Other service truncations also occur in the system during rush hour service only. On the Red Line, every other train bound for Shady Grove terminated at until December 2018, in addition to the alternating terminations at Silver Spring mentioned above. For the Yellow Line, all non Rush+ trains bound for and all normal trains bound for terminate at . These are primarily instituted due to a limited supply of rail cars and the locations of pocket tracks throughout the system. However, as of July 2019, both Red Line service truncations have ended, and as of April 2019, the Yellow Line served Greenbelt at all times. When the Yellow Line reopened on May 7, 2023, following major maintenance work, the Mount Vernon Square turnback was reinstated at all times, which has not happened since 2006.
