The names "Shuttle" and "Springfield Shuttle" are being discontinued. Most trains now will carry the name "Amtrak Hartford Line" to mirror what CTDOT refers to them as (and to distinguish them from CTrail Hartford Line trains which also operate on the line.) The CTrail and Amtrak Hartford Line trains together provide the Hartford Line commuter service. Trains continuing past Springfield to Greenfield will be known as "Valley Flyer" trains. This is now reflected in the reservation system.
