Scheduled track work could make for a longer than usual wait on the Metro platform this weekend.
Starting at 10 p.m. Friday, Orange Line trains will run just once every 24 minutes all weekend. Blue Line and Yellow Line trains will run once every 20 minutes. On the Red Line, trains will run from end to end just once every 20 minutes, but Saturday from 9 a.m. to 9 p.m. and Sunday from 9 a.m. to 10 p.m., extra trains running between Grosvenor and NoMa-Gallaudet will make the wait more like 10 minutes through that stretch.
Service on most of the Green Line will be normal all weekend, except for Saturday only at the Greenbelt station where trains will arrive and depart just once every 24 minutes.
Metro has updated its major track work calendar through the end of 2014 and is encouraging community groups and event planners to check it out when planning events during the second half of the year. It's available on Metro's website.
