ANMR project: Catenary reinforcement to modernise RER D
In response to the constant increase in passenger numbers on the Ile-de-France lines, SNCF Réseau has undertaken to modernise the RER D infrastructure to accommodate new, higher-capacity trains. This initiative includes significant adaptations, in particular the reinforcement of catenaries and power substations on the Paris-Melun line.
The work is being carried out by ETF’s catenary teams with the support of ETF Services, which is responsible for APLAM and APS9 rail safety services. The project is divided into three sections. The first, between Paris Gare de Lyon and Combs-la-Ville, was completed between 2020 and 2022. The second, between Grigny and Corbeil-Essonnes, ran from September 2021 to December 2023, involving 80 ETF employees and 60 weeks of night work. This segment also included the construction of 300 foundations, the installation of 450 fittings and the unwinding of 42 km of Feeder.
The last section, from Combs to Melun, began in January 2024 and will continue until 2027. The aim of this phase is to finalise the adaptation of the infrastructure for the new trains, by continuing efforts to reinforce the catenaries and power substations.
ETF’s catenary teams were able to win each section thanks to the quality of their bids and the work they delivered. Their ability to meet deadlines guarantees minimal disruption for users. This modernisation will enable the RER D to accommodate larger trains and respond effectively to the growing need for mobility in the Île-de-France region, offering an improved service to millions of passengers every day.
