Valley Flyer (Amtrak train)

The Valley Flyer is a train service run by Amtrak between New Haven, Connecticut and Greenfield, Massachusetts along Amtrak's New Haven–Springfield Line and the Massachusetts Department of Transportation's Connecticut River Line. 
"Valley Flyer" trains meet "Acela" and "Northeast Regional" services at New Haven Union Station where passengers can typically make a cross-platform transfer between trains. Departures on the Valley Flyer are timed to enable day trips between the Connecticut River Valley and New York City possible. 
South of Springfield, the "Valley Flyer" complements the Hartford Line commuter rail service operated by the Connecticut Department of Transportation and Amtrak's Hartford Line service. North of Springfield, it complements Amtrak's Vermonter, offering travelers in the Valley three daily round trips on the Connecticut River Line.

On June 12, 2018, Massachusetts Governor Charlie Baker announced that two daily round trip trains (then called "New Haven–Springfield Shuttle") would be extended to in 2019 as a pilot program. By February 2019, the two-year pilot was expected to begin in June 2019; however, by that May it was delayed to later in the year. On August 30, 2019, the "Valley Flyer" program began.
