The Downeaster is a 141-mile passenger rail service that runs from Boston to Portland, Maine and on to Brunswick, carrying over 540,000 people per year. The service began in 2001 after years of track improvements and the establishment of the Northern New England Passenger Rail Authority in 1995. Expansion to Brunswick was completed in 2012, though service was delayed in 2011 after a fatal collision between a Downeaster train and a tractor-trailer.
