The National Transportation Safety Board is poised to release a cause of last year's multi-fatal Metro Red Line train crash. An NTSB spokesperson said the board will meet July 27 "to consider a final report" on the accident.
A Metro train slammed into the back of a stopped train on the Red Line during the height of rush hour on last June 22. Nine people including the train operator died, and 80 were injured in the deadliest accident in Metro history.
The NTSB held a three-day public hearing earlier this year, but was unable to determine a probable cause for the crash at that time.
In addition, the NTSB said progress has been made in investigations into three other Metro accidents, including one in January that killed two maintenance technicians when an high-rail truck backed into them. In that case, investigators continue to look at on-track protection rules, training and other issues.
