美国华盛顿城市改造计划

美国华盛顿城市改造计划：美国华盛顿市由于财政削减和大量的维修工作，其官方宣布城市交通运输系统的改造会持续几年时间。系统改造的第一步就是对电扶梯的安全维修工程。政府决定将在规定期限内完成60%的电扶梯维护工程，目前已经完成40%。维护人员会特别关注那些超过检查期限30天以上的电扶梯，找出需要进行维修的电梯。预计今年将维修和拆迁16部电扶梯。

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.
