It’s
been a rough few months for rail safety, with any number of horrific crashes
and derailments causing death and injury around the world.
Meantime,
one of Spain’s famous AVE high-speed trains literally flew off the tracks on a
sharp curve, killing 79 passengers… two French commuter trains
collided in a
station… and the small town of Lac
Megantique Quebec was turned into a deadly inferno when
unattended tanker cars rolled down a hill and explode. What’s going on here and what can be done to
prevent these kinds of incidents?
I’m
no expert on the engineering of railroads, so I’ve spoken to several people who
are; what they’ve told me is both reassuring and frightening.
SAFETY: Trains,
whether passenger or freight, are still extremely safe. When accidents occur, the damage can be horrific
which makes for great television. But
the stats are that you’re
four times likelier to die in a bus crash and 28 times likelier to die in a car
crash than on a train.
STANDARDS: US
rail cars are manufactured to much higher safety standards than European or
Asian trains. The Federal Railroad
Administration sets standards of survivability based on “crash worthiness”
while the foreign systems aim for “crash avoidance”. Of course that means our trains are heavier
and less fuel efficient, especially at high speed. But they’re built with crumple zones, like
your car.
ACELA: Amtrak’s
Acela is hardly the fastest train in the world, but a former FRA member told me
he thinks it’s the “world’s safest for crash worthiness.” Before Amtrak ordered the bespoke train sets,
they brought over a Swedish tilt-train (the X-2000)
and Germany’s ICE trainset to demonstrate the potential of high-speed trains between Boston and Washington. I had a chance to ride both, but while they garnered great PR for Amtrak, neither of the trains (among the best in the world for the time) met US safety standards, then or now.

TESTING: All
new US rail equipment is put through rigorous testing at an FRA facility in
Pueblo Colorado, a giant race track for trains.
Trains are tested for speed, acceleration and braking as well how they
operate in extreme heat and cold. Amtrak
is now testing
new locomotives at the facility prior to their deployment on the Northeast
Corridor.

PREVENTING HUMAN
ERROR: When
a train engineer is on the phone, texting friends or ignoring his professional
duties, there should be technologies that can intercede. After a fatal MetroLink commuter
train crash near LA in 2008, the FRA mandated that all railroads install “Positive
Train Control” by 2016. The system of
signals, sensors and automatic train controls will cost the railroads $22+
billion. A former senior FRA official,
speaking to me on background, said the system is a desirable goal but “completely
unattainable” by the current deadline due to lack of money and technology.
TANKER CARS: Unlike
other freight cars which are owned by the railroads, tanker cars are owned by
the shippers. They often carry propane,
chemicals and fertilizers, some of which can be lethal if spilled (anhydrous ammonia, chlorine). Yet, because the railroads are “common
carriers” they must carry these shippers’ cargoes, even though they have no
control over the safety standards of the tanker cars carrying them. As a former railroad official told me, “if
these chemicals aren’t being carried by rail, they’d be on the highways”, where
accidents are much more common.
Travel
and transport by rail is already safe. But
we must have the will and find the ways (money!) to make it even safer.
