The operator of the Metro train that slammed into a stationary train in front of it apparently had activated the emergency brakes in a failed effort to stop before the accident, federal officials said yesterday as they searched for the cause of Monday's Red Line wreck that killed nine and injured 80.
Debbie Hersman of the National Transportation Safety Board said the emergency brake button, known as the "mushroom," was depressed, and the steel rails showed evidence that the brakes were engaged. Investigators also said the striking train was in automatic mode, which means onboard computers should have controlled its speed and stopped it before it got too close to the stationary train.
