Abstract：Research purposes: RBC is the core ground subsystem of the CTCS -3 train control system. With speeding up the construction of the passengerdedicated linewithCTCS -3 train control system, it isnecessary to do the research on the RBC control ability and its arrangementprinciple.
Research conclusions:Based on the description of the RBC system 's characteristics and components, analyses of the controlled objects and controlled range of RBC and the processing time, and discussion on the corresponding sectors related to RBC system controlability, the restrictedmodel for individualRBC controlability isgiven. By referencing the technical indexes stipulated in relative code forRBC system, the RBC arrangementprinciple and formula are presented,which can provide the reference to the similarengineeringworks.
