You’re building a railway under London. You need 83,000 prefabricated tunnel wall segments. Your factory is in Hartlepool, 250 miles (400km) north of Old Oak Common. If that seems like a rail freight job, you’d be correct, even if that means reinstating a disused rail connection at the County Durham port. All that makes sense for the UK’s high-speed rail project, HS2, and it is rail freight to the fore once again, answering the mammoth lift task to support the biggest infrastructure project in Europe.
