Amtrak says it will begin installing a new layer of safety: Cameras that will focus on the train's engineer and control panels.

FOX News Radio's Gurnal Scott reports:

The new inward-facing cameras will be installed in the locomotive fleet -- including long-distance trains and those that travel the busy Northeast Corridor from DC to Boston.

Amtrak President and CEO Joe Boardman says this will add another investigative tool. The NTSB says such a vantage point could have helped in the probe of the deadly Philadelphia derailment -- since the engineer onboard that train said a head injury wiped out his memory of what happened.

About 38 trains will have the cameras by the end of the year. The rest by next Spring.
