It appears that Friday June 8th is the last day of the current Amtrak schedule on the Springfield line. On Saturday June 9th, it appears Amtrak will be making its schedule changes on the line including some additional service that was made possible by the New Haven - Hartford - Springfield program. The weekend schedule only involves a couple changes, most of the big changes begin June 11th, the first day of the new weekday schedule. The Hartford Line commuter service starts the following week on June 16th. On that day the state of Connecticut will begin running its new "CTrail" dedicated commuter trains and the Amtrak fares between the Hartford Line commuter stations will change to match the Hartford Line fares on the 16th - intercity fares to destinations beyond NHV remain the same. These additional trains can now be seen on Amtrak's booking site but it appears they are still updating the system as the train numbers don't yet appear. Most changes are positive and add additional service and connections in New Haven. Only two losses of service: one is a loss of connection to train 93 for Windsor, Windsor Locks, and Springfield - 493 shuttle is going away. A Hartford-terminating CTrail southbound train will replace 493 in its timeslot and two new Amtrak Shuttles will launch an hour earlier and two hours later (471 and 473.) Hartford and south can still connect to 93 using the new CTrail train. Presumably, folks that were already booked for 493/93 June 11th and later will get swapped to either 471/171 or 473/173. The other service loss is Berlin and Wallingford are being cut from the Vermonter beginning that week. Folks can view

As seen on there, in addition to Amtrak's new trains the CTrail trains also allow a couple of additional Amtrak connections to be made at New Haven and they are listed there (obviously with no connection guarantee as they aren't operated by Amtrak.)
