To conduct the track and ballast replacement work while minimising passenger inconvenience, RATP plans to completely close the stations affected by the construction work each summer until 2021 as follows:
- Between 2015 and 2018, traffic will be totally halted on certain sections during 4-week periods, 24 hours a day, 7 days a week. During these periods, service will remain fully operational on either side of the sections closed for construction.
- Between 2019 and 2021, traffic will be totally halted at night and week-ends, during 7-9 week periods. Service will be provided on the most heavily used links between Paris and the suburbs during morning and evening rush hours..
