The National Transportation Safety Board says the investigation into the Hoboken train crash has been hampered by safety issues.

NTSB Vice Chairwoman T. Bella Dinh-Zarr said Thursday that the canopy of Hoboken's Lackawanna Train Station is resting on top of the car that sped off the tracks and the NTSB is waiting until it's safe to go into that area.

Dinh-Zarr said water has been leaking into the station all day and there may also be asbestos contamination because of the age of the building. The station is over 100 years old.

The chairwoman said investigators have access to the train's locomotive and expected to pull the train's data recorder Thursday night.

She says the train's engineer was controlling the locomotive from a control cab in the train's front passenger car.

Dinh-Zarr said NTSB investigators will most likely be on the scene for seven to 10 days.

Pascack Valley Line train No. 1614, en route from Spring Valley, New York, crashed into the station around 8:45 a.m. Witnesses say the train was traveling at a high rate of speed prior to the crash.

Fabiola Bittar de Kroon, 34, of Hoboken was struck and killed by debris while standing on the train platform. Over 100 other people were injured.
