This project focused on developing a web-based application for the analysis of DC railway networks. The system was designed as an integrated simulation framework incorporating various elements such as a server, databases, and visual analytic tools, all built using open-source software. The application enables users to design DC railway feeding systems and analyze the impact of different components, including vehicles, substations, overhead feeding systems, and both on-board and wayside energy storage systems. While initially developed for DC railway networks, the framework’s flexible structure and tools can be adapted for other railway and electrical transportation systems, making it a versatile solution for transport infrastructure analysis.
