RECOMMENDED PREREQUISITES FOR REPLACING CABS WITH SOR IN THE BART TRAIN CONTROL SYSTEM

An evaluation is given of the prerequisites for the replacement of the train control system for the Bay Area Rapid Transit (BART). The Sequential Occupancy Release System (SOR) has several potential advantages for long-range improvement over the currently used Computer Augmented Backup System (CABS): (1) better resolution capability--train occupancy information for more than 1500 individual blocks can be displayed; and (2) better maintenance capability--an automatic problem reporting system is compatible with the SOR system. SOR will, however, have some shortcomings with respect to certain operational problems, failsafe reliability, and failure detection. It is concluded that SOR, used as a backup system, can provide a level of safety comparable to that provided by CABS.
