Stochastic Studies on EOLE East-West

trenolab completed a stochastic study to assess the robustness of the proposed timetable for the extension of RER E services to Mantes. This project focused on analyzing the operational performance of the expanded East-West rail corridor under various scenarios and potential disruptions. The study employed simulation modeling to evaluate how the proposed timetable would perform across the extended network. Our team analyzed passenger flows, capacity constraints, and system resilience to determine whether the planned service frequency and scheduling could maintain reliable operations throughout the EOLE East-West railway. The research examined multiple operational scenarios, including peak-hour demands, minor delays, and service disruptions to identify potential bottlenecks and performance issues. Results provided insights into the timetable’s ability to recover from delays and maintain service quality across the network. This analysis supported decision-making for the RER E extension project, offering evidence-based recommendations for timetable optimization and infrastructure planning to ensure robust service delivery for passengers traveling between central Paris and Mantes. This work built on a previous study completed by trenolab in 2018 in preparation for extension of the line from St Lazare to La Defense, which would become a new rail service across Paris. We used probabilistic simulation to optimise the integration of the new infrastructure and CBTC signalling system in the existing network in the north and the east of Paris.
