Amtrak plans to install video cameras to monitor the engineers of locomotives on its heavily traveled routes in the northeastern United States.

"Inward-facing video cameras will help improve safety and serve as a valuable investigative tool," Amtrak Chief Executive Joe Boardman said in a statement.

The cameras will be installed in 70 locomotives that power trains on the Washington-to-Boston northeast corridor, as well as service between New York, Philadelphia and Harrisburg, Pennsylvania, reported Reuters.

Amtrak is still looking into ways to install cameras in the high-speed locomotives that power its Acela express line through the region and on diesel-powered locomotives, Reuters said. 

The Federal Railroad Administration last week ordered Amtrak to take immediate steps to improve the safety of its busiest route, including identifying dangerous curves along the Northeast Corridor where slower speeds could reduce the risk of mishap.
