The exploration of complex networks within transportation systems has become increasingly critical for understanding and improving infrastructure efficiency and resilience. This study investigates the topological properties of the Indian Railways Network using network science and graph theory. The primary objectives were to analyze the network's structural characteristics, identify critical nodes, and assess its overall efficiency and robustness. Data were collected from the Open Government Data (OGD) Platform India, focusing on the Indian Railways Network dataset. Gephi software was employed for data analysis, calculating key network metrics such as degree distribution, average path length, clustering coefficient, and betweenness centrality.The analysis revealed a predominantly sparse network with most stations having limited connections, indicating potential inefficiencies and bottlenecks. Key hubs with high betweenness centrality were identified, underscoring their critical role in maintaining network connectivity. The average path length of 12.47 and a network diameter of 31 highlighted the extensive reach but also pointed to challenges in ensuring efficient connectivity across all regions. A moderate clustering coefficient suggested some resilience through localized clusters, though many stations remained isolated.These findings have significant implications for transportation planning and policy development. Enhancing connectivity and investing in critical hubs could improve network efficiency and resilience, supporting economic growth and improving the quality of life for millions. This study fills a crucial gap in the literature by providing a comprehensive analysis of the Indian Railways Network, offering valuable insights for both academic research and practical applications.
