This paper addresses the challenges of efficient coordination and safety assurance of moving block train platooning system. Conventional railway signaling method which relies on static block systems often fail to adapt to high frequency scenarios and thereby limiting the railway system's operational flexibility and scalability. The moving block signaling approach through communication-based train control (CBTC) technology has recently been proposed and viewed as a potential solution alternative to address such limitations. To enhance railway system opearational performance and safety, this paper proposes a control strategy combining sliding mode control (SMC) and event-triggered control (ETC) for a multi-agent system representation of train convoy operating under moving block signaling scheme. The proposed SMC is used to ensure robust tracking and coordination of the train convoy in the presence of inter-train communication loss, while ETC scheme is used to minimize communication and computation overhead in each train by updating the individual train's control actions only when deemed necessary. The proposed approach improves coordination, safety, and resource efficiency within complex, multi-agent train systems. Simulation results demonstrate the effectiveness of the combined control strategy in maintaining inter-train spacing even when data transmission loss/drop occur on several time instances.
