A fake townhouse in Brooklyn Heights hides a subway ventilator
If you’ve been paying attention you might already know this, but those blacked-out windows hide the fact that there’s no house behind the façade of 58 Joralemon St in Brooklyn Heights. Instead, there’s a subway ventilator and an emergency exit, stuck there when the original townhouse was gutted in the first half of the 20th century.
There's a mysterious A/C/E lower level track at Port Authority that was never actually used
NYC has a bunch of abandoned subway stations, like the old Worth St and 18th St stops, plus abandoned platforms in otherwise functioning stations (Hoyt-Schermerhorn, for one). But the abandoned track under the 42nd St Port Authority station might be the strangest of them all. It’s unclear why it was built in the first place, since it never operated as part of the IRT or IND systems. It was apparently used for the special Aqueduct Racetrack train, which ran express to the racetrack from 1959-1981, which actually sounds pretty awesome..
