NEW YORK (AP) — Federal safety investigators will present their findings following a commuter rail crash that killed six people in the suburbs of New York City in 2015. The National Transportation Safety Board is scheduled to meet Tuesday in Washington, D.C.

The official says about 340 feet (100 meters) of electrified rail pierced the train after it struck an SUV at a crossing in Valhalla, New York.
