We've heard plenty of talk about the dangers of sending text messages while driving. There have been plenty of warnings about the menace of texting while walking. It only makes sense, then, that it's probably best to refrain from doing it while operating heavy machinery, like, say, a commuter train.

According to a new report, however, SMS may be at center of a recent railway collision that resulted in the death of 25 people in Los Angeles.

The train collided head on with a Union Pacific train in Chatsworth, California, after it failed to stop of a signal. According to a local CBS affiliate, two 14-year-olds claim to have received text messages from the engineer shortly before the crash. Searches of the wreckage did not turn up the cell phone of the engineer who was killed in the crash.

The National Transportation Safety Board, however, has announced that they will continue investigating the issue. "We are going to be obtaining records from their cell phones and from the cell phones of the deceased engineer and will use our subpoena authority or whatever other legal authority we need and to begin to determine exactly what happened and what if any role that might have played in this accident," NTSB board member, Kitty Higgins told the AP.
