Cargo Sous Terrain (“cargo underground” in French) is a Swiss initiative to build a computer-controlled cargo delivery system that will move freight underground through a series of tunnels crisscrossing the country. The vehicles will travel continuously at about 19 MPH along these underground pathways.
This goals of Cargo Sous Terrain are to reduce the traffic congestion caused by package delivery trucks and increase the efficiency of parcel services. This $3.4 (USD) billion project was first proposed in 2016. Now it has received government approval to begin construction.
Given projections that package delivery demands will increase 37% from 2010 to 2040 in Switzerland, there’s definitely a market for alternatives to road transport for this sector. You can read more at IEEE Spectrum.
