MTA has posted the new Metro-North Schedule, Effective October 5th, to their website.
The changes are minor.

There are no schedule changes to the Harlem Line.

On the Hudson Line:

“With the completion of concrete tie installation between Cold Spring and New Hamburg, weekend and daytime off-peak train schedules will return to their pre-April times. This change will allow for faster travel times of up to five minutes for most off-peak Upper Hudson Line customers.”

New Haven Line Customers will see the bulk of changes:

• Weekdays on the New Haven Line, the 5:48 PM train departing Grand Central, which currently terminates at Bridgeport, will now make additional stops at Stratford, Milford and New Haven, where it will arrive at 7:36 PM. This change improves the frequency of service between Stamford and New Haven during the evening rush hour.

• The 5:30 PM train departing Grand Central, which currently terminates at Old Greenwich, will now operate to Stamford, where it will arrive at 6:29 PM, allowing customers from local stations along the New Haven Line to connect with the 6:32 PM train at Stamford (which is actually the newly extended 5:48 PM train from Grand Central to New Haven).

• We’ve added midday service to the Danbury Branch. A new train departs South Norwalk at 11:11 AM and arrives in Danbury at 11:58 AM, and a new train departs Danbury at 12:42 PM and arrives in South Norwalk at 1:29 PM, letting you connect with a 1:38 PM train to Grand Central. Adding this new service requires adjusting other midday train times by up to 60 minutes.

• Weekends on the Waterbury Branch, we have reconfigured our schedule, allowing us to increase service from four round-trips a day to five. This requires moving other weekend trains up to 87 minutes earlier or later, so check a timetable for details.

• The 11:18 PM train departing New Haven will now leave at 11:38 PM on weekdays and weekends. The 12:25 AM connection at Stamford will also depart later, at 12:41 AM. Finally, with the completion of concrete tie installation between Milford and New Haven, weekend and daytime off-peak train schedules will be adjusted back to their pre-April times.
