Lori Aratani, Washington Post transportation reporter, reports:
Officials say they are analyzing data collected from the first full test
run of Silver Line train service conducted over the weekend but still
have no firm date for when work on the $5.6 billion rail project will be
completed. . .
People familiar with the test run said it turned up a number
glitches, including ones linked to the system’s automatic train control
system, a key safety component that controls train movement and speed
and ensures proper spacing between trains — an issue that had delayed
completion of the project for several months. The individuals asked not
to be identified because they were not authorized to speak to the media.
In
at least one instance during Saturday evening’s testing, they said, a
train encountered a red signal, indicating that it should stop, yet
still received speed commands directing it to move forward. Marcia
McAllister, spokeswoman for the rail project, said officials would not
comment beyond their e-mail statement. . . .
