The drill will allow emergency personnel to practice the evacuation of a train during a simulated smoke and fire incident.
The exercise, which will take place inside the tunnel between Greensboro and Tysons Corner stations, will simulate real-world conditions to test coordination and communication between on-scene responders, Metro operations staff, Metro Transit Police and support personnel.
Metrobus operations staff will also use this drill as an opportunity to activate and test an agreement with Fairfax County to provide shuttle bus service via Fairfax Connector between Greensboro and Spring Hill stations.
The exercise will begin at 8:30 a.m. and is expected to conclude no later than 11 a.m. More than 100 emergency responders from various agencies, as well as volunteers, are expected to participate.
Free shuttle buses will replace Silver Line trains between Greensboro and Spring Hill stations Sunday until approximately 2 p.m.
Greensboro Station will be closed to the public from 7 a.m. until approximately 2 p.m. Metro will notify customers when the station reopens via email, text message and social media.
Members of the public in the area of Greensboro Station may notice a large number of emergency vehicles on site.
