The Bangor and Aroostook Railroad was a United States railroad company that brought rail service to Aroostook County in northern Maine. Brightly-painted BAR boxcars attracted national attention in the 1950s. First-generation diesel locomotives operated on BAR until they were museum pieces. The economic downturn of the 1980s, coupled with the departure of heavy industry from northern Maine, forced the railroad to seek a buyer and end operations in 2003. It was succeeded by the Montreal, Maine and Atlantic Railway. History The company was incorporated in 1891 to combine the lines of the former Bangor and Piscataquis Railroad and the Bangor and Katahdin Iron Works Railway. It was based in Bangor and lines extended from there to Oakfield and Houlton in 1894. The line was extended from Houlton to Fort Fairfield and Caribou in 1895. A parallel branch line was extended from Oakfield to Ashland in 1896. A branch was built from Caribou to Limestone in 1897, and the main line extended from Caribou to Van Buren in 1899. The Ashland Branch was extended to Fort Kent in 1902. A southern extension was completed in 1905 through Northern Maine Junction to Searsport on Penobscot Bay. The Medford Cutoff from Packard to South Lagrange was completed in 1907, and a branch was built from Millinocket to a new paper mill in East Millinocket. Rails were extended up the Maine side of the Saint John River from Van Buren through Madawaska and Fort Kent to St. Francis in 1910; and Mapleton was connected to Stockholm and Presque Isle on the main line, and to Squa Pan on the Ashland branch. An international bridge was constructed over the Saint John River between Van Buren and St. Leonard, NB in 1915 to connect with the Canadian Pacific Railway and National Transcontinental Railway (later merged into the Canadian National Railway). BAR began hauling potatoes in heated boxcars in 1895. Potatoes provided a stable income source through the great depression, and provided 50% of the railroad's revenue following World War II. BAR had the second-largest United States railroad-owned reefer fleet (after Santa Fe) during the 1950s. BAR made an arrangement with Pacific Fruit Express whereby PFE reefers shipped Maine potatoes during winter months and BAR reefers carried California produce during the summer and autumn. While potatoes started moving by truck following completion of the Interstate Highway System into northern Maine in the 1960s, what actually resulted in
