LOS ANGELES (AP) - Federal investigators say audio recordings from a commuter train are missing required verbal safety checks between the engineer and the conductor in the seconds before it collided with a freight engine.
An official with the National Transportation Safety Board says the missing calls and responses are for the last two lights the train passed -- a solid yellow light and then a red signal. Red indicates the approach of another engine.
The NTSB also wants the cell phone records of two teenagers and the engineer as they probe whether text messages played a role in Friday's crash, which killed 25 people, including the engineer.
The teens tell KCBS-TV they received a text message from the engineer just moments before the crash.
The engineer's cell phone hasn't been found at the crash site.
