Kids and adults work together to uncover the secrets of this amazing train station.

Go nuts in the Whispering Gallery, spot surprises in the stars in the “sky,” find TV celebs in the fabulous food court, stand on fish under an upside-down tree in the Grand Central Market, learn the arrival time of a “ghost” train in the “Kissing Room,” see where a missile pierced the ceiling, count creepy critters trying to invade a “ship,” and find funny details in the latest exhibit inside the Transit Museum Gallery.
