WASHINGTON, D.C. METRO IMPROVEMENTS: Facing budget cuts and a maintenance backlog, Washington, D.C. Metro officials claim that reversing the decline of the transit system will take years. Among the first steps toward improving the system is placing a greater focus on preventive escalator maintenance. Correspondingly, Metro plans to complete 60% of its maintenance on time, compared to the current 40%. Escalator crews will focus on units that are 30 days past their inspection date, and learn which escalator parts are still manufactured and which will require custom fabrication. In addition, this year will see 16 escalators repaired or replaced, mostly on the Red Line.
