CT Rail operates two commuter rail lines: the
Hartford Line and
Shore Line East.
Hartford Line The
Hartford Line runs between
New Haven Union Station in New Haven, Connecticut and
Springfield Union Station in Springfield, Massachusetts, running through Hartford, Connecticut. Ten CT Rail round trips operate on weekdays, and six on weekends. This service is supplemented by eight additional roundtrips run by the
Amtrak Hartford Line, which operates along the same route. CT Rail Hartford Line tickets are accepted on the Amtrak Hartford Line, and vice versa; however, the
Vermonter inter-city service does not participate despite running along the same route. This line is a joint venture between the Connecticut Department of Transportation and the
Massachusetts Department of Transportation (MassDOT). The line is not electrified and is a mostly double track route that uses diesel locomotives. Service began on June 16, 2018. The majority of the Hartford Line's route is along the New Haven–Springfield Line, with two stations in New Haven, Union Station and
State Street, being on the
Northeast Corridor.
Shore Line East CT Rail's
Shore Line East commuter rail service runs between
New London and
New Haven. Ten round trips operate on weekdays, and eight on weekends. Limited weekday service extends along Metro North's New Haven Line to
Stamford. When service initially started along the line on May 29, 1990, Shore Line East commuter trains were intended to be a temporary measure in order to reduce congestion along
Interstate 95 during a highway construction project. However, the service was made permanent due to more ridership than initially anticipated. Pre-COVID, the line had an average daily ridership of about 2,100 riders. It runs along the
Northeast Corridor for its entire length. Since May 2022, Shore Line East has used
Kawasaki M8 electric multiple units to provide service on the line. == Rolling stock ==
