The Housatonic Railroad (/ˌhuːsəˈtɒnɪk/ HOOS-ə-TON-ik; reporting mark HRRC) is a Class III railroad operating in southwestern New England and eastern New York. It was chartered in 1983 to operate a short section of ex-New York, New Haven and Hartford Railroad in northwestern Connecticut, and has since expanded north and south, as well as west into New York State.
The Housatonic Railroad was also a company chartered in 1836 and leased by the New Haven in 1892. It followed much the same route as the current company, but did not run west into New York.
