Objective As the "brain" of urban rail transit operations, train dispatching and command systems expose limitations such as insufficient safety assurance, difficult collaborative decision-making, and inefficient resource allocation in networked operation environments. There is an urgent need to construct a digital dispatching and control system with perception, analysis, decision-making, execution, and learning capabilities, so as to enhance the operational resilience and service quality of urban rail transit.

Method First, the connotation of resilient operation is defined, and the enabling role of digital technologies is analyzed. Second, a four-layer progressive digital transformation path of "information–process–business–decision" is proposed. Third, a five-part key technical system covering risk perception, operation optimization, emergency decision-making, collaborative control, and simulation rehearsal is constructed. Finally, through a case study on safety control of maintenance and construction in operational line management, the digital application effects—such as precise planning of construction windows, real-time safety control of maintenance operations, and the accumulation of construction experience and knowledge—are verified.

Result & Conclusion Digital transformation enables dispatching and command systems to achieve a fundamental shift from "experience-driven" to "data-driven" operation, presenting the characteristics of comprehensive perception, intelligent analysis, scientific decision-making, and automated execution. The case study demonstrates that through the closed-loop system of "perception–analysis–decision-making–execution", the safety control level of train operations during maintenance and construction periods on operational lines can be effectively improved.
