103 years ago today, the world’s largest train station was inaugurated in New York City. It took 10 years to construct Grand Central Station, the gigantic, multi-level railway cathedral. The station quickly became one of the most famous buildings in New York. With some 500,000 visitors a day, Grand Central remains the city’s busiest building today. All long-distance transit is handled on the upper floor, regional traffic on the lower level. The train station is known for its huge waiting rooms and its excellent shopping. In 1978, the New York landmark only narrowly escaped demolition after a U.S. Supreme Court ruling, after which it has been completely renovated.
