Officials: Life-saving train technology is rarely used
Los Angeles – — Nearly a decade ago, the U.S. secretary of transportation stood at the site of a horrendous commuter train crash near downtown Los Angeles and called for the adoption of a new train car design that testing showed could blunt the tremendous force of a head-on collision.
In response to that 2005 accident that killed 11 people, Southern California’s Metrolink commuter railroad bought new passenger cars equipped with these “crash energy management” systems.
On Tuesday, that investment appeared to have paid off when a Metrolink train smashed into an abandoned truck in a crash remarkably similar to the 2005 wreck.
This time, three of the four double-decker passenger cars had the technology. Of the 50 people on board, only eight were admitted to hospitals, even though the impact at an estimated 55 mph was violent enough to fling several of the cars onto their sides. No one died.
“Safe to say it would have been much worse without it,” Metrolink spokesman Jeff Lustgarten said of how the technology performed during the crash in Oxnard, about 65 miles northwest of Los Angeles.
And yet the technology is not widely used in the United States. And while federal regulators have for years weighed rules that might require it, they have not formally proposed such measures.
Aside from Metrolink, crash energy management equipment is used by Amtrak, including on its Acela line in the Northeast, and two systems in Texas, according to the Federal Railroad Administration.
Such systems can vary in design, but the general idea is to disperse the energy of a crash away from where the passengers sit. Metrolink’s cars have collapsible “crush zones” at the ends of its cars that help absorb the impact, along with shock absorbers, bumpers and couplers.
It is the same principle at work in the “crumple zones” in newer cars. They are designed to absorb the force of a crash while keeping people inside safe.
One obstacle to more widespread use of the train technology is that it has to be designed into new passenger cars, and railroads that bought cars without it in recent years may not want to invest in new ones so soon. Railroads can’t simply retrofit existing cars.
“It is not a bolt-on device,” said Martin Schroeder, chief technology officer for the American Public Transportation Association.
