Good news for Washington residents or anyone visiting. As detailed by the Washington Post here http://www.washingtonpost.com/wp-dyn/content/article/2008/09/22/AR2008092201144.html, Metro's needs are considerable and include "replacing one-third of its rail fleet, about 300 rail cars that are more than 30 years old and nearing the end of their life cycle; replacing about 100 buses every year; repairing leaky tunnels and crumbling station platforms; and repairing bus garages, one of which is more than 100 years old."
