I learned SO MUCH on this tour about the station. This is just some of the most interesting stuff my guide talked about. He teaches seminars, gives lectures, and does tours for all kinds of stuff. Check out his website if you're interested.
So, this is a portion of the notes I was frantically scribbling in my Moleskine and will now try to decipher for you:
We were standing in the main terminal and were told to look in each of the windows - there were statues carved depicting all sorts of symbols of travel - wheels, carts, luggage. boxes, cars, trains, etc. Then, on the ceiling, as you may have seen in the video clip, there are constellations painted onto a night sky - the most timeless and dependable travel companion in the history of Z world!
(I apologize that I don't have tons of photos to accompany this info. I was caught up in my writing and trotting along at his heels asking all sorts of questions during this time.)
The tour guide, Peter, really stressed how a building speaks to us - how architecture serves a purpose and tells a story. When you entire Grand Central Station from Lexington Avenue, the ceiling is low, the walkway is narrow. The building is telling you to hurry up, to get out of the way, to enter or exit quickly depending on your direction. As you walk in to the terminal, things start to open up, you emerge into the main terminal, and the light pours over you. This is meant to feel like a spiritual experience - I tried to be receptive to it and it really did feel like being lifted up, kind of cool. Stairways on each end of the terminal are fashioned after those in a Paris Opera house. When you enter this station you enter in style. It was fascinating to watch the people ascending/descending the stairs. Nearly every single person would slow his/her pace and at least 80% of the people would pause for a moment to take in his/her surroundings. It was so interesting. That's the way the stairs were intended to function.
The vast windows on each end of the terminal have been said to be the greatest in the world. There are catwalks on the outside where you can see folks walking to work or men working on the windows cleaning them. New York gets HOT - and how would you go about cooling a place that hosts 500,00 bodies per day? You simply open the windows. It's like air conditioning. New York also gets unforgivingly cold in the winters with harsh winds. How do you heat this place? You close the windows and allow those same 500,000 bodies to emit 98 degrees of heat as they pass through the terminal. It heats itself. Remarkable, no?
This place was going to be demolished in the 50's. In 1995 a major renovation happened. The entire terminal was cleaned from top to bottom by hundreds of men and women, scrubbing away every day. There is a single rectangular piece on the ceiling where the decay and dirt was left as a witness of those times - I tried to get a photo but it was so high up, I couldn't get a good one.
The terminal went through a phase where huge Kodak pictures were strewn across in 40ft banners and that huge clock was installed, but those banners were taken down and the clock was removed - now only a flat-screen that occasionally flashes advertisements. This was to preserve the art of the humans moving through the space - to make that natural phenomenon the singular living, breathing creative process to occur there.
You can imagine how many people arrived here from all around the country on long-distance trains. In the area of the station where these folks arrive, they were vomited into a corridor that has incredibly low ceilings and narrow hallways - again, the message is clear: keep moving, knucklehead, and learn how to walk faster, and oh yeah - welcome to New York City. 270 of these trains would arrive in one day - about every 3 to 5 minutes a new train would pull in. It would dispose of its passengers and then wait in another part of the tracks for a few hours for people to come back and get things they forgot, etc. This level of long-distance arrivals is an entire floor above those who arrive for their commute. Why? Because commuters are LATE. And these exhausted travelers are slow, lost, and in the way. Smart, huh?
Once the long-distance travelers instinctively move through the corridor and past the "Kissing Room" where families/friends could reunite, their eyes fall upon shops and open hallways. "Heyy, relax, spend some money, have a cupcake." A warmer welcome at last. Then you can either walk up the ramp out to a taxi stand or walk straight onto the most expensive subway system in the world. These people were immediately granted total access to the City.
A hotel was built on top of the station, but there was no need to go out of the way to accommodate those who arrived - this train station was such a success that hotels opened up all over the block for the new arrivals. So, Grand Central had a bunch of space to use. The CBS radio station found its home in a portion of this station, as well as tennis courts, and the Campbell Apartment, which is now home to the most elegant cocktails in all of New York City. That lounge was just exquisite, but so dimly lit you couldn't get a proper photo.
This is some interesting stuff, and then I'll wrap it up: the trains are located 2 stories below street level. The commuter level, again, is 3 stories below street level. All of these terminals are accessible without stepping on a single stair - it is all connected by ramps - but as we were walking I didn't notice for one second whether we were going up or down, because the inclines are so slight... It was fascinating. Hence, the station is called the "Great, stairless terminal." And why? Because steps slow you down. Move, move, move!
60 tracks across, 2 stories underground, it spans from 42nd Street to 50th and from Lexington Avenue to Madison... In 1929 the entrance to Grand Central looked like this (you'll recognize those massive windows from the photo I posted of inside the terminal):

(Now the streets are level with the one shown here - there is no ramp)
Land is infinitely precious in New York and there was no time to waste! ... Streets were built and joined by metal plates. Buildings were built upon steel beams. The European-style Park Avenue turned into one of the most expensive streets in all of America, and millionaires were moving out of their mansions into apartments on 5th. Everyone wanted in. The richest, most intelligent people in America (and really, the world, because of its draw and attracting folks from every country on the planet who could make their way here) were now living in this area on top of blocks and blocks of trains.
While standing on the sidewalk at the end of the tour, I looked down and saw the jagged cracks and splitting concrete. This is due to the hundreds of trains passing beneath my feet, and beneath the streets of New York all day every day, rumbling and tumbling through the earth, taking all 8 million people of New York City to their destinations.
