Federal investigators have found that the engineers of two commuter trains that crashed into stations were both suffering from severe sleep apnea.

The National Transportation Safety Board said Thursday the similar circumstances of the crashes warranted combining findings and recommendations into a single special report.

A woman standing on a platform was killed and about 110 passengers and crew were injured when a New Jersey Transit train going more than double the 10 mph speed limit slammed into Hoboken Terminal in September 2016.

More than 100 people were hurt when a Long Island Rail Road train crashed into a bumping post at the end of the tracks at Atlantic Terminal in Brooklyn in January 2017.

The NTSB has scheduled a hearing on the crashes for Feb. 6.

U.S. officials had pushed to require sleep apnea screening for truck drivers and train engineers after the crashes. But the Federal Railroad Administration and Federal Motor Carrier Safety Administration have since abandoned that plan.
