 Safety officials have championed what's known as positive train
control technology for decades, but the railroad industry has sought
to postpone having to install it because of the high cost and
technological issues.
Investigators haven't yet determined whether the weekend wreck,
which killed four people and injured more than 60 others, was the
result of human error or mechanical trouble. But some safety experts
said the tragedy might not have happened if Metro-North Railroad had
the technology, and a senator said the derailment underscored the
need for it.
"This incident, if anything, heightens the importance of additional
safety measures, like that one," said U.S. Sen. Richard Blumenthal,
a Democrat from Connecticut, which also is served by Metro-North.
"I'd be very loath to be more flexible or grant more time."
The train was going 82 mph as it entered a 30 mph turn Sunday
morning and ran off the track, National Transportation Safety Board
member Earl Weener said Monday. He cited information extracted from
the train's two data recorders; investigators also began
interviewing the train's crew.
The speed stunned officials — "I gulped," said U.S. Sen. Charles
Schumer, D-N.Y. Gov. Andrew Cuomo said the NTSB findings make it
clear "extreme speed was a central cause" of the derailment and
vowed to "make sure any responsible parties are held accountable"
after investigators determine why the train was going so fast.
"At this point in time, we can't tell" whether the answer is faulty
brakes or a human mistake, Weener said.
Weener sketched a scenario suggesting that the throttle was let up
and the brakes were fully applied way too late to stave off the
crash. He said the throttle went to idle six seconds before the
derailed train came to a complete stop — "very late in the game" for
a train going that fast — and the brakes were fully engaged five
seconds before the train stopped.
It takes about a quarter-mile to a half-mile to stop a train going
82 mph, according to Kevin Thompson, a Federal Railroad
Administration spokesman.
Investigators are not aware of any problems with the brakes during
the nine stops the train made before the derailment, Weener said.
Weener would not disclose what investigators know about the
engineer's version of events, and he said the results of drug and
alcohol tests were not yet available. Investigators are also
examining the engineer's cellphone; engineers are allowed to carry
cellphones but prohibited from using them during a train's run.
The engineer, William Rockefeller, "is totally traumatized by
everything that has happened," said Anthony Bottalico, executive
director of the rail employees union.
"He's a sincere human being with an impeccable record that I know
of. He's diligent and competent," Bottalico said. Rockefeller, 46,
has been an engineer for about 11 years and a Metro-North employee
for about 20, he said.
Positive train control, or PTC, is designed to forestall the human
errors that cause about 40 percent of train accidents, and uses GPS,
wireless radio and computers to monitor trains and stop them from
colliding, derailing or going the wrong way. The transportation
safety board has urged railroads to install PTC in some form since
1970, and after a 2005 head-on collision killed 25 people near Los
Angeles, Congress in 2008 ordered rail lines to adopt the technology
by December 2015.
Metro-North has taken steps toward acquiring it but, like many rail
lines, has advocated for a few more years to implement a costly
system that railroads say presents technological and other hurdles.

Grady Cothen, a former FRA safety official, said a PTC system would
have prevented Sunday's crash if the brakes were working normally.
And Steve Ditmeyer, a former FRA official who teaches at Michigan
State University, said the technology would have monitored the
brakes and would not have allowed the train to exceed the speed
limit.
"A properly installed PTC system would have prevented this train
from crashing," he said. "If the engineer would not have taken
control of slowing the train down, the PTC system would have."
The Metropolitan Transportation Authority, which runs Metro-North,
began planning for a PTC system as soon as the law was put into
effect, spokeswoman Marjorie Anders said. After some early-stage
work such as buying radio frequencies, the MTA awarded $428 million
in contracts in September to develop the system for Metro-North and
its sister Long Island Rail Road.
But the MTA has advocated for an extension to 2018, saying it's
difficult to install such a system across more than 1,000 rail cars
and 1,200 miles of track.
"It's not a simple, off-the-shelf solution," Anders said Monday.
On Sunday, the train was about half full, with about 150 people
aboard, when it ran off the rails while rounding a bend where the
Harlem and Hudson rivers meet. The lead car landed inches from the
water.
The dead were identified as Donna L. Smith, 54, of Newburgh; James
G. Lovell, 58, of Cold Spring; James M. Ferrari, 59, of Montrose;
and Kisook Ahn, 35, of Queens.
Some of the injured remained hospitalized Monday, including seven in
intensive care at one hospital and two patients in critical
condition at another.
The train was configured with its locomotive in the back instead of
the front. Weener said that is common, and a train's brakes work the
same way no matter where the locomotive is located. Ditmeyer said
the locomotive's location has virtually no effect on train safety.
Still, some people feel the configuration provides less protection
for passengers because if the train hits something, there's no
locomotive in front to absorb the blow, said Bill Henderson,
executive director of the Permanent Citizens Advisory Committee to
the MTA, a riders' advocacy group.
The derailment came amid a troubled year for Metro-North, and marked
the first time in the railroad's 31-year history that a passenger
was killed in an accident.
In May, a train derailed in Bridgeport, Conn., and was struck by a
train coming in the opposite direction, injuring 73 passengers, two
engineers and a conductor. In July, a freight train full of garbage
derailed near the site of Sunday's wreck.
