Operator moved the train without permission and overrode the zero speed command

Metro is planning a software change for the 7000 series, but not 2000/3000 series

Reported speed was 11mph
At 11 mph, he couldn't see the other train in time to stop?
It probably happened at the curve just west of Farragut West, it's a blind spot

I have walked that tunnel. The curve in question is on an up hill grade turning to the left. The site line from the right hand operators position in that tunnel is around 250' to 350', well with the stopping distance of 15 MPH.

A train normally enters a station at 35 to 40 MPH and comfortably stops within 600'.

The operator likely creeped up on the train ahead and made his brake application to stop short of the train to late.
