Paris, RER

How to use it

The RER crosses Paris to link the suburbs on opposite sides, so it makes fast connections from east to west and north to south in the Ile-de-France. There are now 5 RER lines, each with its own branch lines.

The entrances to the RER are identified by posts carrying a sign RER in white on a blue background.

To reach the platforms you must pass through the checkpoints. On the RER, your ticket is checked on the way in and on the way out. Each line is identified by it colour, number and directions.

Timetables

The RER runs 7 days a week from 4.45 a.m. to 1.30 a.m. Timetables are posted in the stations and on the platforms.
