WASHINGTON (WUSA9) - Metro has started its longest stretch of single-tracking ever.
For 42 days, the Orange Line will be limited to one track between Vienna and West Falls Church as part of Metro’s massive safety overhaul.
Crews are replacing 4,000 rail ties across six miles of track.
Riders in the work zone must get on a special shuttle train that runs only every 24 minutes.
This safety surge ends Oct. 26.
