Haven. Hartford Line began on June 16, 2018. Initial Hartford Line service consisted of eight weekday round trips (four New Haven–Hartford and four New Haven–Springfield) and nine weekend round trips (six New Haven–Hartford and three New Haven–Springfield). On September 10, 2018, as part of a schedule change made to Hartford Line trains, all Amtrak Shuttles and Northeast Regionals started stopping at New Haven's State Street station. (The Vermonter makes only limited stops between New Haven and Springfield.) Amtrak adopted the Hartford Line name for use on the trains it operates on the corridor and retired the Shuttle designation in September 2019. Service was reduced in 2020 during the COVID-19 pandemic; service levels were restored to pre-COVID frequency on April 25, 2022. Most service will be replaced by buses from July 18 to September 9, 2022, during canopy roof replacement at Hartford Union Station and slope stabilization work in Windsor. Valley Flyer pilot program On June 12, 2018, Massachusetts Governor Charlie Baker announced that two daily round trips 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. Two round trips are offered on weekdays and one on weekends with southbound trains in the morning and northbound in the evening which complement Amtrak's existing daily service on the Vermonter. Additionally a reverse round trip operates between Springfield and Greenfield on weekends only. Operation The local Hartford Line trains are numbered in the 400 series, usually denoting by the last two digits which Northeast Regional train the Hartford Line train is connecting with. Trains terminating in Springfield carry the Hartford Line name, while trains terminating in Greenfield carry the Valley Flyer designation. Typical consists run in push-pull configuration with a General Electric P42DC locomotive pulling an Amfleet coach and a 9600-series ex-Metroliner cab car. Normally the ex-Budd Metroliner leads northbound trains, while the GE Genesis usually leads most southbound trains. Crew bases are at Springfield and New Haven, with diesel locomotive servicing taking place at New Haven. The Valley Flyer trains account for two weekday round trips and one weekend round trip. Southbound Valley Flyer trains require an equipment move from the crew base and equipment layover yard at Springfield Union Station to the Olver Transit Center in
