SNCF Réseau is undertaking various modernization projects across the French railway network, resulting in localized service interruptions and community impacts.

In late September, modernization work on the Dijon-Paris line in Plombières-lès-Dijon involved track reconstruction and switch renewal. This period also saw disruptions caused by a fire near the network, which forced passengers to walk along tracks to reach a transport point.

By late October, broader modernization efforts were reported. On the Bordeaux-Toulouse line, upcoming works to prepare for high-speed rail will necessitate total traffic stoppages between November and December. Additionally, track renewal on the Paris-Orléans line in Savigny-sur-Orge, though primarily scheduled at night to maintain daytime traffic, has led to local complaints regarding noise pollution and parking issues.
