TARRYTOWN, N.Y. (Reuters) - Data to be released on Thursday from a train that slammed into an SUV at a suburban New York crossing this week could shed more light on what caused the crash that killed six people and worried commuters on one of the busiest U.S. rail networks.

National Transportation Safety Board (NTSB) investigators said the main question was why the vehicle had stopped on Tuesday evening at the crossing in Valhalla, an affluent town north of New York City.
