New Hartford Line commuter rail service on the line began on June 16, 2018.  Expanded Amtrak Shuttle service on the line launched one week earlier on June 9, 2018.  Connecticut DOT provides eight round trip commuter trains on weekdays under its new CT rail branding that are operated by its new contractor, a joint venture between TransitAmerica Services and Alternate Concepts Inc.  Five of these trains operate between New Haven and Hartford, with the other three running the whole line between New Haven and Springfield. Amtrak has added three new Shuttle round trips on top of its previous service. This brings the total round trips on the line to sixteen between New Haven and Hartford, with eleven of them operating along the full line to Springfield. On weekends and holidays, CT rail operates four New Haven–Hartford round trips and two New Haven–Springfield round trips. Amtrak continues to offer its existing weekend service with some minor schedule changes. Together, twelve–thirteen round trips are offered on weekends.
