Steam shovels could even use diesel. Steam shovels dug by pushing the bucket out. Backhoes dug by pulling the bucket back in. WTC was dug out using steam shovels (and dynamite).

Post was intentionallysketchy until reading the NY Time article. Back then, it was so deep that a pipe on stilts was actually a subway tunnel - the unique subway called PATH.

The remains of another tunnel was also observed in ground zero. Not sure. But could have been the original subway tunnel that moved trains using fans.
