Tunnel Boring

Apparently, you don’t need a windshield to drive through a rock wall.

Some 19 stories under the streets of Manhattan on Thursday, the driver of a 640-ton telescopic tunnel-boring machine stood in a tiny windowless metal cubicle before a pair of small computer screens and an array of buttons and gauges.

“No windshield? Don’t need one,” said the driver (or operator, as he prefers), Anthony Spinoso.

Over several months he has driven the machine 7,700 feet, from a spot deep under Second Avenue and 63rd Street, through the bedrock, to the depths beneath Grand Central Terminal, where the tunnel he has helped dig will someday bring Long Island Rail Road trains to the East Side of Manhattan.
