"To accomplish this, the Boring Company would need to develop tunnel boring machines that could dig incredibly quickly. To this end, the startup has designed Prufrock, an all-electric TBM that's designed to eventually be fast enough as an everyday garden snail. Among TBMs, such a speed would be revolutionary. The startup has taken a step towards this recently, when The Boring Company posted a photo of Prufrock-5 coming out of its Bastrop, Texas facility."
"The startup has taken a step towards this recently, when The Boring Company posted a photo of Prufrock-5 coming out of its Bastrop, Texas facility. "On a rainy day in Bastrop, Prufrock-5 has left the factory. Will begin tunneling by December 1. Hoping for a step function increase in speed," the Boring Company wrote. All Prufrocks are reused, usually with upgrades between launches. Prufrock-1 has now dug six tunnels.- The Boring Company (@boringcompany) November 25, 2025"
The Boring Company develops all-electric Prufrock tunnel boring machines intended to dig much faster than conventional TBMs. Prufrock-5 left the Bastrop, Texas factory and is slated to begin tunneling by December 1 with hopes for a major speed increase. All Prufrock units are retrieved and reused, typically receiving upgrades between projects; Prufrock-1 has already completed six tunnels. Conventional tunnel boring machines are often abandoned underground because retrieval is expensive and impractical, but Prufrock designs prioritize recovery and reuse to reduce waste and lower lifecycle costs.
