I have never been to Manhattan, and I am confused about one thing: How does
the Grand Central Terminal tunnel work? I've seen photos of this building,
but all around it there seem to be old steel overpasses. What are these for?

Grand Central's two-level underground railway yard and tunnel were
originally an ordinary open-air terminal station, until, in 1913, the
completion of electrifying of the railway network and the new terminal led
also to covering of the rail yards, and renting out the air rights above the
tracks for development. The enormous weight of the surface and buildings
above is supported on steel platforms. The
railway tracks from the station run in a tunnel underneath Park Avenue until
they surface at 96th Street to beautify El Barrio...
As the Terminal (together with the Helmsley
Building and Met Life Building) blocks Park
Avenue, the traffic has to be directed through and around these buildings
between 42nd and 46th Streets. Two steel bridges carry the traffic over 45th
Street, and 41st and 42nd Streets are spanned by the Pershing Viaduct in
front of the station. ED

I also suggest purchasing the video on Grand Central Terminal from A&E's
History Channel which was shown all day long in the Vanderbilt Room of the
terminal a few months ago as the rehabilitation of the building was nearing

Also, this from The New York Times:
"The original New York and Harlem Railroad first ended at 90th Street in 1834,
until a tunnel was cut in the East 90's under what is now called Carnegie Hill
three years later. Most of the rest of the track, from 42nd to 90th Street,
ran in an open cut, with occasional bridges to allow cross-street traffic.
The first Grand Central Terminal was finished in 1871, increasing traffic so
much that area property owners persuaded the railroad to cover the tracks.
"In a large-scale project north of 56th Street between 1873 and 1875, the
engineer Isaac C. Buckhout designed beam tunnels — in which iron beams span
the tracks directly above the rail traffic — for areas where the land was low.
Where the land was high enough, conventional masonry arch tunnels were built.
"The tracks south of 56th Street were covered over as part of the construction
of the new Grand Central Terminal, completed in 1913."
