A famous building in New York City is turning 100 years old. A year-long celebration is planned for Grand Central Terminal, which is usually called Grand Central station, the sixth most-visited place in the world.

The huge building has not changed much since it opened in February, 1913. About 750,000 people pass through Grand Central every day. Some just come to look at it, others to visit the stores. But most are there to catch the trains that enter and leave from the station. It is the largest train station in the world. There are 67 train tracks, all of them underground.

The main part of the building has large, arched windows, a jeweled four-sided clock and ticket windows. Grand Central has been seen in many movies through the years. Dan Brucker is with the New York Transit Authority, which operates the station. Dan Brucker has worked for the transit authority at Grand Central for 30 years. In all those years, he has not lost his interest in the building.

Justin Ferate, a historian, has been giving tours of Grand Central Station for 30 years. He says the station was designed to make travel a pleasure.

“Why people don't run into each other in Grand Central is simple: each block of stone in Grand Central is the length of your leg. Each block of stone in Grand Central is the length of your arm. Each block of stone is a different color, so it’s a checkerboard, based on you.”   

A ten-year-long fight against plans to build a huge office building over Grand Central in 1968 helped create the modern preservation(保护) movement. Now, no one would think of changing the beauty of the station.
