Congress Holds Hearing on Amtrak Crash

Officials testified at a congressional hearing on Tuesday about why a technology that slows trains wasn’t in place before last month’s derailment in Philadelphia that killed 8 people.

WASHINGTON — Federal regulators told Congress on Tuesday that they were still working to understand why an Amtrak train was traveling at double the designated speed when it derailed in Philadelphia last month, killing eight people and injuring about 200.

Investigators said during a hearing of the House Transportation Committee that they were examining several potential causes. The possibility of human error was a focus of the hearing, but the investigators said they were also looking into whether there had been any mechanical problems.

The train, en route from Washington to New York on May 12, was traveling at 106 miles per hour as it entered a curve where the speed limit was 50 m.p.h. Christopher A. Hart, the chairman of the National Transportation Safety Board, said the agency was continuing to examine data from the crash, as well as the cellphone of the train’s engineer, Brandon Bostian, 32.

Mr. Hart said that Mr. Bostian had given regulators the pass code to the phone and that the agency had access to its data. But he added that technological issues made it difficult to determine whether the phone had been turned on at the time of the accident. “It’s been far more complicated than we anticipated,” he said.

Several lawmakers expressed frustration at the pace of the investigation. “My concern is that N.T.S.B. made definitive statements after the accident, but here we are weeks later and they still can’t say what led to the accident,” said Representative Jeff Denham, Republican of California and the chairman of the committee’s railroad subcommittee.

Democrats and Republicans on the panel also clashed over whether funding shortfalls played any role in the crash. Representative Peter A. DeFazio of Oregon, the ranking Democrat on the committee, and others in his party repeatedly questioned whether Amtrak had enough money to carry out changes to make trains safer, including the installation of technology known as positive train control.

Mr. Hart reiterated the safety board’s position that the accident could have been prevented if positive train control had been installed. Amtrak has installed the technology in parts of the Northeast Corridor, which stretches from Washington to Boston. But the system, which can automatically slow or stop a train to prevent accidents, was not in operation on the stretch of track where the crash took place.

After a deadly commuter train accident in California in 2008, Congress mandated that the technology be installed throughout the nation’s railroad system by the end of this year. But that has proved to be a challenge both for railroads and regulators, in part because of the complexity of the technology, which provides real-time information to locomotives, engineers and train dispatchers about train speed and location. That allows trains to automatically respond to sensors placed along the tracks.

Congress is considering extending the deadline to 2020 at the urging of some freight and passenger rail systems.

Witnesses on Amtrak Derailment

Witnesses described the scene after a New York-bound Amtrak train derailed and overturned late Tuesday in Philadelphia, leaving some passengers dead.

AP bc2a7b83de9d432d8274d2114841e5f1 WPVI: COURTESY WPVI, EMBARGO PHILADELPHIA Philadelphia, Pennsylvania - 12 May, 2015 SOUNDBITE (English) Scott Lauman, Witness: “I was in the parking lot in the shopping mall here, heard kind of a loud kaboom, saw helicopters flying in. So I ran down here, I couldn’t see anything, so I jumped the fence, I went up on this bridge right here, this train bridge, and that’s when I saw, it’s this total chaos, I mean it’s just a travesty. There’s just trains everywhere. The engine was way off the track, probably 400 or 500 yards way off the track, and then about six or seven cars just followed it right down the hill. I think three of them are on their side, one of them is sticking straight up in the air, and it hit some telephone poles, so the telephone poles were down and the wires were down.” . “Slowly but surely, by the time I stood up there for about an hour, cops and firemen and helicopters just started coming in. But there’s no way, they can’t get any emergency vehicles to the people. Because on the west side of the tracks, there’s an old abandoned warehouse that blocks everything. And on this side of the tracks where you see all the people going in here, is a train yard with like four trains lined up. So there’s no way to get to the actual wreckage.” . “Well the people they were pulling out weren’t walking away from it. They were carrying them away on flatbeds, because like I said, it took a long time, they couldn’t even get any lights in there. The only lights they had was from the helicopters. Because like I said, there’s no way to get vehicles in there. Then that old abandoned warehouse, they finally threw a ladder up on there, and I saw a bunch of firemen go on top of the old abandoned warehouse and they set up spotlights down on the accident. So now they have a little bit more light.” // AP 55fef251ab29407697ebdfcd78c4204d Philadelphia, Pennsylvania - 13 May, 2015 SOUNDBITE (English) Paul Cheung, Train Passenger “And suddenly the train comes to a complete deceleration, as if someone has slammed the brake. The tains went dark and suddenly everything started shaking around. People were panicking, stuff was everywhere.” . “Once I got out of the train I could see the wreckage where it was like in giant C shape and I was in the back of the train. And the front of the train looked all mangled up, just piles of metal. And in the middle of the car you could see the car flipped on its side. And I saw people climbing up from the windows, you know, rescuing themselves.” . “And within I’d say about half an hour the first-responders came and they start triaging people, tagging people with the severity of the injury. And they shipped different people to different hospital.” // Reuters 3031 (SOUNDBITE)(English) JOAN HELFMAN, PASSENGER, SAYING: “I was in the front seat and this huge red suitcase came flying at me. our train was actually on our side, so it pushed me onto the side of the train.//I saw so many headd injuries and bloody faces and people were really injured They were thrown out of their seats.”

Mr. Hart said the safety board was examining other measures that could prevent deaths in train crashes, including installing seatbelts, recording audio in cockpits and examining the crashworthiness of trains. Many Amtrak trains were built in the 1970s.

Sarah Feinberg, the acting administrator of the Federal Railroad Administration, said her agency was also preparing a series of proposals that would address train speed, distractions in the cab and further training for engineers. She did not give a timetable for possible recommendations.

Joseph H. Boardman, Amtrak’s chief executive, told lawmakers that the railroad would have positive train control fully installed by Dec. 31. He said the railroad had made a number of changes since the Philadelphia accident to ensure the safety of passengers, including installing inward-facing cameras in train cabs.

Dennis R. Pierce, the national president of the Brotherhood of Locomotive Engineers and Trainmen, told lawmakers that the union had concerns about the cameras because railroads could use them to punish employees. “We just think there needs to be some controls in place on the use of cameras, and currently there are not,” Mr. Pierce said.

Despite the crash, Mr. Boardman said that the Northeast Corridor was the safest train route in the country.

“In no other place is a comparable volume of traffic moved with such a solid record,” he said. “In addition to a thorough training, oversight and coaching system for our crews, we have a layered signal system that provides trains with multiple levels of protection.”

Democrats criticized Republicans for moving to cut Amtrak’s budget the day after the crash. House Republicans approved $1.14 billion in funding for Amtrak next year, about $262 million less than the current level and well below the $2.45 billion requested by the Obama administration.

But Republicans rejected the suggestion that Amtrak’s funding had contributed to the derailment. Representative Scott Perry, Republican of Pennsylvania, pointed to the railroad’s losses on its food service and the bonuses given to employees. “Why can’t they spend 10 percent of what they lost on food service on P.T.C.?” he asked, referring to positive train control.
