PARIS ST LAZARE, FRANCE.

ANALYSIS OF REAL OPERATIONS, PROPOSAL AND SIMULATION OF MEASURES TO INCREASE PUNCTUALITY. 

Paris Saint Lazare is not only one of the most famous stations in the world thanks to Monet’s paintings, but also the busiest terminal station in Paris. With over 1200 train on 5 lines entering a terminal station with 27 tracks operations in the station and on the lines are extremely congested in the peak hours.

Our team was asked to identify the critical points in current operations and suggest a set of operational or infrastructure improvements that would allow increasing punctuality.

Using the TRENOAnalysis tool, we analysed actaul delays, identifying the critical trains and weaknesses in the timetable. To ensure the correct understanding of these phenomena, we reproduced them simulating operations on the entire network using the reals delays as input.

Once this model was quality-proof, based on the results of the analysis, together with the operator SNCF Transilien identified a list of possible improvements to the processes, the timetable and the infrastructure and used the model to test their impact on reliability of operations.

✓ Large-scale analysis of operations
✓ Stochastic simulation of the entire network
✓ Effects on punctuality of a set of improvements
