The changes aim to improve on-time performance during peak hours as well as accommodate upcoming track and infrastructure work.
The Devon Bridge work will be completed, and the temporary Devon Transfer station will close.
Waterbury Branch customers will once again transfer at Bridgeport.
To combat Stamford train congestion during the later peak hours, the 7:04 p.m. local to Grand Central will depart three minutes later. Six morning peak trains will also move 1-2 minutes to match up with current performance.
Commuters can check timetables for adjustments. They can be found at all stations including Grand Central, on the Train Time App, as well as at this link.
