Seems like it was just yesterday, but it has been five years since the Red Line disaster killed a Metro operator and eight riders near the Fort Totten station. Efforts to erect a permanent memorial finally culminated in a groundbreaking Sunday on a new, $1.8 million Legacy Memorial Park, located at the foot of the New Hampshire Avenue bridge where the collision took place. The Washington Post’s Julie Zauzmer reports: “Once completed, the park will have nine sculptures, one for each victim of the crash, as well as benches, lighting and a canopy of entwined sycamore trees.” Columnist Bob McCartney, meanwhile, examines Metro’s record since the devastating crash — including the surprising claim from the federal safety official who investigated the crash that the system has gone “from worst to first.”
