Deadly Washington DC Train Crash Caused by Careless Inspections
According to an article in the Oklahoman, the National Transportation Safety Board (NTSB) determined that a Washington D.C. Metro 2009 train crash that occurred nearly a year ago was caused by a defective electrical circuit. The NTSB found that the electrical circuit did not alert the oncoming train that another train remained stationary on the track.
The train crash killed 8 passengers as well as the train’s conductor. When the stopped train became visible to the moving train, the conductor attempted to brake, but the train conductor only had 3 seconds to react, which was not enough time to avoid the collision. The entire train accident could have been avoided if the Metro’s signal system had been functioning properly that day.
