When will passenger service begin on with the Silver Line? It’s not clear.

A costly delay in the completion of the first phase, which will run between East Falls Church and Wiehle Avenue in Reston, has left that date in question. But enough about that still uncompleted phase: What about phase 2?

As the Washington Post reports, officials have set up a hotline for questions and concerns about the project.

The toll-free hotline will be staffed 24 hours a day, seven days a week. The number is: 1-844-385-RAIL.

Questions or concerns will be relayed to staff members with Capital Rail Constructors, the contractor responsible for building the second phase of the rail line. Preliminary work on the second phase, which will have six stops, including one at Dulles International Airport, has begun. It is expected to open in 2018.

But hey, we already have signs!
