Line 3bis: the first summer construction project on the RATP network
Our teams take you behind the scenes of summer construction projects on the RATP network! For this first episode, head to line 3bis.
From 29 April to 9 May 2023, our RATP operational staff worked tirelessly to replace three sets of track equipment. With a focus on safety, foresight and timing, these expert teams work relentlessly to meet customer needs and, more broadly, to improve mobility for all users of the line.
Every year, work carried out to maintain and modernise this historic network improves travel for 12 million passengers in the Paris region.
