Why was she supposed to stop???
She was being routed back to the yard and the train was in automatic. As far as the cell phone, my experience with WMATA operators is NEVER trust them to save my life. I have personnely observed them sleeping at the controls at least 500 times. Mr. Cherry being a 30 yr vetern I am sure he had observed as many sleeping at the controls as myself.
The track walkers should have been looking in both directions. My 29yrs of walking track for various railroads tells me a train can: 1. Run on any track. 2. At anytime. 3. And in any direction.
The track walkers let their guard down.
