Program to Destination Currently much of our nation's freight has to be sent to Classification {Hump} yards.  These yards separate a single train into its individual freight units and then move the units to several separate tracks, thus making up several new trains that are scheduled to go to another Classification yard or to a final destination.  This is very time consuming and causes costly delays in moving freight.  The BorderTransportationSystem eliminates some of this by having individual motorized freight carrying units that can be programmed to go from or to the system by computer and sensor control.
