FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 4 Scenarios • The following scenarios have been specified 0. Baseline simulation, no perturbations 1. One Iron Ore Train delayed at departure 2. Extra train added 3. Long distance freight train delayed 4. Speed restriction between stations 5. Point out of order at one location • Meetings not possible

FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 5 Output from simulations

• Hermes simulator output • The Matlab tool, developed by UoB – Uses log-files generated by Hermes – Calculates quantitative measures for specified key performance indicators (i.e. journey time, resilience, punctuality, energy consumption, resource usage....). – Calculates and presents time-distance graphs for qualitative evaluation of PMM re-planning.

Baseline Scenario Speed Restriction Speed Restriction:

Time (hours)

FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 11 Simulations

• Simulations performed – Baseline simulations, with original timetable, no perturbations, to validate the model – Simulations with perturbations for the different scenarios, no PMM • Scenario 1: One iron ore train delayed • Scenario 2: Speed restrictions between two stations – Simulations with perturbations for the different scenarios, with PMM • ROMA algorithms • RECIFE algorithms

FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 12 Conclusions

• The Hermes simulator can simulate the IOL, with some limitations. • The PMM algorithms can perform operational re-planning in the tested scenarios. • To be fully relevant for the IOL, additional requirements must be fulfilled. Some limitations today are: – Headways are sometimes too small – Unnecessary stops for meetings are not eliminated – Priorities between trains are not specified – The interactive connection to human control is not developed – The integration of the PMM into the HMI of the traffic controller is not developed

FP7 - ON-TIME Collaborative Project Borlänge, October 2014 Pag. 23 Final Conclusions

• Further evaluation of the simulations are needed • The quality of the RTTP generated by the PMM will be further evaluated • Additional elements must be included in the model and in the PMM, e.g.: – Different types of stops/meetings (fixed, dynamic..) – Priorities • Interactivity must be developed, together with HMI for the traffic controllers
