Physics Class, Joined by Rav Schachter, Explore the Inner Workings of Grand Central Terminal

by Shlomo Fried ('14)
On January 16th, Dr. Berliner's AP Physics class, joined by RIETS Rosh Yeshiva Rav Hershel Schachter and parent Mrs. Deborah Rosensweig, took a trip to explore Grand Central Terminal (GCT). We visited the secret M42 sub-basement 13 stories down, as well as the top floor of the terminal.
Our trip started with a descent down in the depths of the terminal through a secret elevator located right across from the lost and found room. We learned about the rotary converters that powered all the trains during WWII. The guards of this basement had orders to shoot people on sight if they accidentally came down here because by pouring just one bucket of sand onto these converters, a block of glass would be formed, sabotaging the entire process. We also learned about the system that they had in place many years earlier involving brass bells and electronic computers that would allow them to know where trains in the basement were located. However, this system became obsolete in 1922 when they started using radios to discuss the positioning of trains. We also heard about a secret little red button, which is in this sub-basement, that shuts the entire power down in GCT.
After this, we were able to go up to the top floor of GCT where we saw the control room. The control room has about 20 employees who account for all the trains in the entire system that GCT covers. After viewing this area, we went across the glass catwalks which are located right above the Apple Store in the terminal. We were met by the information booth in the center to learn about the secrets of  GCT. The first big secret is that this booth itself has a spiral staircase in its center, allowing the workers an easy exit. Also, the giant clock that sits above this booth has its own secret, which is that it is valued at ten to twenty million dollars! In addition, the entire ceiling picture of the constellations in the sky is a mirror image of what it should be, while the dimensions of the staircase that sits in front of the Apple Store are one inch shorter than all the dimensions of the original staircase.
This was an amazing trip, which really let us get firsthand accounts of the inner workings of one of New York City's greatest landmarks and tourist attractions. Special thanks to Dr. Berliner for arranging, and to Rabbi Schachter and Mrs. Rosensweig for joining. [gallery]
