Everything about Grand Central Terminal (GCT), conveniently locatedin the heart of Manhattan, is remarkable. On an average day, 700,000people pass in and out of it. The information booth in the Main Concourse(the huge room that is the focal point of the building) gets as many asa thousand visitors an hour. Standing beside it, you feel that if you stoodthere long enough you would eventually see every person you have everknown in your life. “It’s the town square for eight million people,” saysGCT spokesperson Dan Brucker. “If people get separated in the city, they’llmeet at the information booth.”

GCT’s art and style reflect the great economic success of railroad companiesbefore the growth of car and air travel. You could spend years in GrandCentral before you discovered all secrets: its tennis courts, its hiddenrailroad cars, its private ground-floor apartment (now a bar). Nine storiesbelow the lowest floor that the public gets tosee is a basement known as M-42. Bruckerexplains, “This is not just the deepest and thebiggest but the most secret basement in thecity. During World War II, there were shoot-to-kill orders if you showed up down here?”It was where the power came from tomove the trains carrying soldiers.Today, one box in the basement holdsa small red button, about the sizeof a coin. Above it is written“Emergency Stop.” If you pressedthis button, says Brucker, you could“make 125,000 people latefor dinner.”

Above the ground, the Main Concourse features a ceiling painted to30 look like the night sky, with stars shining down. Over the years, smokeblackened this beautiful ceiling. Although people thought smoke fromtrains was the cause, it was actually tobacco smoke! However, it has sincebeen cleaned and now shows its original beauty.

In the name of modernization, plans were made to destroy GCT in the1960s. However, many people objected, and finally New Yorkers decidedGCT was worth saving. In 1976, the U.S. government agreed. It madeGCT a National Historic Landmark, recognizing its importance forall Americans and ensuring its continued protection. Once threatenedwith destruction, Grand Central Terminal continues to give pleasure topassengers and sightseers in Manhattan.
