NTSB Says Amtrak Engineer Applied Brakes, Sounded Horn Before Collision With CSX Train

February 5, 2018

The National Transportation Safety Board said on Monday afternoon that the engineer of Amtrak’s southbound Silver Star had applied the train brakes seconds before it struck a parked CSX freight train in a siding in Cayce, South Carolina.

The engineer also sounded his locomotive’s horn for three seconds.

NTSB investigators have said that a misaligned switch routed Amtrak train No. 91 into the path of the CSX train, which did not have a crew aboard at the time of the collision early Sunday  morning.

Chairman Robert Sumwalt said investigators found the data event recorders of Amtrak P42DC No. 47 undamaged in the wreckage.

The Amtrak engineer and an Amtrak conductor in the cab of the locomotive were killed in the crash, which also left 116 people aboard the train injured.

Sumwalt said the data showed that seven seconds before impact, the locomotive horn sounded for three seconds. The train was traveling at 56 miles per hour at that point, which was slightly slower than the 59 mph top speed allowed at that location.

Five seconds before impact, the brake pipe pressure began decreasing, indicating that the train brakes were being applied. The engineer had also moved the throttle from full to idle, which dropped the train’s speed to 54 miles an hour.

Three seconds before the collision, the emergency brakes were applied.

Sumwalt said the force of the collision moved the lead CSX locomotive 15 feet back from its location.

The switch that is the focus of the investigation was described as a hand-thrown switch that was found to have been locked into position to route a train from a mainline track into a siding.

The CSX train was sitting stationary 659 feet from the switch. Sumwalt indicated that aligning the switch for a straight move on the main would have been the responsibility of a CSX employee.

“We want to understand why that was the case,” Sumwalt said of why the switch was aligned as it was.

He said investigators found no mechanical problems with the switch.

Thus far, NTSB personnel have interviewed the CSX engineer, conductor, dispatcher, and a trainmaster. They plan to interview the surviving Amtrak crew members on Tuesday.

Earlier reports indicated that the signal system in the area of the crash was in the process of being upgraded and that trains were operating under track warrants issued by the dispatcher.

Sumwalt declined to reveal what the CSX employees said during the interviews.

He also declined to assess any blame. “I’m confident that our investigators will be able to piece this back together,” Sumwalt said.

NTSB Names Acting Chairman

March 20, 2017

Bella Dinh-Zarr has been named as acting chairman of the National Transportation Safety Board after the term of incumbent Chairman Christopher Hart expired last week.

Hart remains a member of the five-member board and had served as chairman since March 2015.

He had served as acting chairman for nearly a year before being nominated by the Obama administration to be the permanent chairman.

Dinh-Zarr has served as vice chairman since March 2015. Before joining the NTSB, she served as director of the U.S. Office of the FIA Foundation, an international philanthropy organization that promotes safe and sustainable transportation.
NTSB members are nominated by the president and confirmed by the Senate for five-year terms. By law, a board member is designated by the president to be the chairman while another is designated to be the vice chairman for two-year terms.
