Repair crews completed work yesterday afternoon on a 15-foot section of Metro track that had been bent slightly by hot weather, and caused a subway train to derail.
The derailment involved a northbound train that jumped the track just before 2 p.m. Monday about 200 yards north of the Rogers Avenue station in Northwest Baltimore. More than two dozen passengers were slightly injured, but none was hospitalized.
Mass Transit Administration officials said the sustained heat of the past week caused the rail to bend.
Full service will be phased in over 24 hours, MTA spokeswoman Elana Mezile said yesterday. Officials advised riders, particularly during today's morning rush hours, to allow five to 10 minutes more travel time because fewer trains will be operating.
The derailment was the first Metro accident involving passengers since the system opened in 1983.
