(AP)-- A commuter train slammed into an SUV on the tracks at railroad crossing about 20 miles north of New York City on Tuesday evening, killing at least seven people.
The crash is the latest problem for Metro-North, the nation's second-busiest railroad. 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. The National Transportation Safety Board said the engineer had fallen asleep at the controls because he had a severe, undiagnosed case of sleep apnea.
— On Sept. 25, 2013, a feeder cable in suburban Mount Vernon, New York, failed, knocking out power for 12 days to Metro-North's New Haven line, which carries 132,000 commuters daily.
— On July 18, 2013, 10 freight train cars hauling garbage derailed in the Bronx, and service was suspended.
— On May 28, 2013, a track foreman was struck and killed by a passenger train in West Haven, Connecticut. The NTSB says 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 who didn't have the required approval.
— On May 17, 2013, an eastbound train derailed in Bridgeport, Connecticut, and was struck by a westbound train. The accident injured 73 passengers, two engineers and a conductor.
