New timetables for the Long Island Rail Road are effective Monday, with extra holiday season train service and changes in East End travel.

The LIRR said the new schedules will be in effect through March 6.

Other changes include daily train service from Montauk and weekend train service to and from Greenport.

The new schedules also reflect adjustments to departure and arrival times of off-peak and weekend trains to accommodate track work on some branches, the LIRR said in a news release.

The LIRR will operate additional early afternoon eastbound trains on Thanksgiving Eve, Nov. 23, Christmas Eve and Dec. 30, the Friday before New Year’s, for customers looking to make early getaways from work.

On Thanksgiving Day, extra trains are scheduled for the Macy’s Thanksgiving Day Parade.

On Black Friday, Nov. 25, the traditional start of the holiday shopping season, the LIRR will operate on a regular weekday schedule.

As a bonus, off-peak fares will be in effect for the extended Thanksgiving weekend, Nov. 24 to Nov. 27, and the family fare discount will be in effect all four days. That means children ages 5 to 11 (with a limit of four children) can ride one-way for $1 when accompanied by a fare-paying parent or guardian. Weekly and monthly ticket holders pay just for the kids and, as always, children under 5 ride free.
