The New Haven to Springfield commuter rail service that’s scheduled to begin in 2016 will be called the Hartford Line, said Gov. Dannel P. Malloy, who announced Friday that station construction will start this fall in Wallingford, Meriden and Berlin.

Running a high-frequency schedule of trains along the Amtrak route paralleling I-91 will get traffic off the highway, reduce workers’ commute time, and encourage new retail and housing development around the stations up and down the line, according to Malloy and the state transportation department.

The single track carries about six long-distance Amtrak trains each way daily, chiefly aimed at feeding its Northeast Corridor service between Boston, New York City and Washington, D.C. Connecticut plans to add a second track along most of the route, and run 12 to 17 trains a day, mostly for commuters.

The Hartford Line service will link Connecticut River Valley communities with more than a dozen others in New Haven, Fairfield and Westchester counties.

Workers have been installing signals and underground cables along the New Haven-to-Hartford-to-Springfield line, and will now begin construction at three key stations. They’ll add high-level platforms on both sides of the track, overhead pedestrian bridges with new elevators, snow-melting systems for the platforms, and public address and video surveillance equipment.
