Why Britain Is Building a £100B Railway That Only Goes Halfway

How did Britain engineer a £100 billion high-speed railway that became the world's most expensive? Welcome to NEXTGEN MANUFACTURING. In this documentary, we go inside the extreme engineering and brutal logistics of HS2—a megaproject designed to connect London and Birmingham at 360 km/h. Plagued by budget overruns, political controversy, and archaeological discoveries, HS2 became a national disaster. Yet, beneath the headlines, a truly extraordinary civil engineering feat is taking shape. In this technical deep-dive, we analyze: The £100B Problem: Why Britain’s HS2 costs £416 million per mile. TBM Operations: How 2,000-tonne machines bore 10-mile tunnels under London. Colne Valley Viaduct: Engineering Britain’s longest railway bridge over lakes and motorways. Slab Track Technology: Building 360 km/h precision track for 120 years of service.
