CSX Signals Had Been Turned off For PTC Installation

Some news accounts of the head-on collision between an Amtrak train and a CSX freight train in South Carolina early Sunday morning mentioned that the signal system in place on the line had been turned off.

There was a reason for that. CSX crews were working to cut in a positive train control system on the route, the same system that National Transportation Safety Board Chairman Robert Sumwalt said might have prevented the crash.

During a news conference on Monday afternoon, Sumwalt said Amtrak’s southbound Silver Star was operating with track warrants in temporarily dark territory.  See a post below for an account of the final seconds before the crash.

Crews for Amtrak and CSX were in verbal contact with the dispatcher controlling that stretch of track where the work was being performed, which is the Columbia Subdivision of the Florence Division.

Sumwalt said NTSB investigators have thus far not found any problems with the track where the collision occurred in Cayce, South Carolina.

Earlier NTSB news briefings said that a switch had been left aligned to route Amtrak train No. 91 into the path of the CSX auto rack train, which was sitting on a siding without a crew onboard.

The collision, which destroyed Amtrak P42DC No. 47 and CSX AC44CW Nos. 130 resulted in an Amtrak engineer and conductor being killed.

Sumwalt said the NTSB inquiry will be broader than the mechanics of how the crash occurred.

“It is very important that we look at each of these incidents in isolation to determine if there are systemic issues,” Sumwalt, making reference to other incidents involving Amtrak in recent months. “Last Wednesday, it was a garbage truck that was on the track. We aren’t sure what happened here [and] why that switch was lined for the siding. We do look at safety culture issues and we did a report in October.”

That report, which reviewed an April 2016 incident in the Northeast Corridor in Pennsylvania that left two Amtrak maintenance of way workers dead, was critical of Amtrak’s lack of an effective safety culture.
