The station welcomes some 100 million travelers on all rail lines and record 300 million travelers each year when including all public transport.
SNCF Réseau, the agency managing railtracks, will replace the signal box in the underground station as well as the one in the approach area with state-of-the-art computerized systems. This operation will also help prepare for future upgrades to the north–south rail corridor in the Île-de-France region.
During the same weekend, SNCF Réseau will also commission new access tracks to a future maintenance center and perform preparatory technical work for a large-scale project to replace switches and tracks in 2027.
An exceptional number of workers
Nearly 500 workers will be mobilized around the clock for 72 hours. The scale of this effort reflects the complexity of the equipment being installed: a total of 400 km (about 250 miles) of cables were laid during preparatory phases, enabling the creation and testing of 15,000 system connections over the weekend.
The main work phase will run from the evening of Thursday, April 30 through midday Sunday, May 3. During this period, transport operators will provide adjusted service on certain lines.
A complete stop at Paris Gare de Lyon for three days
From Friday, May 1 through Sunday, May 3 at 2:00 p.m., no trains will arrive at or depart from Gare de Lyon. For long-distance services, a gradual relocation to other stations will begin Thursday evening at 8:30 p.m. and become complete on Friday.
TGV services, including international routes to Switzerland, Italy, and Spain, will be redirected to other Paris and regional stations.
Regional services will also be affected. RER D will be partially suspended within Paris, and Transilien Line R will be heavily disrupted, with terminals moved outside the capital. Alternatives will be available, though travel times may be longer. Gare de Lyon itself will remain open to the public throughout the weekend, including its shops, and no disruptions are expected on the metro network.
Here are the details for all the lines transferred from Paris Gare de Lyon to other stations in and outside Paris during these 3 days.
