Jamaica Station got a makeover from the Metropolitan Transportation Authority for its 100th birthday.
The Queens landmark has long served as a transfer point between Long Island and the city.
The $8.5 million project included restoring the building's crumbling exterior, and refurbishing the ticket office and waiting area.
Other improvements are in the works, including getting Long Island Rail Road customers directly to Grand Central Terminal and East Midtown for the first time.
The MTA says the historic hub is used by 300,000 commuters a day.
