Weekend Track Work on Orange, Red, Green Lines

TRACK WORK and rail car testing will lead to delays on the Red, Orange and Green lines this weekend. Here's what to expect:

» ORANGE LINE: This is where you'll find the heaviest of the weekend's work. From 10 p.m. Friday until midnight Sunday, trains will share the same track between Vienna and West Falls Church. Alternating trains will turn around at West Falls Church rather than proceeding to Vienna, so keep an eye on your train's final destination. Metro warns customers to add 30 minutes to their travel time.

» RED LINE: Track maintenance between Grosvenor and Medical Center could cause delays of up to 15 minutes, with trains in both directions sharing the same track. The work's scheduled to take place between 7 a.m. and 7 p.m. on Saturday and Sunday.

» GREEN LINE: New railcar testing between Greenbelt and College Park will force trains in both directions to share one track from 7 a.m. to 4 p.m. on Saturday. Add 10-15 minutes to your travel time.
