NTSB Worried About Safety Of Train Signal Warning

BOSTON (WBZ) ― A federal safety board is urging checks by all transit lines and railroads that use the same signal system that failed to detect a stopped train in a deadly crash in Washington, DC earlier this year.

Boston is one of the cities with a similar system.

The June 22 crash in Washington killed nine people and injured 70 others. One train was not able to stop in time before slamming into another parked train.

There was a malfunction in the automated system that uses sound waves to warn trains about other trains on the tracks.

Now the National Transportation Safety Board is concerned the same problem could occur in similar systems, such as Boston and other cities.

"Our findings so far indicate a pressing need to issue these recommendations to immediately address safety glitches we have found that could lead to another tragic accident on WMATA or another transit or rail system," NTSB Chairman Deborah A.P. Hersman said in a statement Tuesday.

MBTA officials say there have been no incidents regarding signals over the years, but they are following the warning and getting the inpections done anyway. Spokesperson Joe Pesaturo tells WBZ the Red Line was upgraded in 2000 and the Orange Line has been updated over the past five years, which equals about 32 miles of track.

The NTSB had said previously that equipment that is supposed to detect stopped trains failed periodically in the days leading up to the crash.

The DC Metro also said the system failed to detect trains during tests after the crash.

The NTSB has requested responses from each of the rail agencies within 30 days on the urgent recommendations, with steps they have taken or plan to take.
