NEW YORK (AP) — New York Gov. Andrew Cuomo says conductors and engineers with two commuter railroads will need to undergo testing for sleep apnea (AP'-nee-uh) after a deadly 2013 derailment caused by a sleeping engineer.
Cuomo says Tuesday the testing will be required at the Long Island Rail Road and the Metro-North.
The Metropolitan Transportation Authority began testing some Metro-North engineers in 2015. Cuomo says that, as a result, some participants were required to undergo treatment for sleep apnea.
The pilot program did not require LIRR engineers to be tested.
In December 2013, a Metro-North engineer with undiagnosed sleep apnea fell asleep at the controls. Four people were killed and dozens injured when the train derailed in the Bronx.
