They’ve been working on the rail weigh The scale company Mettler Toledo said it has developed a new system that allows the weighing of coupled railroad cars while a train is in motion, eliminating the costs and hazards of uncoupling and positioning each car for weighing.
   The Columbus, Ohio-based company said that by integrating a dynamic weighing controller with a dynamic rail scale, entire trains can be weighed as they cross the scale at speeds up to 6 mph. Individual rail car weights are obtained without uncoupling cars, and train total weights are automatically calculated. Rail car identification information from an RFID tag is integrated into the weighing record. The controller stores and prints weight information for any length train, even those exceeding several hundred cars, and provides data storage for hundreds of trains.
