MWAA Officials Investigating Silver Line Test Derailment
Slow-moving train hit derailer in first test-phase mishap.
The Metropolitan Washington Airports Authority (MWAA) is trying to determine why a Silver Line test train derailed Tuesday near Wolf Trap.
The train’s front axle left the track after hitting a derailer, a mechanism designed to derail the train if it goes beyond where it is supposed to travel, Pat Nowakowski, executive director of the Dulles Rail Project, told The Washington Post.
No injuries were reported, and the train was taken out of service, he added.
