The New Brunswick Southern Railway Company Limited is a Canadian short line railway owned by the New Brunswick Railway Company Limited, a holding company that is part of "Irving Transportation Services", a division within the industrial conglomerate J.D. Irving Limited. Together with its sister company Eastern Maine Railway , NBSR and EMRY form a continuous main line connecting Saint John, New Brunswick, with Brownville Junction, Maine. NBSR also operates an additional of branch lines in New Brunswick. Today most locomotives hauling trains that operate over NBSR and EMRY are owned and carry the reporting marks of NBSR. Some maintenance of way equipment that operates exclusively in the state of Maine is owned directly by EMRY. A sister company Maine Northern Railway operates a separate railway system connecting Millinocket, Maine, with Van Buren, Maine. History NBSR was established as a corporate entity in November 1994 by J.D. Irving Ltd. to purchase 131.7 miles of physical railway assets of the Canadian Pacific Railway within the province of New Brunswick; these being the 84.4 mile McAdam Subdivision, the 5.6 mile section of the Mattawamkeag Subdivision within Canada, as well as the West Saint John Spur, Milltown Spur, and the St. Stephen Subdivision. The actual land forming the right of way that CPR's tracks were located on was actually already owned by J.D. Irving Ltd. CPR sold all of its land holdings in New Brunswick (but not the tracks and buildings) in 1941 when it reached an agreement that saw industrialist K.C. Irving purchase the New Brunswick Railway Company Limited. This arrangement allowed J.D. Irving Ltd. to use New Brunswick Railway Co. Ltd. as a holding company to own both the NBSR as well as its U.S. sister EMRY. Ownership of the tracks in New Brunswick extends to the Canada–United States border at the midpoints of two crossings of the St. Croix River; these being the Saint Croix-Vanceboro Railway Bridge at St. Croix shared with the EMRY, as well as an unnamed railway bridge at St. Stephen shared with Pan Am Railways . Both NBSR and EMRY began operations on January 6, 1995, approximately one week after Canadian Pacific Railway abandoned operations of its Canadian Atlantic Railway (CAR) subsidiary on December 31, 1994. In spring 1995 Irving Transportation Services consolidated its railway operations as Eastern Maine Railway Company Limited came under NBSR operational control and NBSR trains and crews operate over both short lines
