The T&G made a connection from the V&M at Greenfield and was
created to reach Troy/Albany, New York via the southern tip of the Green
Mountains, specifically Hoosac Mountain. At North Adams in the very
northwest corner of Massachusetts, ground was broken on January 8, 1851
for the construction of Hoosac. The project was slated to cost
$2 million and used a new mechanized stone cutter. However, it proved a
poor and unreliable design. After five years and little accomplished the railroad hired noted engineer Hermann Haupt to continue the project. Despite Haupt's recognition and time working for the Pennsylvania Railroad there had been little accomplished by 1861 when he quit to work for the US Military
Railroads during the Civil War. At the time the tunnel had just 500
feet completed on the east end and 1,810 feet on the west end.
The railroad's efforts were also being hampered by the Western Railroad, which attempted to block the project fearing the competitive edge the Troy & Greenfield would gain if the tunnel was completed. The project was also being hampered by the rock itself which was a combination of soft, crumbly material and very hard gneiss and quartz. Without Haupt's services the operation almost literally shutdown. A year later, on August, 18 1862 the Troy & Greenfield fell into bankruptcy as it was unable to pay down its debt. As a result, the state took over the line and decided to continue construction of the Hoosac Tunnel. In 1868 the legislature provided for $5 million to help see the project completed.
By the early 1870s it was nearly finished and officially opened on February 9, 1875. By this time the tunnel had cost some $20 million, killed 193 workers, and was 4.75 miles in length; the longest such bore in the North America at the time. Three years after it opened the Fitchburg Railroad merged the T&G into its system and on July 11, 1900 the entire route became another division of the growing Boston & Maine Railroad. With more resources and understanding the tunnel's exhaust issues the B&M would electrify the Hoosac in May, 1911, which also helped to reduce operating costs since the motors were more powerful than the steam locomotives. The standard boxcab electrics used by the B&M remained in use for more than four decades. On September 5, 1940 the new Electro-Motive Corporation, a General Motors Division, tested their new model FT demonstrators on the B&M.

The railroad was thoroughly impressed as a the A-B-B-A #103 FT
set carried an 83-car train that weighed some 4,500 tons between
Mechanicville, New York and Boston in record time. A few years later in
1943 and 1944 the B&M purchased 48 FT units, or 12 A-B-B-A sets,
and began the process of shutting down its electrification of the tunnel, which was completed by 1946. To compensate for the diesel
exhaust the company installed a better and more efficient ventilation
system. In 1957 the tunnel was reduced to a single track for better
clearance (and remains so to this day) and by November 28, 1958 the
final passenger train used the bore. Today, the while the route to
Albany no longer sees the heavy freight use it once did it is still an
important part of the Pan Am Railways system today.
