This year marks the 100th anniversary of the opening of Grand Central Terminal.
But the train station is brand-new according to this vintage postcard, which offers a fascinating glimpse into the many layers underneath the street-level station.
It’s hard to read the faded print. But just below the street is the triborough train concourse, followed by the suburban train concourse, which is on the same level as the West Side, Bronx, and Brooklyn subway concourse.
Below that is the McAdoo Tube to New Jersey, then the Belmont Tube to Long Island. When did trains from Grand Central stop going to Jersey and Long Island?
