Part 4/9:
To create the new rail network, the project utilizes advanced tunneling methods pioneered by historic innovators. For instance, engineers have drawn inspiration from the Romans’ ancient coffer dam construction technique, which allows for the creation of stable structures in water. By employing today's versions of this technique, they constructed a station deep in the River Thames, under challenging conditions and alongside high-profile financial institutions.
Engineers also adopted modern, silent piling technologies to avoid disturbing the surroundings while constructing critical structural elements, showcasing how old ideas can evolve into new solutions.
