Does Manhattan suffer from heat soak in the underground?

I know in London, the Underground has generated so much heat over so many years, it no longer cools in Summer but instead retains heat overnight meaning it's sweltering even deep underground in many stations for much of the year. https://www.ianvisits.co.uk/articles/cooling-the-tube-engine...

It's always somewhat surprising to me that given a bit of time, a seemingly inexhaustible resource like heat capacity of the ground or ground water can actually be depleted once we put our minds to using it.

Or the ability of the atmosphere to just "disappear" all that ICE exhaust.

The NYC subway is pretty much all cut-and-cover and doesn't have many tunnelled parts like the deep-level Tube lines.
