At Lynbrook, trains continued west to Hunters Point, Queens, operating on tracks built by the South Side Railroad of Long Island (which had merged with the LIRR prior to the NY&LB service).

[9] A five-mile (8 km) extension to Point Lookout, New York owned by the Long Beach Marine Railway Company existed between 1881 and 1895.

Electrification of the main tracks from Valley Stream to Long Beach was finished in September 1910, with the freight sidings being electrified between 1928 and 1930.

The Long Beach Branch's familiar orange color scheme (    ) was first implemented on May 20, 1974 as part of the MTA's Form 8 timetable.

[13] Partial rail service was restored on November 14, when a diesel-operated shuttle began operating between Lynbrook and Long Beach on a modified weekday schedule.

[17] The projects also include the raising of the Oceanside, Oil City, and Long Beach substations 15 feet (4.6 m) off the ground and an emergency generator for the Wreck Lead Bridge over Reynolds Channel.
