 The Attleboro-Middleborough line was known as the Middleboro Secondary by the 1990s.The entire line was assigned to CSX in the 1999 breakup of Conrail, though CSX initially only applied the Middleboro Subdivision name west of Cotley Junction.From 1986 to 1996, the line was used by Amtrak's seasonal "Cape Codder" service.
