The EMR Robin Hood Line (RHL) is a single-track line between Nottingham and Worksop (UK) with trains running in each direction at half-hourly intervals. Due to the infrastructure constraints the RHL is sensitive to late running trains since their delay propagates also to trains running in the opposite direction.
EMR tasked trenolab to enhance the resilience of service recovery policies for the May 2021 timetable one the RHL line. After constructing the actual infrastructure model and calibrating the microscopic model we developed two different studies:
- A stochastic simulation based on real data variations.
- A deterministic sensitivity study to late runnings consisting of 780 delay scenarios.
Later in 2022, using the same methodology, trenolab was tasked to analyse the timetable for May 2022 (with service recovery after COVID-19) and provide comparison metrics.
