The Washington County Railroad is a shortline railroad operating in Vermont and a sliver of New Hampshire, forming part of the Vermont Rail System. The WACR began operating in 1980 over the old Montpelier and Barre Railroad in Washington County, which the state acquired to ensure the continuance of rail service, and ceased operations in early 1999. Later that year, after interim service by other companies, operations were transferred to a new WACR subsidiary of the Vermont Rail System. In 2003, operations were greatly expanded through acquisition by the state and operation by the WACR of a former Boston and Maine Corporation and Canadian Pacific Railway line between Newport and White River Junction, which had most recently been operated by subsidiaries of the bankrupt Bangor and Aroostook Railroad.
