The Fitchburg Railroad was Boston’s northern door to the Hudson. Massachusetts chartered it on March 3, 1842. Trains reached Fitchburg on March 5, 1845. Alvah Crocker, the Fitchburg paper-mill owner, wanted a westbound that did not have to climb the Boston & Albany’s Berkshire grades. The answer was the Hoosac Tunnel: first train through the bore on February 9, 1875. The Fitchburg gathered the Vermont & Massachusetts, the Cheshire, the Troy & Greenfield, and the Boston, Hoosac Tunnel & Western until the map ran Boston to Rotterdam Junction, New York. The Boston & Maine took a 99-year lease on July 1, 1900—the same morning the New York Central leased the Boston & Albany. The property became the Fitchburg Division. A 1919 reorganization folded the paper company into the B&M.
Mike Schafer, in Classic American Railroads, is the postwar freight note: more than a dozen scheduled freights a day on that route after World War II. Ronald Dale Karr, in The Rail Lines of Southern New England, is the branch and abandonment book. Bruce D. Heald, in A History of the Boston & Maine Railroad, is the B&M lease. The tunnel construction, the 1911 electrification, and the 1957 single-tracking stay on the Hoosac page. This page is the railroad that owned the west door.

A horse railroad from Boston to Brattleboro, Vermont, by way of Fitchburg was talked of in 1828. Nothing came of it. The piece that did get built was the Charlestown Branch Railroad, chartered April 4, 1835: a short line off the Boston & Lowell near Lechmere Point in Cambridge, across Miller’s River to Swett’s Wharf by the Charlestown Navy Yard. Horses from January 1840.
Crocker wanted steam to his mills. Nathan Hale, who had already been through a Boston–Worcester promotion, sat with him. The Fitchburg Railroad Company was incorporated March 3, 1842, to run from the Charlestown Branch at West Cambridge out to Fitchburg, about fifty miles across the hills of Middlesex and Worcester counties. Capital $800,000. Land beside the Charlestown Branch was bought in May 1843. Construction started May 20. Irish labor laid the first iron.
Waltham opened December 20, 1843, still under Charlestown Branch operation until May 1, 1844. Concord, June 17, 1844. Acton, October 1. Shirley, December 30. Fitchburg, March 5, 1845. The new track paralleling the Charlestown Branch opened in August 1844. The Fitchburg leased the branch on September 1, 1845, and bought it on January 31, 1846.
The first passenger terminal sat in Charlestown, southwest of City Square, west of the Warren Bridge. In 1848 the line was thrown across the Charles to Causeway Street, between Haverhill and Beverly, on the Boston side. Freight kept using the old Charlestown stub. North Union Station replaced the Causeway house in 1893. That is the ancestor of today’s North Station.
Henry David Thoreau, at Walden Pond, heard the trains and walked the Fitchburg to Concord. He disliked the noise and studied the cuts. The railroad was already a fact in the woods by 1854.
Fitchburg was not the west. The Vermont & Massachusetts Railroad, chartered 1844, took the idea on from Fitchburg: Baldwinville 1847 (the Fitchburg operated that first piece until 1849), Athol and Millers Falls 1848, Brattleboro 1850, and a branch from Grout’s Corner (Millers Falls) to Greenfield the same year. Turners Falls opened about 1871. The original V&M main north from Millers Falls went to the Rutland in 1870 and then to the Vermont Central, later the Central Vermont. In 1874 the Fitchburg leased what was left of the V&M—Fitchburg to Greenfield, and the Turners Falls branch—and had a railroad to the Connecticut River.
The Cheshire Railroad, New Hampshire 1844, Massachusetts Winchendon charter 1845, opened South Ashburnham to Winchendon and Troy, New Hampshire, in 1847, Keene 1848, Bellows Falls 1849. That was the Fitchburg’s door to the Vermont Central and, later, the Rutland. The Fitchburg merged the Cheshire in 1890. The Monadnock, Winchendon to Peterborough, came with it (Fitchburg control 1890; merged 1892). The Boston, Barre & Gardner, Worcester/Barber to Gardner (1871) and Winchendon (1874), was merged in 1885. Ashburnham, a V&M stub, the same year.
Closer to Boston the Fitchburg ran, leased, or bought the Lexington & West Cambridge (opened 1846; later a Boston & Lowell property), the Watertown Branch (1851), the Marlborough line from South Acton (1850–55), and the Peterborough & Shirley from Ayer toward Greenville, New Hampshire. Those branches paid mill traffic.

West of Greenfield the mountain sat in the way. The Troy & Greenfield Railroad was chartered in 1848 to run from the Vermont line at Williamstown through Hoosac Mountain to Greenfield. Rails from the state line to the west portal at North Adams opened in 1859. The Southern Vermont, across the southwest corner of Vermont, opened the same year. The Troy & Boston carried the idea on to Troy, New York. The tunnel itself is a Massachusetts story: state money after the Troy & Greenfield failed, Herman Haupt, nitroglycerin, twenty-four years, 193 dead. That encyclopedia is Hoosac. The railroad fact on this page is the date the iron was open: February 9, 1875. Regular Boston–Troy passenger trains, 1876. At 4.75 miles it was the longest railroad tunnel in the country.
The Fitchburg had already been using the finished east end under an 1866 state lease with the Vermont & Massachusetts. Crocker sat on both sides of that paper. When the bore opened, Boston finally had a northern freight line that did not have to take the Boston & Albany over Washington Summit.
In 1887 the Fitchburg consolidated the Troy & Greenfield and the Troy & Boston, took stock control of the Boston, Hoosac Tunnel & Western, and leased the Troy, Saratoga & Northern. The BHT&W had opened Massachusetts line to Mechanicville in 1879 and reached Rotterdam Junction in 1884, a New York Central connection west of Schenectady. Mechanicville sat on the Delaware & Hudson. That was the interchange that paid. The Fitchburg bought the BHT&W outright in 1892 and the Southern Vermont in 1891. A planned BHT&W extension toward Buffalo became, on other people’s paper, the West Shore.
By 1900 the ICC would count 394 miles: three mains, ten branches, double track on the busy pieces, yards and a Boston waterfront. Preferred stock, common stock, and a funded debt the B&M would have to service. The Cheshire gave Bellows Falls. The V&M gave Greenfield. The tunnel gave Troy, Mechanicville, and Rotterdam Junction. That is the railroad the Boston & Maine bought.

The Boston & Maine leased the Fitchburg for 99 years from July 1, 1900. The instrument is dated June 30; operations began the next morning. Annual rental was 5 percent on the preferred held by the public, 1 percent on the common, interest on the funded debt, and organization expenses. The B&M also assumed the Fitchburg’s own leases of the Vermont & Massachusetts and the Troy & Bennington. That same July 1 the New York Central took the Boston & Albany on a 99-year lease. New York chose the southern Massachusetts main. The B&M took the tunnel.
The Fitchburg kept a paper company. On December 1, 1919, the B&M reorganization merged the principal leased roads, Fitchburg included, into a new Boston & Maine. The name on the locomotives was already B&M. The Fitchburg Division was the operating title that stuck: North Station to East Deerfield, the tunnel, Mechanicville, Rotterdam Junction. J. P. Morgan and the New Haven had taken B&M control around 1910; the Fitchburg obligation was part of the debt that put the B&M into receivership in August 1916. That story is the Boston & Maine.
Steam in the tunnel was a choking assignment. The B&M electrified Hoosac in 1911. Diesels replaced the motors in the 1940s. Single track returned in 1957 for clearance. Last regular passenger train through the bore, November 28, 1958. Those dates, and the FT test of September 5, 1940, stay on the tunnel page. East Deerfield became the hump for westbound freight. Mechanicville remained the New York end, at the Hudson and the D&H.
The Boston–Troy name train under the B&M was the Minute Man, later a job for the Flying Yankee trainset after it left the Bangor run. Passenger cuts came in a rush at the end of the 1950s: Troy to Williamstown, January 19, 1958; Cheshire Branch, May 18, 1958; west of Greenfield, December 30, 1958; west of Fitchburg, April 23, 1960. What was left was a Boston commuter railroad on the old charter line.
The MBTA signed a north-side subsidy with the B&M in 1964. On December 27, 1976, it bought the Boston–Fitchburg right-of-way, with the rest of the north-side commuter plant. Service to Gardner came back in 1980 and died again January 1, 1987, in a Guilford–Amtrak fight; the T only owned the iron to Fitchburg. Wachusett opened in 2016. Guilford took the B&M on June 30, 1983. Pan Am was the 2006 name. CSX closed on Pan Am on June 1, 2022. Freight west of Ayer on the old Fitchburg is the Patriot Corridor: Norfolk Southern and the Berkshire & Eastern, a Genesee & Wyoming operator, as Pan Am Southern. The charter line into North Station is an MBTA commuter railroad. The west door Crocker wanted is still a freight railroad. The paper company of 1842 is not.
