In 1983, Metro-North took over operation of Grand Central Terminal, and soon after the railroad began a systematic program of repairs and capital improvements, including a $4.5 million project to replace the leaking roof and skylights.  This urgently needed work helped stabilize the building and enabled Metro-North to develop a long-term strategy for Grand Central.    

In 1988, Metro-North commissioned a master revitalization plan from Beyer Blinder Belle -- the architects responsible for the restoration of Ellis Island.  Metro-North then asked retail specialists Williams Jackson Ewing to prepare a master retail plan to address amenities and services in Grand Central.  In April 1990, a $425 million Master Plan for Grand Central Terminal was presented at a public hearing and subsequently adopted in concept by the Metropolitan Transportation Authority.  This significant decision was followed by an investment of $160 million in utility upgrades, Main Concourse improvements, and structural repairs.  The former Main Waiting Room was also restored in accordance with the new Master Plan, and was inaugurated as a public exhibition and special events space in 1992.
