Yes; today's Washington Post reports that the NTSB investigators have
found that the operator actuated both the regular manual brake and the
emergency brake when the automatic braking feature failed.
"The steel rails show that [operator Jeanice McMillan] activated the
emergency brakes 300 to 400 feet before the pileup, which occured on a
curved secton of track."
"The speed limit where the crash occurred is 59mph, the top speed on
the metro system. If the track circuit failed to detect the idling
train, computers inboard McMillan's train would have set her train's
speed at 59mph, making it difficult for her to hit the emergency
brakes in time to avoid a crash."
Racist asswipes like the OP are beneath contempt.
