A bit of bore.
Queens, NY. February 9, 2012.
Installing the drill head for a Queens subway tunnel shaft. Slow, claustrophobic, exhausting work, the drill’s innards are a cramped hive of grease, hose, and steel. And it’s not a job for the impatient; once in place, the drills often chew earth only at a quarter inch per minute.

Very cool stuff.
