Yes, this does boggle the brain.
Reports indicate that "metal tools" were not utilized to prevent the train from rolling.
I can only presume that such tools are wheel chocks or sprags.
NO mention of hand brakes is made in the report.
I will await to see it the train was air brake or vacuum system, such not being mentioned.
And, were there actually a total of 7 employees on the train ?
Another interesting incident report to peruse once published.
