Grand Central Terminal
Grand Central Terminal covers 48 acres and has 44 platforms, more than any other railroad station in the world. Its platforms, all below ground, serve 30 tracks on the upper level and 26 on the lower, though only 43 tracks are currently in use for passenger service. The total number of tracks along platforms and in rail yards exceeds 100 as most previous tracks that are not in regular use are used for the rail yard. -from Wikipedia
