Luxembourg–Brussels by InterCity

Belgian InterCity trains leave Luxembourg roughly every hour and call at Arlon, Namur and four Brussels stations: Brussels-Luxembourg (by the European Parliament), Brussels-North, Brussels-Central (three minutes from the Grand-Place) and Brussels-Midi, where Eurostar and the high-speed trains leave. Most are direct; a few need an easy change at Arlon.

• Fixed price, any train that day: €21.30 in 2nd class, €37 in 1st. Under 26 or over 65: €12.80 / €22.60. The price is the same on the day — tickets cannot sell out.
• No reservation: sit where you like.
• No catering: bring food and drink. Power sockets are few — there are usually two per carriage on the single-deck trains.
• Book on the Belgian railways’ international site (b-europe.com) or Trainline; seniors’ fares only on b-europe.com.

Liège and the Ardennes

A second hourly InterCity runs north through the hills of Luxembourg and the Belgian Ardennes to Liège (Léck in Luxembourgish) — a pretty ride. From Liège, regional trains continue to Maastricht and the Netherlands; see Luxembourg to Amsterdam and the Netherlands.

Arlon, Bastogne and the border towns

The Belgian province next door is also called Luxembourg, and Arlon (Arel) is its capital. Cross-border buses — TEC lines from Bastogne, Florenville, Virton and Arlon, and RGTR lines to Arlon, Messancy and Bastogne — use the RegioZone fare: €3 for two hours, €5 for a day, €40 a month. Trains to Athus are free in second class. All of it is explained in Free public transport in Luxembourg.

Charleroi airport

Brussels South Charleroi airport serves many low-cost flights. The Flibco shuttle runs from P+R Bouillon in Luxembourg to the terminal in about two and a half hours — ten departures a day and fares from €20.50, according to its 2026 announcement. Compare it with other options in Airports near Luxembourg.

Language: what is spoken where

Brussels is officially bilingual (French and Dutch), Wallonia is French-speaking, Flanders Dutch-speaking, and the east cantons German-speaking. The Belgian province of Luxembourg is French-speaking, though Luxembourgish is still heard around Arlon.

Luxembourgish for the trip

A few sentences from the official dictionary, each with its native recording — the kind you will use on the platform and on the bus. More in Luxembourgish on the bus and the train.

Also useful on the road, each with native audio: good morning, good evening, yes and no, nice to meet you — and the words for food, times and dates, the weather and money.

The verbs you need on any journey: fueren (to go by vehicle), huelen (to take), ukommen (to arrive), waarden (to wait), bezuelen (to pay) and reesen (to travel).
