Does the RER go underground?

Yes, the RER (Réseau Express Régional) does go underground in certain sections. The RER is a rapid transit system in the Île-de-France region in France, which includes the city of Paris. It is known for its extensive network of both surface and underground lines that connect various parts of the region. While some sections of the RER run on surface-level tracks, a significant portion of the network passes through underground tunnels.

The underground sections of the RER provide several advantages. Firstly, they allow the trains to bypass traffic congestion and provide a quicker means of transportation, especially during peak hours. Additionally, going underground enables the RER to seamlessly integrate with the Paris Métro system, facilitating convenient transfers between the two networks. This integration enhances the overall efficiency and accessibility of public transportation in the region.
