Ah the Big Apple
Quite typical for the Big Apple just not on such a scale. Having been a steam troglodyte as a kid you see stuff like this or the potential for this. Occasionally when the tunnel floods the insulation saturates heat loss goes way up and starts condensing at a rate greater then the trapping can handle or it cruds up and trap fails shut. Then the water slug is accelerated to a turn usually an elevation change and the pipe or fittings separate.Depending on location back then you could have 180 - 200 psig steam in the east 40's.Between the gas leaks Con Ed's powerlines in the tunnels Manholes would pop on a regular schedule. The standing joke was that visitors could keep any manhole cover they could catch.0
