#TBT: @wgbh cameras capture a ground-level view of the elevated Orange Line train humming along Washington Street in Boston's South End in 1977. Earlier this week, the MBTA announced that it would temporarily be shutting down the Orange Line for a 30-day period starting Aug. 19. It will be the longest service disruption in the commuter rail's history. Gov. Charlie Baker said the unprecedented closure will permit work to be completed that would otherwise take five years if done only during overnights and weekends.
