A commuter train accident is the latest problem for Metro-North. Here is a look at some of the others:
• On March 10, 2014, a worker was killed by a train in Manhattan while trying to re-energize tracks that had been out of service for maintenance.
• On Dec. 1, 2013, a sleep-deprived engineer nodded off just before taking a 30 mph curve at 82 mph in the Bronx, causing a derailment that killed four people and injured more than 70. He had fallen asleep because of a severe, undiagnosed case of sleep apnea.

• On July 18, 2013, 10 train cars hauling garbage derailed in the Bronx.
• On May 28, 2013, a track foreman was struck and killed by a passenger train in West Haven, Conn. He had requested a track section be taken out of service for maintenance, and the section was placed back in service too soon by a student traffic controller.
