Grand Central Terminal-Walkways-Windows-Secrets

One of the things we learned on the Untapped Cities tour of the Secrets of Grand Central was that there are walkways in the massive windows of the terminal! This photo was shot by Mandeep Bedi of Taste Architecture on the tour. If you look closely, you’ll see someone crossing right between the first zero in 100. The walkways connect the offices above Grand Central so the employees don’t have to walk through the busy terminal, according to Untapped Cities tour guide Tamara Agins.

On a special visit (not on our public tour), we explored the top level walkway itself, which is of glass cinderblock. You need a special key pass to get into the hallways normally.

    During a trip into NYC to see the Allman Brothers play at the Beacon around ’95 a friend and I were very lucky to be given a private tour of the glass walkways. The friend who gifted us this tour happened to be working at GCT at the time. And he happened to have keys in his pocket to show us around. It was a GREAT way to spend time before catching the last train back to CT and after a superb show at another NYC iconic place, The Beacon Theater. I have told the story repeatedly all the while knowing that the person subjected to my overzealous storytelling would never know the feeling of being there, without actually being there. It was awesome.

    While there we did try out the Whispering Gallery’s mysterious acoustics…. it was something I hadn’t experienced since I was kid on a school field trip to a place that has long left my memory. This experience, circa 1995, at Grand Central Terminal will never escape my memory. Ever. As a matter of fact, and if opportunity surfaces, I will pay the $30 for a tour through the terminal, gladly. Thank you for this great piece.

      Hi Cat, thank you for your story! How cool you got to see the glass walkways too! The Beacon is indeed an amazing NYC spot too.

    Hi Michelle, good point? I’ll thank you to stop staring at the top of my head 🙂 I dont know the architectural history of transparent glass blocks other than that their popularity exploded post-war as a means to allow light yet retain privacy (exterior bathroom walls in particular)

    You’re most welcome for my meager contribution. Please permit me to thank YOU and everyone else who writes for this site. Anthony

    I’ve read somewhere that prior to WWII the public was admitted to these walkways for the princely sum of a nickel. During the late 70’s and early 80’s I ventured all over this wonderful building and transversed these catwalks. I’m surprised to have never seen mention of the fact that the floors are comprised of glass cinderblock!

    More worthless trivia is that the Kodak display featured the world’s largest transparency and that the marble nearest the Vanderbuilt Ave entrance is mildly radioactive.

      You make a good point! We recently got a special visit to the walkways and can confirm – they are indeed glass cinderblock (we added more photos above)! Thank you for the tip about the Kodak and marble, we love this kind of stuff!

    That has to be a bitchin’ view. Thanx for the tip.

    These walkways have been in a number of thrillers over the decades. Parallax View maybe?
