What KOOLjock1 posted is correct. It was in the statement the NTSB released last night. The CSX train was backed into the siding and tied down. It had been switching the automotive loading/unloading facility across the track. The train did not run out of time.
The main question according to the NTSB, is who left the switch lined and locked for the siding. I have my own opinion, but will wait for the NTSB. to come to their conclusions.
