FAQ

Train tickets include a round trip between Mariembourg and Treignes. Museum admission is not included, but can be purchased separately. For a combined “Train+Museum” ticket, the ticket includes, as the name suggests, the round trip between Mariembourg and Treignes, as well as free admission to the museum.

Reservations guarantee your place on board. Depending on the number of passengers and the health protocols to be respected, trains fill up very quickly, several days in advance. By coming without a reservation, you accept the risk of not being able to board.

You can book and pick up your tickets online at www.cfv3v.eu. This guarantees access to our facilities. Without a reservation, we cannot guarantee full access to our attractions, depending on the number of visitors and the sanitary protocol in force.
On site, the Welcome Centers are equipped with a ticket office where you can buy your tickets for the trains at Mariembourg and for the museum at Treignes.

The basic fare offers a round trip between Mariembourg and Treignes, passing through Nismes, Olloy-sur-Viroin and Vierves. You’ll discover the 3 Valleys region along waterways, forests and meadows.
Not all our trains are steam-powered, so check the timetable (color code).

A one-way trip by steam train takes 40 minutes, and 30 minutes by railcar. For the return trip and a visit to the museum in Treignes, allow around 2h30.

The timetables are available in 3 color codes and determine the day’s schedules and traction modes. The yellow timetable is dedicated to a day entirely reserved for railcars. The green day has 2 railcar departures and 1 steam locomotive. The blue schedule is dedicated to 2 steam locomotive departures and 1 diesel locomotive departure. Please note that when a steam train is scheduled, the main departure is at 2.20pm. For morning or late afternoon departures, please refer to the color code.

No, we also run railcars and diesel locomotives. Please refer to the color code of the day to find out the type of traction and departure time.
What are the differences between a steam train, a diesel train and a railcar?
A steam train is pulled by a steam locomotive. The train consists of at least one locomotive and passenger carriages. A railcar is a self-propelled rail vehicle, so there is no locomotive. Passengers travel in the same vehicle as the driver.
When the advertised traction mode is a diesel locomotive, it is the same composition as the steam train. Only the locomotive is different, using diesel power to pull the train.

The times given are those of the train’s departure. We recommend arriving 1 hour early, so that you can visit the ticket office, the souvenir store or have a drink.
As the Mariembourg site is open to the public, you can also wander around the rotunda (locomotive shed), discover the water pump, the coal store and the exterior of the water tower.

Sections are journeys between 2 stations, but not the whole way.
For example, Mariembourg-Nismes or Nismes-Olloy.

Our steam trains also have a carriage accessible to people with reduced mobility. Book the PMR carriage by contacting us several days before your arrival, so that we can give you the best possible welcome. Unfortunately, the Nismes and Vierves stops are not accessible to people with reduced mobility.

We can transport your bike on steam trains at no extra charge, subject to availability.
!! Unfortunately, the Nismes and Vierves stops cannot be served.

Generally, yes. Depending on the timetable, it is possible to take a diesel railcar/train on the outward journey and a steam train on the return, or vice versa. Please consult our timetables on our home page. If in doubt, don’t hesitate to contact us by email: secretariat@cfv3v.eu or by telephone on 060/31.24.40.

Yes, under your own responsibility. We decline all responsibility in case of incident or accident. We draw your attention to the environment around and inside the train, which may bring unusual noises, smells and sensations for your dog, and modify his behavior.

Eating is not permitted on board the train (except for the train-restaurant formula – check out the season’s events). Light meals (pasta, croque-monsieur, lasagne, cheese sandwiches) are available at the Treignes museum, the terminus station. In Mariembourg, some snacks are available à la carte. Picnics are permitted, subject to consumption on site.

The village of Treignes stretches over several kilometers. Depending on your wishes and your walking habits, it may be possible to combine your trip with another visit. For more information on Treignes museums, visit www.treignes.info

Some vouchers or discount codes may not be taken into account when booking online. In that case, give us a call and we’ll take your reservation over the phone. Don’t forget to present your discount at the ticket office. Without it, the normal rate will apply.

Apart from the letter M, which changes, the acronym CFV3V stands for Chemin de Fer à Vapeur des 3 Vallées, the association that operates railroad line 132 between Mariembourg and Treignes, in other words, steam and diesel trains.

The acronym MCFV3V stands for Musée du Chemin de Fer à Vapeur des 3 Vallées. The museum’s management association looks after the museum and the exhibition of locomotives, carriages, vans and other railway and industrial equipment on display at Treignes.

The 2 associations are quite distinct from each other, even if on a day-to-day basis they collaborate and work together to safeguard our railway heritage.

This depends on the sanitary protocol in force on the day of your visit. As explained elsewhere, it is advisable to book online. If you have any questions, please call us on +32 (0)60 31 24 40.

Whether at the museum or on a train journey, we offer group rates for groups of 20 or more paying guests. If you would like to make a reservation for a group equal to or greater than this capacity, please call us on 060/31.24.40 or contact us by e-mail: secretariat@cfv3v.eu.
