The National Transportation Safety Board (NTSB) confirmed that train
control systems failed during investigative tests being carried out to
determine the cause of the Washington DC train crash on Monday that left
THE NTSB investigators have conducted tests at the accident site with a
similar train and found that when the train was stopped at the same
location as the train which was crashed into, the train control system
lost detection of the test train.
The investigators said metal to metal compression streak marks on both
rails of the track for ending near the point of impact were consistent
with heavy braking.
Investigators have collected recorder information from the struck train.
Data was recovered from eight of the nine recorders on the struck train
but could not be downloaded from one recorder. Two of the eight recorders
did not contain data related to the accident and some data collection
ended before the accident for undetermined reasons. The accident data is
now being examined by investigators in the NTSB's laboratory. The striking
train did not have any onboard accident data recorders.
