How to Ride the RER
Enter the Station
Tap your Navigo card on the purple reader or insert your paper ticket. Wait for the green light and retrieve your ticket before passing through the turnstile.
Find Your Platform
Follow signs for your RER line. Check the overhead display panel on the platform - lit squares show which stations the next train will stop at.
Open the Doors
RER doors do NOT open automatically. Press the button or lift the handle near the door to open it. Don't wait for it to open on its own!
Ride & Monitor Stops
Watch the line map above the doors or listen for station announcements. Some RER trains skip stations, so verify your stop is lit on the platform panel.
Exit the Station
Keep your ticket until you exit! RER stations require ticket validation to leave. Insert your ticket or tap your card at the exit turnstile.
