Starting in 2016, Metro began to temporarily scale back service hours to allow for more maintenance. On June 3, 2016 they ended late night weekend service with Metrorail closing at midnight. Hours were adjusted again the following year starting on June 25, 2017, with weeknight service ending a half hour earlier at 11:30pm; Sunday service trimmed to start an hour later – at 8 a.m. – and end an hour early at 11 p.m.; and late night service partially restored to 1 a.m. The service schedule was approved until June 2019.
