This secret underground chamber deep under Grand Central Terminal played a crucial role during World War II.
Discover what has been hidden and protected inside New York City’s Most Secret Basement.
What was hidden deep beneath New York City’ Grand Central Terminal and why Nazis wanted to destroy it during World War II?
The secret underground chamber – almost as big as Grand Central Terminal itself – contained rotary converters to transform 11,000 volts of alternating current to direct current to power all the trains above. It was – so to say – the beating heart of the entire northeastern United States metro rail network.
Of course, when the USA decided to join the Allies, Hitler sent German Nazi soldiers to destroy this underground control center. Luckily, they did not succeed and the US weren’t delayed from joining the war.
