On Monday, May 13th, and Tuesday, May 14th, in both directions:

Maintaining the Network on Track

To ensure everyone's safety, we conduct surveillance and maintenance on the track equipment along the 384 km of lines RERrer ligne Aand RERrer ligne Bthat we operate. Our maintenance agents walk the tracks, meticulously inspecting each piece of equipment and its components. Around twenty track equipment units are replaced each year as part of these operations.
