Testing of Metro’s new Silver Line to start soon, but no firm opening date

Officials are expected to start testing trains on the Silver Line next weekend, but there is no set date for when the new line will debut to riders.

At a meeting Wednesday of the Metropolitan Washington Airports Authority, which is overseeing construction of the new line, officials said they had resolved a software issue linked to a critical safety system.

“We are now ready to take the next step,” said Jack Potter, president and CEO of MWAA.

In November, officials announced that completion of the first phase of the $5.6 billion rail project would be delayed after officials found problems with the software associated with the automatic train control system.

Now that the software issues have been resolved, Potter said officials will conduct a “simulated service” exercise in which Silver Line trains will run at the same time weekend Metro service is being run. The test will likely be run the weekend of Jan. 25.

“We thank everyone for their understanding and patience,” Potter said.

The November delay was the second time in six months that the project’s timeline had been moved back.
