Test trains for the Silver Line are now running new tracks between Wiehle-Reston East and Ashburn.
But it’s still unclear how the Metropolitan Washington Airports Authority’s contractor plans to fix defective concrete rail ties that have put the tracks out of alignment.
According to the WTOP, MWAA wants the rail ties to be replaced, but that process might create additional delays.
Inspectors have been monitoring work on the concrete sealant and concrete areas that hold tracks in the rail yard.
So far, MWAA has rejected the contractors’ planned construction schedules. Negotiations are currently underway on the best way to speed things up.
