About Sydney's Super Tunnel
The documentary series, filmed over seven years, delves into the complexities of the Sydney Metro project, focusing on the tunnel construction, including under-harbor tunnelling, the use of large tunnel boring machines, and excavation work deep below the city. It also highlights the role of steam locomotives and other aspects of the project including rigorous testing of the automated driverless trains to ensure the safety and longevity for many years of public use.
