Test Trains to Roll on Silver Line Phase 2
Early Wednesday Morning
The first trains to roll along the tracks of Phase 2 of the Silver Line are expected around 1 a.m. Wednesday in early tests of the new system, which will connect the Metrorail system to Dulles International Airport and points in Loudoun County.
Two two-car trains that will be used to polish the third rail, which carries electric current that powers Metro trains, from the Innovation Center Station through Washington Dulles International Airport to the end of the aerial guideway west of the airport. Polishing is necessary to remove rust that can accumulate on rails that are not frequently used. Because the third rail will not be electrified during this portion of the test, the trains will be pushed by a small diesel locomotive.

The two trains to be used in the test will move from the Wiehle-Reston Metro station to the Innovation Station at a speed of about 15 mph. Capital Rail Constructors, the project design-build contractor, plans to complete the work by 4 a.m. If both trains cannot be moved by then, the second train will be moved the following night.
After the trains are in place at Innovation, the third rail will be electrified between Innovation Center Station and Dulles International Airport, where trains will be used to remove accumulated rust from the third rail in that area.
Project officials warn that the entire track is a "live track," which could be carrying electric current.
When this work is complete, two additional trains equipped for safe-braking tests will be brought in, which would begin the "dynamic testing" process that is required before the rail line begins commercial operation, according to Charles Stark, senior vice president of the Metropolitan Washington Airports Authority, which manages construction of the Silver Line project.
This work, which project officials consider a significant milestone, will continue for several months.
PLEASE DRIVE CAREFULLY! Drivers are asked to use caution. Large, slow-moving vehicles may be exiting and entering the highways at various times.
