Eleven New Jersey Transit engineers and conductors are temporarily taken off duty as part of a new program to assess fatigue-related conditions.

The agency started the program after the fatal train crash in Hoboken this past September.

The train's engineer was diagnosed with sleep apnea after the crash.

Investigators say he was going twice the speed limit when it entered the station.

The collision left one person dead and more than 100 people were injured.

New Jersey Transit officials say any engineer or conductor who shows signs of fatigue will be removed until they can prove they've controlled or corrected the condition.

Under previous rules, engineers with sleep apnea were allowed to keep working as long as they were being treated.
