Companies compete to create the fastest high-speed rail for your luggage

Daifuku Co. is the name of a Japanese "material handling" company that acquired two of its competitors in the past five years...and has devised the high-speed BTS (Baggage Tray System), which whisks luggage along at 600 meters per minute.

True to the name of the system, each piece of luggage resides in its own tray like a passenger on an amusement park ride. Each tray has its own RFID tag, allowing individual pieces to be quickly sorted "with virtually 100% reliability," the company says.

Daifuku isn't leading the way, but playing catch-up: Siemens developed such a system as early as 2006—a year before Daifuku acquired the JWB Co.—and has implemented it in South Korea's Seoul-area Incheon Airport, as well as in Spain's Madrid-Barajas.
