Formation

Following authorization in May 1846 by the Connecticut General Assembly to switch from a canal company to a railroad company, work began on building a railroad along the canal right of way.^[2] Starting in New Haven, the railroad reached Plainville, 27 miles (43 km) away, by the end of 1847. In 1850, it was joined by the Hartford, Providence & Fishkill Railroad's line between Hartford and Waterbury.^[3] The first trains ran in January 1848, though construction continued northwards to Granby.^[2]

Expansion and lease by the New York and New Haven Railroad

On January 11, 1848, the New York and New Haven Railroad leased the line between New Haven and Plainville for 20 years effective on July 1, 1849, for a price of $45,000 per year.^[2][3] Meanwhile, the New Haven and Northampton continued to build north. In 1849, the Canal Line made an attempt to reach Springfield, Massachusetts, and requested charters from the Massachusetts and Connecticut legislatures authorizing such an extension. This ran into intense opposition, both from the competing Hartford and New Haven Railroad, and from legislators in both states.^[4] Opponents argued that the New Haven and Northampton's charter authorized it to build a railroad "on or near" the right of way of the previous canal. This granted the company the freedom to diverge slightly from the canal's route where necessary by terrain or other obstacles, but also constrained them to follow the canal's general route, from New Haven northward towards Granby, and therefore not towards Springfield.^[4] The matter went to the Connecticut Superior Court, where a judge ruled that the railroad could not build towards Springfield, as doing so would violate its charter.^[5]

Between 1849 and 1850, two branch lines were constructed. The first was between Farmington and Collinsville, where it connected with Samuel W. Collins's Collins Company, a major manufacturer.^[6] The other was a short extension connecting Simsbury to Tariffville.^[2] Both opened in 1850, as did the extension of the main line to Granby. Almost immediately after they opened, the New York and New Haven leased these as well, effective April 25, 1850, for an additional $40,000 per year.^[3]

The New York and New Haven was motivated to lease the Canal Line as leverage in negotiations with the Hartford and New Haven. If the New Haven and Northampton were built to Northampton, it would be in direct competition with the H&NH's line between New Haven and Springfield, Massachusetts.^[2] These negotiations concluded with the New York and New Haven agreeing that the Canal Line would not build north of Granby, and only limited connecting service was to be made available with the HP&F in Plainville, since traffic could potentially travel between New Haven and Hartford via a transfer in that city. In return, the Hartford and New Haven contributed approximately $12,000 a year towards the New York and New Haven's payments for its lease of the Canal Line.^[3] This arrangement upset the communities along the Canal Line, such as Southington, which were left with poor service to and from Connecticut's capital city.^[7]

In spite of the "gentlemen's agreement" between the Hartford and New Haven and the New York and New Haven, the Canal Line's proponents were determined to still reach Northampton. To this end, in 1849 an officially unrelated company was created under the name of the Farmington Valley Railroad, which received a charter from the Connecticut legislature to build a rail line northwards from Granby 4.5 miles (7.2 km) to the Massachusetts state line.^[2][3] Soon after it opened, the New Haven and Northampton acquired a 1,000 year lease of the new company for $10,000.^[3]

Building in Massachusetts proved to be more difficult, as several railroads in that state were determined to keep the New Haven and Northampton confined to Connecticut, most of all the Hartford and New Haven.^[2] The New Haven and Northampton's charter allowed it to build in Connecticut, but it lacked an equivalent charter from the state of Massachusetts. Two more small companies were established in 1852 and promptly received charters from the Massachusetts General Court; the Hampden Railroad was to build from the state line to Westfield, Massachusetts, while the Northampton and Westfield Railroad would build from Westfield to Northampton.^[2] In 1853, these two companies merged to form the Hampshire and Hampden Railroad, the name derived from the Hampshire and Hampden Canal which was once the Massachusetts portion of the Farmington Canal.^[2] The combined line between Granby and Northampton opened in 1856, and remained independent until October 1, 1859, when the New Haven and Northampton acquired a 999-year lease of the Hampshire and Hampden in exchange for agreeing to assume $200,000 of the latter company's bonds.^[3] All three of these smaller companies were formally consolidated with the New Haven and Northampton on July 1, 1862.^[8]

In 1867, construction began on a branch from Northampton to Williamsburg. The eight-mile (13 km) branch opened in 1868.^[2]

Independent operations

The New York and New Haven Railroad's lease of the New Haven and Northampton expired in 1869, and was not renewed.^[2] From the start, the New York and New Haven had been suffering a significant loss from its lease of the Canal Line, losing between $35,000 and $45,000 per year.^[3][7] By 1860, the New York and New Haven had lost over $250,000 from the lease, while the Hartford and New Haven lost a further $120,000.^[3] Thus, the New Haven and Northampton was an independent company for the first time in 20 years. The company quickly began to expand its lines at this time, nearly immediately starting construction on an extension of the Collinsville Branch to Pine Meadow, the site of a tool manufacturer.^[6] This extension opened for traffic in 1870, and was further expanded to New Hartford, Connecticut, in 1876.^[2] Construction between Collinsville and New Hartford was along a narrow gorge following the Farmington River. It was reported that construction along the river was so difficult that the area was nicknamed "Satan's Kingdom".^[6]

In Massachusetts, the New Haven and Northampton built a branch from North Westfield to Holyoke in 1871, a distance of nine miles (14 km).^[2] Here, the company connected with the Connecticut River Railroad.^[2]

The New Haven and Northampton began a switch from iron to steel rails in 1872, which were stronger and better able to handle increasingly heavy trains.^[9]

In the early 1880s, two additional branches were built. The first was the 18-mile (29 km) long Shelburne Falls Extension, built in 1881 between Northampton and Shelburne via South Deerfield.^[2] The following year, the nine-mile (14 km) long Turners Falls branch was built between South Deerfield and Turners Falls.^[2]

Assumption of control by the New York, New Haven and Hartford Railroad

A battle for control of the New Haven and Northampton began in 1880, when the Boston and Albany Railroad, an east–west line in Massachusetts, chose a new president. The new president, William Bliss, had a plan to compete with the New York, New Haven and Hartford Railroad (formed by the merger of the Hartford and New Haven and the New York and New Haven in 1872). Bliss sought to take control of the New Haven and Northampton to secure a competing route for traffic between New York City and Boston. For the new few years, the Boston and Albany began purchasing shares of the Canal Line, driving a more than three-fold increase in share price.^[10]

The president of the New Haven Railroad was said to have learned of rumors about the Boston and Albany's plans from a mention in a Springfield newspaper in March 1881. The New Haven's executives were greatly alarmed, as "For years they had been haunted by the bugaboo of a parallel railroad between New Haven and New York, and here it was about to be materialized as a part of a new through line from New York to Boston."^[10] The executives decided to buy the shares still held by Joseph Sheffield, who controlled more than half the company's stock. Upon visiting him, Sheffield told the New Haven's representatives that he would sell to them, but only for $100 per share (equivalent to $2,682 in 2020). Despite the steep asking price, the New Haven agreed to buy all of Sheffield's shares for a total price of $1,229,800 (equivalent to $32,979,843 in 2020), much to the anger of the Boston and Albany, which had also been attempting to obtain his shares.^[10] Now having control of a majority of the Canal Line's stock, the New Haven installed new directors which supported its interests.^[10]

The New Haven leased the Canal Line in 1887, ending its independence.^[2] While the Canal Line was only mildly profitable for its new owners, the New Haven judged the costs of allowing a competitor such as the Boston and Albany or the New York and New England Railroad to take control to be far higher.^[11] The New Haven and Northampton continued to exist on paper until it was finally merged into the New Haven on October 26, 1910.^[12]

20th century

Entering the 20th century, the New Haven and Northampton was considered a secondary route compared to the parallel New Haven–Springfield Line. The first cuts to the railroad came in 1919, when the branches to Shelburne and Turners Falls were both placed out of service.^[2] While freight service resumed on the Turners Falls branch a few years later, the tracks between Shelburne and South Deerfield were formally abandoned in 1925.^[2]

The Turners Falls branch and the remaining portion of the Shelburne Extension were both abandoned in 1943, but the final four miles (6.4 km) of the former line were purchased by the Boston and Maine in 1947 and returned to service.^[2]

In 1956, the New Hartford branch was cut back to Collinsville.^[2] The Collins Company, the line's biggest customer, shut its doors in 1966, leading the remainder of the branch to be abandoned two years later.^[2][13]

Penn Central, Conrail, and abandonments

The New Haven and Northampton Railroad right of way in Plainville, Connecticut, is now owned by Pan Am Railways and serves several local industries.

The former New Haven and Northampton right of way is now a trail in Hamden, Connecticut, and bears the logo of the former railroad.

The New Haven was merged into the Penn Central Transportation Company on January 1, 1969. That year, the main line was cut back from Northampton to Easthampton, and the Williamsburg Branch abandoned in its entirety.^[2] In the middle of the 1970s, the railroad line's connection to the Northeast Corridor was severed due to low clearance under a bridge which made it impossible for modern railroad cars to access the line.^[2] Traffic to and from the southern portion of the line had to be routed via Plainville from this time onwards.^[2]

Penn Central went bankrupt in 1970, and the federal government got involved, ultimately creating Conrail in 1976. The remaining lines were included in Conrail, with the exception of the segment between Simsbury and Westfield, which was abandoned.^[2] This left the former New Haven and Northampton as two separate lines. To save the five miles between Avon and Simsbury, the state of Connecticut agreed to subsidize Conrail operations over that segment.^[2]

Conrail sold its Connecticut portion of the Canal Line to the Boston and Maine, while the Massachusetts lines went to the newly formed Pioneer Valley Railroad.^[2] The line between Avon and Simsbury was abandoned at this time, and the Boston and Maine further cut the line back to Plainville in 1991. Meanwhile, the southern portion in Connecticut was cut back to Cheshire in 1987.^[2]

21st century

In the 21st century, the remaining Connecticut portion of the Canal Line is operated by Pan Am Railways between Plainville and Southington, while the Pioneer Valley Railroad operates the remnants in Massachusetts. The majority of the abandoned right of way in Connecticut and Massachusetts has been railbanked and converted into several different rail trails, chiefly the Farmington Canal Heritage Trail.^[14]

The Connecticut Department of Transportation has identified the abandoned portions of the Canal Line between Hamden and Suffield, as well as between Farmington and Canton, as corridors which have the potential for future freight rail service.^[15]
