UPDATE, 11:50 a.m. Firefighters leaving, but power will stay off until MBTA workers fix whatever was causing flames when the power was on.
The Orange Line, which was delayed earlier this morning because of smoke from the tracks at Malden Center, is delayed again as firefighters try to figure out why something is burning on the tracks, this time near Forest Hills. Power has been shut in both directions. Buses are being called in to replace trains between Forest Hills and Stony Brook.
