WASHINGTON (AP) – Federal investigators are going to test the automated system that is meant prevent train crashes like the one in Washington, D.C., that killed nine people.
Debbie Hersman of the National Transportation Safety Board says investigators are going have their first opportunity Wednesday to test the computerized signal system. The train was under automatic control at the time of the crash, and investigators say there was evidence the operator tried to stop it.
Hersman tells ABC's "Good Morning America" that investigators are trying to understand how the automatic system works and if there were any problems. Investigators will also review maintenance records.
A train plowed into a stopped train Monday in the deadliest accident in the 33-year history of the Metro.
