Reason #2 I Love New York City

Oh yes it's two for Tuesday! So here's Number two of Why I love New York City:
As I said it's a two-fer.
This is about the subterranean New York I Love.
The Subways, the Tunnels and passageways most people don’t know about and most people never even heard about.
There once was a pedestrian tunnel under Sixth Avenue between 34th and 40th Streets. ...
When the Sixth Avenue subway was built, the tracks had to be fairly deep below the street surface in order to pass under existing subway lines (42nd Street Shuttle and BMT Broadway subway). Rather than spending the money to backfill the excavation, the space was left open and the walkway built above the track level.
There were intermediate stairways to the street at 36th and 38th Streets – (now all sealed) because it is rumored, some murders had been committed there.
It used to be possible to walk underground from Bryant Park all the way to 8th Avenue and 31st Street and I used that tunnel many times, especially when the weather was inclement.
When the subway station at 6th Avenue and 34th Street was rehabilitated a few years ago, the turnstiles/ fare controls were relocated blocking the free access route. They would have to be shifted again, at considerable expense, to create a clear passageway outside the fare controls should the walkway up to Bryant Park be reopened.”
If the Sixth Avenue and Gimbels’ tunnels were to ever be reopened, it would be possible to walk underground from Bryant Park to Penn Station – and eventually all the way to the Hudson Yards development.

In the opposite direction beneath Grand Central Terminal (don’t ever call it Grand Central Station!) there’s another, even more interesting tunnel.
Now you might think GCT should have it’s own day among the thousands of reasons I Love New York City … but there's this:
Lying forgotten, two hundred feet below one of America's most iconic buildings lies the closely guarded secret of a President some say was one of our best. But he was a Politician and they all have their secrets. Franklin Delano Roosevelt’s secret railway train sits rusting away Hidden under Grand Central Terminal aside the little known Waldorf-Astoria platform, which was known by Grand Central staff as the Roosevelt Platform. Roosevelt used the train to hide the fact he was in a wheelchair and the hulk that was once part of a secret kept from the American public that their President was disabled. The platform is directly under the Waldorf Astoria and after Roosevelt's 6000 horse powered diesel train would pull up on the tracks it would let his personal car out of the side. The car would then drive off the dark and secret platform into an elevator which would take it directly into the Waldorf Astoria garage.
This space vast was unknown to the outside world until the late Eighties.. and you can learn more here: http://www.dailymail.co.uk/news/article-1358385/Rusting-deep-Grand-Central-station-armoured-train-helped-heroic-President-Roosevelt-polio-secret.html#ixzz3O5Ovu5tw
