Several Orange Line stations shut this weekend This is a relatively light weekend for Metro's rebuilding program and resulting disruptions, except on the Orange Line, where two stations will be closed. Here are the details for all three lines affected by the program this weekend. Vienna and Dunn Loring, the two westernmost stations on the line, will be closed from 12:01 a.m. Saturday through Metrorail's midnight closing Sunday while crews work on the tracks between Vienna and West Falls Church. Trains will operate on their regular weekend schedules between West Falls Church and New Carrollton. Free shuttle buses will take riders between Vienna and West Falls Church. Express buses will stop only at Vienna and West Falls Church. The trip should take about 24 minutes. A local route will make an intermediate stop at Dunn Loring. It should take about 15 minutes to travel between each station. Crews will work on the tracks between Grosvenor and Twinbrook, and on the lighting and fencing between Rhode Island Avenue and NoMa-Gallaudet. From 10 p.m. Friday through the midnight closing Sunday, trains are scheduled to leave the ends of the line at Shady Grove and Glenmont every 16 minutes. From 9 a.m. to 9 p.m. Saturday and Sunday, more trains will be in service between Grosvenor and NoMa-Gallaudet. In that zone, trains should reach platforms every eight to 10 minutes. The trains are scheduled to operate normally, except at the Franconia-Springfield terminal on Saturday, while crews work on the tracks between Van Dorn Street and Franconia-Springfield. Trains will arrive and depart from Franconia-Springfield every 20 to 25 minutes between 9 a.m. and 9 p.m. On Sunday, the trains will be on their normal schedules all along the line.
