2nd avenue subway is muuuuch deeper than most of the 100 year old stations in manhattan, for just this very reason. And also because no one would stand for cut

  "Cut and cover" being what exactly? Trenching down from the surface and then filling in above the tracks? Hardly seems practical beyond a fairly shallow depth.

    Yet with the exception of London, that's how most of the world's pre-existing subways were built. London is a bit of an outlier as it was very highly developed even in the late 19th century and there was a great fear of damaging existing "tall" buildings. Although even there a large amount of cut and cover tunneling exists.
