Cargo sous terrain is a collaborative effort of multiple Swiss firms engaged across transport, logistics, retail, telecom, and energy sectors. The concept uses the principle of automatic conveyor systems to connect production and logistics hubs with urban centers.

Hubs in the system are equipped with vertical lifts that can load and unload goods in an automated fashion into the transportation system that is completely underground. Moving the goods in the transportation system are vehicles powered by electric drives that move at a constant speed of 18 mph (30 kph) and carry goods in pallets or modified containers…

However, the project that will commence on August 1st only includes a short phase of 43 miles (70 km) between the cities of Härkingen-Niederbipp and Zurich, which will include 10 connection hubs and is expected to be completed by 2031. The estimated project cost for this pilot phase is now $3 billion dollars with the cost of the entire project ballooning to $35 billion.
