Effective security surveillance is crucial in the railway sector to prevent security incidents, including vandalism, trespassing, and sabotage. This paper discusses the challenges of maintaining seamless surveillance over extensive railway infrastructure, considering both technological advances and the growing risks posed by terrorist attacks. Based on previous research, this paper discusses the limitations of current surveillance methods, particularly in managing information overload and false alarms that result from integrating multiple sensor technologies. To address these issues, we propose a new fusion model that utilises probabilistic occupancy maps (POMs) and Bayesian fusion techniques. The fusion model is evaluated on a comprehensive data set comprising three use cases with a total of eight real life critical scenarios. We show that with this model the detection accuracy can be increased while simultaneously reducing the false alarms in railway security surveillance systems. This way our approach aims to enhance situational awareness and reduce false alarms, thereby improving the effectiveness of railway security measures.
