I recently scouted a great parking garage on 44th between Vanderbilt and Madison. It’s right next to Grand Central Station, and was built quite a while ago.
It shares some iconic Grand Central-esque features, from the brick in the walls to the zig-zagging arched roof over the ramp.
While shooting pictures, I noticed something odd on the parking lane closest to Grand Central: cab stop signs engraved in the floor every eight feet or so. This is very weird, considering this space is usually three lanes deep with parked cars (I took these pics at night after the garage had closed).
According to the parking guys, back in the day, this garage was actually a main exit for Grand Central. Cabs would line up to drop-off/pick-up customers here.
The path from Grand Central to the parking garage still exists, right next to the Pylones store and the Transit Museum on the western end. It’s not marked, and feels like an area that’s off limits to the public, but it’s open for anyone who knows about it.
I’m curious if there was a grander exit when this was more active.
