
with friction brakes.
"Dynamic braking" is designed to limit the
speed of a locomotive
going down steep grades, which are extremely common in British
Columbia. Friction braking uses only the friction of brake shoes on
wheels, a design suitable for the prairies, but not on mountain
inclines.
The Lillooet crash involved a four-axle
switching locomotive and
one fully loaded lumber car, each weighing about 130 tons, descending a
steep grade. When the crew could not slow the train using the
locomotive brakes (the car air-brakes were found to be not operating
properly), they applied emergency brakes and decoupled the lumber car.
The conductor climbed up to make his way to the lumber car's hand brake
at the far end, but the car derailed on a sharp curve while travelling
at about 80 kilometres per hour, killing the conductor. Travelling even
faster, the locomotive left the rails on another sharp curve, sliding
down a mountainside. The trainman was killed, and the engineer was
severely injured.
The TSB says the accident could have been
avoided had the
locomotive been equipped with dynamic braking. The report also says
that when CN Rail made its switch, no consideration was given to the
steep grades on the line, and no formal risk assessment was done.
Four CN main-track derailments occurred on the
Squamish
subdivision south of Lillooet between August and December 2005. The
most serious was in August 2005, when a long, heavy train derailed on a
sharp curve, spilling 40,000 litres of caustic soda into the Cheakamus
River, causing enormous losses to the fish population.
"Peeling back the layers of the onion, the
fact that this business
decision was taken to remove locomotives equipped with a supplementary
braking system from this territory becomes particularly important," Dan
Holbrook, Western Canada manager of the TSB's rail-pipeline
investigations branch, told the Globe
and Mail. "We know the decision
was a financially motivated decision but what's important to the safety
board and from a safety-accident investigation perspective is that they
didn't perform the required risk assessment, required by their safety
management system before making this significant operational change,"
Holbrook said.
The company says that employee concerns were
not raised prior to
the Lillooet accident, a claim which was accepted at face value by the
TSB report but widely ridiculed by railway workers. CN has also claimed
a 31-per-cent reduction in main-track accidents between 2007 and 2009,
and a 29-per-cent reduction in non-main-track accidents.
But as one post to the Globe and Mail website noted,
"this
reduction is based on a highwater mark of a 75% increase in 2005. If
the accidents went down 29%, that is still a 46% increase over 2004."
Meanwhile, the Island Tides newspaper reports that
"It is rumoured
that on the fifth anniversary of the BC Rail sale (July 14, 2009), CN
can purchase BC Rail's waterfront lands for one dollar. No details are
available, because the documentation of the deal has never been made
publicly available."
