On June 12, 2018, Massachusetts Governor Charlie Baker announced that two daily round trip Amtrak Hartford Line trains (then called New Haven–Springfield Shuttle) would be extended to Greenfield in 2019 as a pilot program.

On weekends, one similarly scheduled New Haven-Greenfield round-trip is offered, in addition to a reverse round trip between Springfield and Greenfield.
