LAS VEGAS — The Boring Company is digging faster than ever. The tunneling firm said this week that one of its Prufrock boring machines set a new company speed record on the Nashville Music City Loop, carving out more tunnel in a single day than any of its previous bores.
The milestone is a concrete sign that the company's core technology is maturing just as its ambitions go national, and it arrives days after a fresh injection of capital gave the firm one of the largest war chests in infrastructure.
Faster Than Ever
Speed has always been Elon Musk's obsession at The Boring Company. Conventional tunneling can crawl along at a few feet per hour, and the company has staked its business on beating that pace by a wide margin to slash the cost of building underground transit. The new Nashville record moves it closer to a long-stated goal of digging faster than a snail can walk — a deliberately quirky benchmark that translates into real dollars saved per mile.
The record run came on the Music City Loop, where crews have been tunneling steadily beneath Nashville to connect the airport, downtown and major venues. Faster bores mean the network can open sooner and at lower cost, a formula the company hopes to repeat city by city.
A Machine That Keeps Improving
Prufrock is designed to tunnel continuously, launching directly from the surface without the large staging pits older machines require. Each generation has added power, better guidance and improved muck-handling, and the company continues to refine the cutterhead and conveyor systems that set the pace of a dig.
