A number of large cities had extensive networks of pneumatic tubes and underground rail runnels for delivery. They fell out of use with the rise of cars, but the idea that deliveries go via vehicles on streets is far from a given.
- reaperducer 8y agoCoincidentally, Chicago has a disused network of underground delivery rail tunnels. They were widely forgotten until a pile was driven into one beneath the Chicago River and the river flooded many of the buildings in the downtown's Loop district.† Today a few are still used, though not for deliveries. Mostly for running fiber optic networks, and the Palmer House Hotel uses its section to raise mushrooms for its restaurant.‡ † https://en.wikipedia.org/wiki/Chicago_flood https://en.wikipedia.org/wiki/Chicago_flood ‡ https://www.dnainfo.com/chicago/20140618/loop/palmer-house-hilton-grows-mushrooms-old-tunnel-under-loop/ https://www.dnainfo.com/chicago/20140618/loop/palmer-house-h...
