Sometime during the 1960s, high-level platforms were added to the station, with a white stucco wall between the platforms and station house containing a blue sign with white lettering reading "LONG ISLAND RAIL ROAD" on top and "NEW HYDE PARK VILLAGE" on the bottom.

[8] In October 1979, work began on a $525,000 project to extend the platforms at the station to accommodate ten-car trains.

[9] As part of the Main Line third track project, the New Hyde Park station received significant upgrades, and Platform B was relocated.

Canopies, benches, signage, and security cameras were installed, and the new platforms are heated to facilitate snow removal.

[10][11][12] Additionally, the grade crossing at New Hyde Park Road was eliminated and replaced with a vehicular underpass.

[14] On October 24, 2020 the 12th Street grade crossing at the west end of the station was closed permanently to traffic, and in early 2021 was replaced with a pedestrian underpass.
