China unveils the worlds largest tunnel boring machine for high speed

Published on June 04, 2026 | Translated from Spanish

China has unveiled the Jiaoping No.1 tunnel boring machine, considered the largest in the world for high-speed trains. Weighing 3,500 tons and with a diameter of 15 meters, this machine integrates artificial intelligence to excavate safely and efficiently underground. Its goal is to bore through mountains and rivers to shorten distances between cities, reducing travel times for citizens.

Artificial intelligence underground: how the Chinese giant operates 🚇

The Jiaoping No.1 is not just a steel monster; its AI system analyzes geological data in real time, adjusting excavation speed and pressure to prevent collapses. This allows it to traverse complex terrains without pauses, something that previously required months of manual studies. With a diameter of 15 meters, it can create tunnels for two train tracks simultaneously, doubling railway infrastructure capacity in mountainous areas.

Meanwhile, in the rest of the world, we're still using pick and shovel ⛏️

While China buries this 3,500-ton behemoth, in some countries they are still debating whether or not to put a coffee machine in the station. The Jiaoping No.1 advances at AI speed, without unions or coffee breaks to slow it down. But it's not all envy: at least, when the tunnel is ready, we'll be able to cross the mountain in 20 minutes instead of three hours. That is, as long as there isn't a drivers' strike.
