The Long Island Rail Road is adding trains Friday afternoon to accommodate passengers observing Yom Kippur, and is also performing some track work that will affect both train riders and motorists this weekend.

The LIRR is offering nine additional trains from Penn Station on Friday for customers going home early for the holiday. There will be three extra trains on the Babylon and Port Jefferson branches, two on the Port Washington Branch and one on the Far Rockaway Branch.

The LIRR is also replacing trains with buses on the Far Rockaway branch from 6:15 p.m. Saturday until 12:05 a.m. Monday. The closure is to allow crews to resurface switches, replace rails and improve drainage on a stretch of track between Far Rockaway and Valley Stream. Customers riding the line during the outage are advised to allow up to an extra hour of travel time.

And a project to upgrade the Atlantic Avenue grade crossing in Oceanside this weekend will require closing the road and detouring traffic from 9 p.m. Friday until 11:59 p.m. Sunday. The road will be closed again on the weekend of Oct. 15 and 16 as the project is completed.

The project includes replacing rubber crossing pads with longer-lasting and smoother concrete, rebuilding the track bed and replacing wooden track ties with concrete track ties.
