WOODBURY - Amtrak announced yesterday that cameras are going to be installed inside its train cabs.

The move follows the deadly derailment in Philadelphia earlier this month.

Safety experts say the devices could give more insight into the moments before a crash. Metro-North has also agreed to install the cameras.

Sen. Charles Schumer wants the LIRR to follow suit and install the cameras.    

Amtrak operates 300 trains nationwide.

So far, there is no timetable on when the cameras will be installed.
