During the Martin Luther King, Jr. Holiday weekend, Metro will rebuild the trackbed, which means workers will install 1,400 feet of new rail, 310 new ties, 200 new tons of ballast, 300 new track fasteners, 600 new anchor bolts, repair 200 feet of grout pads on the aerial structure, and make track circuit upgrades between the Grosvenor-Strathmore and Medical Center Metrorail stations. In addition, workers will repair 60 to 80 water leaks in the tunnels and stations and install 300 new tunnel lights.
According to metro, "From Friday, Jan. 15, to Monday, Jan. 18, the last Red Line train departing the Shady Grove Metrorail station for the White Flint Metrorail station will leave 30 minutes earlier than usual." Of course, that isn't really true, the last trains won't leave earlier, they just won't run. This is metro's spin way of saying they are closing early.
