Switzerland may build an underground logistics system in tunnels using only renewable energy

IN Switzerland, an ambitious proposal could see the construction of an expansive underground network through which self-driving pods would transport freight across the country.

The new type of underground freight infrastructure would be complementary to the Swiss road and rail network, and relieve it at critical points.

Cargo Sous Terrain (CST) claims the project will reduce heavy traffic from Swiss roads by up to 40%, and because it will use only renewable energy, it will emit

80% less carbon dioxide per ton of cargo than transporting freight by road today.

The providers claim to establish a complete, automated, flexible and durable underground cargo system which allows the transport of pallets and crates for packages, individual items, break bulk cargo and bulk goods, as well as their storage.

If built, the whole cargo tunnel network would stretch around 500 km with the tunnels 40 to 80 metres below ground.
