Quick Facts

Free 2nd class transport since 29 February 2020

Central hub: Luxembourg station (Gare Centrale)

Network length: ~275 km

Almost fully electrified at 25 kV 50 Hz AC

CFL: Luxembourg’s National Railway Operator

CFL (Société Nationale des Chemins de Fer Luxembourgeois) is the national railway company of Luxembourg. Founded on 14 May 1946 after the merger of the historic Guillaume-Luxembourg and Prince-Henri railway companies, CFL is headquartered in Luxembourg City and remains the backbone of the country’s public transport system.

CFL operates most passenger trains using electric locomotives and electric multiple units (EMUs), including a fleet of modern double-decker trains. The main train types are Regional Express (RE) and RegionalBahn (RB), providing fast and frequent connections across the country. CFL runs a punctual schedule called ‘Horaire Cadencé’, ensuring at least one hourly train to most stations between 8 AM and 8 PM.

In recent years, CFL has carried approximately 31 million passengers annually, reflecting the growing popularity of rail travel in the country. The network operates on standard-gauge track with the majority of lines electrified at 25 kV 50 Hz AC, allowing for seamless cross-border operations with France’s rail system.

CFL’s main responsibilities include:

Operating all domestic passenger train services (RegionalBahn and Regional Express)
Running cross-border routes to France, Belgium, and Germany
Managing freight operations through its subsidiary CFL Cargo
Maintaining railway infrastructure, tracks, and signalling systems
Operating and managing all stations across the network
Coordinating CFL buses and integrating with tram and funicular services

The fleet consists primarily of modern electric multiple units (EMUs) and double-deck trains, with only a handful of diesel units remaining for non-electrified maintenance routes. CFL also operates many bus routes through CFL buses and coordinates closely with RGTR (Régime Général des Transports Routiers) to provide comprehensive coverage where rail doesn’t reach.

Types of Trains and Services in Luxembourg

Understanding the different train types operating in Luxembourg helps you choose the right service for your journey. While the country doesn’t operate domestic high speed train services, the network offers efficient regional connections with regular services throughout the day.

RegionalBahn (RB) Trains

Luxembourg RegionalBahn trains are the workhorses of the domestic network. These all-stops local services connect smaller towns and villages to major centres, making them ideal for short-distance travel and local commuting. RB trains typically call at every station along their route, so journey times are longer than express services but coverage is comprehensive.

No reservation is required for RegionalBahn trains—you simply board and take any available seat. These train services run frequently on main corridors, often every 15-30 minutes during peak hours.

Regional Express (RE) Trains

Regional Express trains offer faster connections with fewer intermediate stops. They’re perfect for travelling between major towns when you want to save time. Popular RE routes include:

Luxembourg – Esch-sur-Alzette
Luxembourg – Ettelbruck – Diekirch
Luxembourg – Wasserbillig (continuing to Trier in Germany)

Like RB services, RE trains require no reservations. The main difference is speed: by skipping smaller stations, RE trains achieve higher average speeds and shorter journey times.

International Connections

International trains connect Luxembourg to major cities across the Benelux region and beyond. These include:

TGV high-speed services to Paris
TER and intercity trains to Metz, Thionville, and Nancy in France
Regional and IC services to Brussels via Arlon
Cross-border trains to Trier, Koblenz, and Cologne in Germany

Train Type	Stops	Reservations	Best For
RegionalBahn (RB)	All stations	Not required	Local trips, village access
Regional Express (RE)	Major stations only	Not required	Faster regional travel
International (TGV, IC)	Selected stations	Often required	Cross-border journeys

Integrated Transport Modes

Trains connect seamlessly with other modes that form part of Luxembourg’s multimodal public transport network:

Luxembourg City tram: Connects the station to Kirchberg and other districts
Pfaffenthal–Kirchberg funicular: Links the new Pfaffenthal station to the EU institutions plateau
CFL and RGTR buses: Extend the network to areas without rail coverage

Tickets, Free Fares and Rail Passes

Luxembourg’s revolutionary approach to public transport means that most domestic journeys require no ticket at all. Here’s exactly what you need to know about fares, passes, and when you do need to pay.

Free Domestic Travel

Since 29 February 2020, all second class public transport within Luxembourg is completely free. This applies to:

All CFL train services in 2nd class
City buses operated by AVL in Luxembourg City
Regional buses operated by RGTR and other providers
The Luxembourg City tram
The Pfaffenthal–Kirchberg funicular

No ticket, pass, or registration is required. Simply board any domestic service and travel freely. This policy applies equally to residents, tourists, and cross-border visitors for journeys that start and end within Luxembourg’s borders.

What Still Requires Payment

Not everything is free. You’ll need tickets for:

1st class upgrades: Quieter coaches with more space
International journeys: Any travel beyond Luxembourg’s borders
Reserved services: TGV trains to Paris and other French destinations
Cross-border commuter passes: For regular travel from neighbouring countries

Purchasing 1st Class and International Tickets

For services that require payment, you have several options:

Ticket office: Available at Luxembourg station and other major stops like Esch-sur-Alzette and Belval-Université
Ticket machines: Self service machine terminals at most stations
CFL mobile app: Buy tickets and store them digitally
mTicket app: For RegioZone cross-border tickets
Online portals: CFL’s website and partner booking platforms

First class offers a quieter environment, more legroom, and is often less crowded during busy periods—worth considering for longer journeys or when you need to work.

Rail Passes: Interrail and Eurail

Popular European rail passes work on Luxembourg’s network with some considerations:

Eurail Benelux Pass: Covers train travel in Belgium, Netherlands, and Luxembourg
Interrail Pass / Global Pass: Includes Luxembourg in its coverage

For Global Pass holders and those with a country pass, remember that Luxembourg’s free transport policy means you don’t technically need to use a travel day for domestic 2nd class journeys. However, your valid pass is still required for:

International train segments crossing borders
1st class travel (requires a 1st class pass or upgrade)
Reservation required services like international trains TGV

Digital Tools for Ticketing

mTicket app: Purchase and store RegioZone tickets for cross-border travel
mKaart smartcard: Load monthly or annual passes for chargeable journeys

Major Stations and Facilities

Luxembourg’s main train station serves as the heart of the national rail network, but several other stations play important regional roles.

Luxembourg Gare Centrale

Luxembourg’s main train station (Gare Centrale) is located approximately 1.5 km south of the historic city centre. This grand station, built between 1907 and 1913, handles virtually all domestic and international services and serves as the primary interchange point for the entire network.

Cross-Border Commuting and the Greater Region

Luxembourg’s economy draws tens of thousands of workers from neighbouring countries every single day. This makes the cross-border rail network one of the busiest commuter systems in Europe relative to the country’s size.

Daily Commuter Flows

Workers travel daily by train from:

France: Thionville, Metz, Longwy, and the wider Lorraine region
Belgium: Arlon, Libramont, and the Belgian Luxembourg province
Germany: Trier and the Moselle valley

Peak morning trains from these neigbouring countries are often packed, with services from Thionville and Arlon particularly busy. Evening return services between 17:00-19:00 experience similar crowding.

RegioZone Tickets

Cross-border travel is organised through the RegioZone ticketing system. Important: Luxembourg’s free domestic transport policy does not extend beyond national borders. Once you cross into France, Belgium, or Germany, you need a valid ticket or pass.

Ticketing options for commuters include:
