A €2.1 billion 15 year plan has been approved for the modernisation of the group of Transilien suburban lines east of Paris together with improvements to the eastern section of RER Line E. This has been approved by the board of Île-de-France transport authority Stif.
A number of short, medium and long-term measures have been proposed to cope with rising passenger numbers which increased by 3.8% per year between 2010 and 2015 on Transilien Line P services from Paris Est and 2.4% per year between 2008 and 2012 on RER Line E.
In 2015 SNCF Network invested €15m a year in infrastructure enhancements on the eastern section of Line E and €40m on Line P. The plan approved by Stif envisages increasing investment to €60-65m a year across both lines, an increase of nearly 25%.
Electrification of the Longueville – Provins branch is due to begin next month and Stif envisages Paris Est – Provins be operated by a fleet of 18-21 Francillien EMUs by 2021, offering up to 200 additional seats per train.
Additional peak trains are also proposed on the Longueville (from 2018) and Chateau-Thierry. The plan also calls for the extension of RER Line E (south branch) services currently terminating at Villiers-sur-Marne to Roissy-en-Brie. Several measures are currently being evaluated to facilitate this extension, including the acquisition of additional rolling stock and the construction of an additional track between Villiers-sur-Marne and Emerainville.
Power supplies will be upgraded on the lines to Meaux and Château-Thierry. The older trains on the Paris Est – Trilport – La Ferté-Milon line will be replaced by AGC DMUs. New studies will be carried out to provide up-to-date costings for electrification of the Trilport – La Ferté-Milon section, which is likely to be implemented in 2025-2030.
