Conductor in Metro North Crash May Have Suffered From Severe Sleep Apnea

The derailment occurred on Dec.1, 2013 when the conductor reportedly nodded off at a sharp turn near the Spuyten Duyvil train station, leaving four dead and 70 injured. He apparently had a recent change in his schedule to an early-morning shift.   After the accident, the conductor was evaluated by a Board Certified physician in Sleep Medicine, who also performed a non-invasive polysomnography that revealed severe obstructive sleep apnea. He had a BMI of 34 kg/m2 and an initial Epworth Sleepiness Score of 12. No pre-accident screening or evaluation was performed for sleep apnea. Click for the New York Times article.
