An automated train dispatching system

The automated train dispatching system (ATDS) is a computerized fault tolerant train schedule tracking and status information system. It consists of thirty-eight DEC PC workstations interconnected by modems, thick and thin wire Ethernet and fiber optic cable to a central VAXft computer acting as a database server. Three DECserver 700s provide forty-eight ports to drive nine end of line printers and three hundred “Transit Information Display Sign” (TIDS) Displays. The ATDS will be used by dispatchers and tower operators to monitor and administer the movement of trains in their territory by providing an accurate, real time status of train location. The inner workings of the traditional paper intensive system used to “run the railroad” are examined. The problems common to this system are identified and their impact assessed. The functionality of the new system is described. The streamlined operations under the electronic system are explained together with a discussion of the problems encountered when implementing the new design. The impacts on not only railroad operations but other departments with respect to the introduction of new technology, new technology/work interface and organization structure are explored. Integration of the design into the overall modernization plans are explored and finally, the lessons learned in implementation of this project are listed
