Hospitals in the US have used pneumatic tube systems for a very long time. Modern tube systems are quite advanced and probably break down less often than the track/trolley systems. Many medical complexes even use pneumatic tubes between buildings on the campus to move samples, test materials and other items around in a coordinated system. The chinks are just building minor improvements onto the White created technology that has served us well in many industries for over 100 years.
