When relocating to Paris, mastering the public transport system is a vital step toward independence and integration. For many expats, understanding how to use the train network efficiently is not only a question of logistics but also a gateway to professional opportunities, cultural exploration, and daily peace of mind.
Whether you are commuting to work, taking children to school, or planning a weekend excursion beyond the city, this article will guide you step by step through using the train system in Paris, including how to obtain a railcard and make the most of available travel discounts.
Understanding the Rail Network in Paris
Paris boasts one of the most extensive transport systems in Europe. It includes:
Métro: Serves central Paris with high-frequency service
RER (Réseau Express Régional): Rapid trains connecting Paris with suburbs and major hubs such as Charles de Gaulle Airport, La Défense, and Versailles
Transilien: Regional trains operating across the Île-de-France region
TGV (Train à Grande Vitesse) and Intercités: High-speed and long-distance national services
If you live in a residential area just outside the city center, you are likely to rely on a combination of Métro lines, RER trains, and Transilien services, particularly for travel toward business districts or weekend destinations.
7 Steps to Using the Train System Effectively
1. Obtain a Navigo Pass
The Navigo pass is an essential tool for everyday travel in and around Paris.
What is it?
A personal, contactless card that allows unlimited travel on the Métro, RER, Transilien, buses, and trams.
How to get it
Visit a major Métro or RER station and request the Navigo Découverte. You will need to provide a passport-size photo and proof of identity. The card costs €5, and you can choose a weekly or monthly subscription.
For most residents, the monthly all-zones pass (€86.40 in 2025) offers the best value.

2. Understand the Fare Zones
The transport network in Île-de-France is divided into zones, numbered from 1 to 5. Most travel within Paris itself takes place in zones 1 and 2. However, common destinations such as Versailles, Roissy-Charles de Gaulle Airport, and Disneyland Paris are located in zones 4 or 5.
Fortunately, the monthly Navigo pass includes unlimited travel in all zones, making it ideal for both daily commutes and occasional excursions.
3. Purchase Single Tickets When Needed
If you are not yet ready to commit to a pass, you can use single-use Ticket t+ (€2.15). It is valid on the Métro, buses, trams, and RER within central Paris.
Tickets can be purchased at station kiosks or via the Bonjour RATP app.
It is important to retain your ticket until you exit the station, as ticket inspections are frequent.
4. Use Travel Apps for Efficiency
Two recommended apps for planning your journeys are:
Bonjour RATP: The official app with live schedules, elevator alerts, and route suggestions
Citymapper: Offers multiple route options including the fastest, least crowded, and stroller-accessible alternatives
5. Find the Right Platform and Train
At RER and Transilien stations, check the digital display boards carefully. Look for the line number or letter, final destination, and list of intermediate stops.
Note that some trains are indicated as “train court” (short train), so be sure to stand in the correct zone on the platform.
In major stations such as Gare Saint-Lazare, allow extra time to reach your platform, as the layout can be extensive.
6. Save on Long-Distance Travel with a Railcard
If you plan to explore France by train, the Carte Avantage is an excellent investment. It is designed for adults, families, or young travelers and provides a 30 percent discount on most TGV, Intercités, and TER routes.
Cost: €49 per year
How to apply: Available online via SNCF Connect
Additional benefits: Discounts often apply to accompanying children or companions
7. Practical Travel Tips
Trains depart on time, so it is recommended to arrive early, especially for regional servicesBook high-speed train tickets in advance, as prices tend to increase closer to the departure date
Weekend unlimited passes are available for travel within Île-de-France and are ideal for exploring nearby destinations
If you are traveling with a stroller or luggage, check app updates for elevator access and station accessibility
