Strategic audit of SNCF-Transilien operations

Ahead of negotiating its contract with the Île-de-France transport organising authority (STIF), SNCF’s Transilien Directorate sought a shared assessment of the key balances across the SNCF – Transilien network, together with the possible trajectories for passenger service quality in the short and medium term (2020–2025 horizon).

The analyses, entrusted to EPFL and IMDM, examined the effects of renewal efforts on network ageing and on performance as perceived by passengers, as well as the suitability of operating methods for high traffic volumes. The study showed that passengers would only perceive the renewal effort after around ten years, and that this effort alone would not be enough to guarantee improved network performance.
