The document provides an overview of Metro's SafeTrack maintenance plan and its impacts on Fairfax County, Virginia. It discusses the accelerated track work schedule, expanded late night and weekend closures, and "safety surges" involving extended line closures. Ten of the 15 safety surges will affect Fairfax County stations on the Blue, Yellow, Orange and Silver lines. The county plans to promote alternative transit options, telework, and available parking capacity to mitigate impacts during the safety surges. Shuttle bus service will supplement reduced rail service, but capacity will be significantly lower than the rail system.
