New York City has a lot of secrets.

There's a so-ho loft known as the New York Earth Room, which contains nearly a quarter

of a million pounds of dirt, installed by an artist in 1977.

There's a World War I fighter plane sitting on top of a 26-story building on Water Street,

and there's even a 25-foot waterfall in a park on East 51st Street between 2nd and 3rd

Avenue.

But few are aware that there's a deeper secret, one that's tucked away where most will

never see it, and it all starts back around 1910 when construction began on Grand Central

Terminal.

At the same time, they built a power plant that supplied energy to the terminal and

surrounding tracks, complete with its own set of tracks and a platform so that cargo

trains could carry the plants' waste away.

But in 1930, the plant was torn down, and a hotel was built on the same spot.

It was a clean start with everything built from scratch.

Well, except for one thing, they left the tracks and the platform underground, and even

connected it to the hotel by way of an elevator.

In beginning with Franklin Delano Roosevelt, American presidents have used the secret train

station, hidden away beneath the iconic Waldorf Historia.

There's something powerful about a buried secret.

From the legends of pirate treasure beneath the sands of some tropical island to the academic

work of tireless archaeologists, the idea that things can be hidden beneath our feet

has never been up for dispute.
