On April 1, 1887, the B&M leased the Boston and Lowell Railroad, adding not only trackage in the Boston area, but also the Central Massachusetts Railroad west to Northampton, the Boston, Concord and Montreal Railroad into northern New Hampshire, the St. Johnsbury and Lake Champlain Railroad to northwestern Vermont, and the Connecticut and Passumpsic Rivers Railroad from White River Junction into Quebec. However, the BC&M was separated in 1889 and merged with the Concord Railroad to form the Concord and Montreal Railroad, which the B&M leased on April 1, 1895, gaining the Concord Railroad's direct line between Nashua and Concord. Additionally, the St. Johnsbury and Lake Champlain Railroad, owned by the B&M through stock, was leased to the Maine Central Railroad by 1912. The Central Massachusetts Railroad stayed a part of the B&M, as did the Connecticut and Passumpsic Rivers Railroad (as the Passumpsic Division).
