In a few clicks, you will be teleported to the underground construction site, in creating the tunnel for the future RER E line.
To excavate the tunnel, the machine is tailor-made to adapt to the conditions of the project. The EOLE tunnel boring machine is called Virginie! This project transforms mobility in Île-de-France : the RER E line becomes the most interconnected line in the region.
A tunnel under construction is a rare sight. The EOLE project uses an extraordinary machine, a mud pressure tunnel boring machine. This "factory-train" will perform several tasks simultaneously. The excavation, the evacuation of the rubble, and finally creating the structure of the tunnel.
