Here’s the official from WMATA, complete with everything you need to know about commuting on Tuesday:

Red Line service will be severely impacted on Tuesday, June 23, as a result of a fatal collision on the Red Line on Monday, June 22, between the Fort Totten and Takoma Metrorail stations.

Red Line riders will have several options on Tuesday morning, however if they are able to avoid the Red Line, that may be the best option for Tuesday.

The Red Line will be operating in two sections on Tuesday. Trains will run back and forth between the Glenmont and Silver Spring Metrorail stations and between the Shady Grove and the Rhode Island Avenue-Brentwood Metrorail station. All trains will be six- and eight-car trains on the Red Line and they will be running about 8 to 10 minutes apart. Trains are expected to be very crowded.

The Brookland-CUA, Fort Totten and Takoma Metrorail stations will be closed to Red Line traffic.

Free Metrobus shuttles will be available to take customers around the incident between the Silver Spring, Fort Totten, Brookland-CUA, Rhode Island Avenue-Brentwood and Georgia Avenue-Petworth Metrorail stations. People can expect long waits for buses as a full Metrorail train often carries 100 people or more per car and a bus can only hold about 50 people at a time.

Metro officials recommend that customers who normally use the Red Line between the Glenmont and Silver Spring Metrorail stations should commute to Metrorail stations between the Shady Grove and Grosvenor-Strathmore Metrorail stations, or to use the following Metrobus lines to avoid the service disruption:

• Metrobus C8 line (Glenmont to White Flint)
• Metrobus Q2 line (Wheaton to Rockville)
• Metrobus C2, C4 line (Wheaton to Twinbrook)
• Metrobus J1 line (Silver Spring to Medical Center)
• Metrobus J2, J3, J4 line (Silver Spring to Bethesda)
• Metrobus L7, L8 line (Friendship Heights)

Metro officials also recommend that people utilize the Green Line from Greenbelt to the Fort Totten Metrorail station for service into downtown DC.
