This is in addition to the 56 trains added last October.
The added trains will mean more off-peak and weekend service, as well as faster service for weekday customers.
The extra trains run in Westchester and Fairfield counties.
Also, nine more weekend trains have been added on the New Haven Line and an extra 85 weekday and 22 weekend trains are running on the Hudson Line.
The Harlem Line will have an additional 65 weekday and six additional weekend trains.
