The show kicks off with a dynamic taster of what the series has in store - namely the inside story of a crack team building a trailblazing, fully-automated metro system costing $50 billion.

Action Stations

We check in on our engineers encountering all manner of issues tunnelling through a minefield of existing infrastructure - skyscraper footings and basements, sewers, a graveyard, and rail tunnels.

What Lies Beneath

Another super challenge looms, perhaps the greatest of the entire project - digging two tunnels beneath Sydney Harbour.

Digging Deep

We follow architect Ross de la Motte, seeing that his vision for the stations has finally come to light. He has gone to great lengths to design stations that benefit from natural light and airflow.

Fast Tracked

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.
