Riders will notice schedule adjustments along the Babylon, Montauk, Port Jefferson, Port Washington, and Far Rockaway branches.
Some trains will make fewer stops, others will make additional stops, and some will have departure times changed by a few minutes.
The update comes as the MTA reacts to feedback from riders after a major overhaul of LIRR timetables in February due to the addition of Grand Central Madison.
