Boston and Maine Railroad
transport company

The Boston and Maine Railroad (reporting mark BM; commonly known as Boston & Maine, abbreviated B&M) was a U.S. Class I railroad in northern New England. It was chartered in 1835, and became part of what was the Pan Am Railways network in 1983, most of which was purchased by CSX in 2022.
At the end of 1970, B&M operated 1,515 route-miles (2,438 km) on 2,481 miles (3,993 km) of track, not including Springfield Terminal. That year, it reported 2,774 million ton-miles (4,464 million kilometres) of revenue freight and 92 million passenger-miles (148 million kilometres).
History
The Andover and Wilmington Railroad was incorporated March 15, 1833, to build a branch from the Boston and Lowell Railroad at Wilmington, Massachusetts, north to Andover, Massachusetts. The line opened to Andover on August 8, 1836. The name was changed to the Andover and Haverhill Railroad on April 18, 1837, reflecting plans to build further to Haverhill, Massachusetts (opened later that year), and yet further to Portland, Maine, with renaming to the Boston and Portland Railroad on April 3, 1839, opening to the New Hampshire state line in 1840.
The Boston and Maine Railroad was chartered in New Hampshire on June 27, 1835, and the Maine, New Hampshire and Massachusetts Railroad was incorporated March 12, 1839, in Maine, both companies continuing the proposed line to South Berwick, Maine. The railroad opened in 1840 to Exeter, New Hampshire, and on January 1, 1842, the two companies merged with the Boston and Portland to form a new Boston and Maine Railroad.
On February 23, 1843, the B&M opened to Agamenticus, on the line of the Portland, Saco and Portsmouth Railroad in South Berwick.
This brief starts where responsible research should: with the source description of “Boston and Maine Railroad” as transport company. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as transport company. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Aug 1, 2026. The linked authority identifier is Q638715. VIAF identifies the subject as 261739750. The Library of Congress control number is n86134579. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1835, 1983, 2022 and 1970.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
