Key takeaways
- Standard-gauge steam in the Doller valley – full vehicle size on a genuine former branch line.
- Cernay is the key: starting station, depot and workshop sit together there and can be reached by train.
- The valley course makes the difference from plain shuttle lines – curves and gradient are usable for photography.
- Volunteer association operation with all the consequences: few running days, changing traction, a winter break.
- Plan across the season and combine with Mulhouse or the Rhine floodplain, rather than picking a single day.

How to recognise Train Touristique Thur Doller
Does the train really belong to Train Touristique Thur Doller?
- Standard gauge with steam – full vehicle size, not a narrow-gauge railway
- Its own heritage station in Cernay – right next to the state station, but operationally separate
- Older-design coaches – historic passenger coaches, some with open end platforms
- A valley course with curves – the line follows the Doller, producing curves useful for photography
- Volunteer staff – footplate crew and train guards are association members
- Seasonal train formation – the number of coaches and the traction change with demand and availability
Strengths and weaknesses
What the company stands for
- Standard-gauge steam with a genuine route profile rather than a plain shuttle
- The valley course provides several usable viewpoints within short distances
- The starting point Cernay is connected to the state network – getting there without a car is possible
- Combines well with Mulhouse and the Rhine floodplain in one weekend
- Several round trips per operating day allow you to correct your approach after the first attempt
Where it falls short
- Only a few running days a year, mostly on Sundays
- Which locomotive is running is rarely announced in advance
- Parts of the line are overgrown and hard to see from outside
- When busy, the trains are full – shots from inside the train become difficult
- Reliable information on the fleet and the state of the line is hard to find
Updated: August 2026 – Between Cernay and Sentheim lie a few kilometres of track that the regular passenger service gave up on long ago. The Train Touristique Thur Doller runs them anyway – with steam, historic coaches and a crew who keep the operation going in their free time. For photographers this is one of the more rewarding addresses in southern Alsace, because the valley delivers curves.
Keep steam days on your calendar
Heritage railways run on few days. Log where you were, when, and what ran.
What became of an industrial branch line
The Doller valley was textile and timber country. The railway arrived in the 19th century because factories and sawmills needed a link to the main line at Cernay. After 1918 the administration changed, and with the founding of SNCF the line passed into the state network – and in the decades that followed, passenger services disappeared step by step.
What was left was a stretch of line with no job to do. That’s exactly where the opportunity for a heritage railway lies: it doesn’t need a connection to long-distance traffic, just a usable track, a base, and people to maintain it. The association built itself its own heritage station in Cernay, right next to the regular station but operationally separate from it.
What the type of operation means for your shot
At a heritage railway you rarely see the same vehicle twice in the same role. Which traction is hauling the train fundamentally changes the subject – and with it, where you should stand.
| Traction | What you hear and see | Best spot | Critical factor |
|---|---|---|---|
| Steam, uphill | sharp exhaust beats, visible steam plume | to the side, below the ramp | cool air for visible steam |
| Steam, downhill | quiet, little steam | close-up, detail shot | steam is often missing entirely |
| Diesel | steady engine note | exit of a curve | the subject quickly feels ordinary |
| Shunting | brakes, coupling noises | station area from outside | mind the barriers |
The consequence: the uphill run is the more interesting direction. If you can only photograph one working, take the direction with the gradient. For the technique of shooting slow trains, Shutter speed and panning shots is worth reading; for the steam plume itself, see How to photograph steam trains.
Cool days beat sunny days
Visible steam forms through condensation. On a warm summer afternoon the plume disappears before it can be photographed – on a cool morning in spring or autumn it hangs over the whole train. If you can choose between two running days, take the cooler one.
Timetable pattern and planning
Trains run in the summer half of the year on selected days, mostly Sundays. The usual pattern involves several round trips: departure from Cernay, run to Sentheim, a stop, return. Exact times change every season and are published only on the association’s website – so you won’t find them here.
Operating calendar first
The number of running days a year is in the tens, not the hundreds. Without a date from the calendar, travelling there is a gamble.
Take the train to Cernay
The station sits on the state network. That makes this operation unusually easy to reach for a heritage railway.
Ride the first round trip
From the coach you can see where roads and paths come up to the track and where the vegetation is too dense.
Make the uphill run your main subject
On the run up the valley the locomotive is working. Plan your best spot for this direction, not for the return trip.
Cernay at the end
After the last round trip, shunting moves and shutting down take place – often the calmest subjects of the day, seen from outside.
How fast is the steam train really?
Enter the values from the posted timetable – the default figures are only a guide.
The workhorses of the Doller valley
The association operates standard-gauge vehicles: medium-sized steam locomotives as the workhorses of seasonal services, plus diesel locomotives and two-axle shunting tractors for reserve and shunting duties. The passenger coaches are older-design vehicles, some with open end platforms – a feature that makes shots from the moving train possible in the first place.
We deliberately don’t give running numbers. At association-run railways, the boiler certificate decides which machine is in service, and these certificates expire independently of any timetable. Heavy boiler work is farmed out by heritage railways across Europe to specialist operations; the best-known address in the German-speaking world is the Dampflokwerk Meiningen.

Photographing in the Doller valley
A good day when …
- steam is running and the air stays cool
- at least two round trips are on the timetable
- you have a vehicle to overtake the train between two viewpoints
Check first
- whether a special run with a photo stop is taking place
- whether the train is fully booked – that practically rules out shots from the platform
- whether engineering works close off sections of the line
Don't
- use the track bed or bridges as a viewpoint
- enter private land in the valley to get a clear view
- approach staff during operation
The big advantage over the main network remains predictability: the train arrives at known times, and it comes back again. Special trains sometimes add organised photo stops, where the train halts for pictures or passes a spot several times. How to find such dates in the first place is covered in Finding special trains and special workings.
A heritage railway doesn't mean less danger
Steam trains have long braking distances and are quieter than you'd expect – especially running downhill. The track bed remains operational railway land, even where trains run on only a few days a year. Stay on public paths and keep your distance from level crossings.
The association carries it all
The TTDA is not a transport undertaking, but an association. Footplate crew, workshop, train guards, ticket sales and line maintenance are all down to members who give up their free time for it. That explains the shape of the offer: few running days, a winter break, changing train formation.
The same logic applies to practically every operation in the region – from the Chemin de Fer Touristique du Rhin in the Rhine floodplain to the Kandertalbahn on the Baden side. Anyone who understands that plans differently: not spontaneously, but around the operating calendar.
For visitors the association structure also has a pleasant side. The people running the train have usually restored it themselves too, and are happy to talk about it – as long as you don’t approach them in the middle of operations. After the last return trip, while things are being shut down, is generally a much better moment for that than just before departure.
Verdict
The Train Touristique Thur Doller is one of the more accessible heritage railways in Alsace: reachable by train, running on standard gauge, with a line that has enough profile to deliver several usable subjects in one day. That’s more than many shuttle lines offer.
The price for that is the limited number of running days. Anyone planning a trip to Upper Alsace should put the operating calendar first and keep the Cité du Train in mind as a weatherproof alternative.
Quick verdict
Standard-gauge steam in the Doller valley with a usable route profile and good connections via Cernay. Few running days, but one of the more photogenic operations in the region.

Summary
- The TTDA is the classic case of an association-run railway on a line the state railway has given up on.
- Photographically the valley line is richer than flat heritage railways, because gradient and curves make the locomotive work audibly and visibly.
- The limiting factor is the number of running days, not the quality of the line.
- With Cernay as a starting point reachable by train, this is one of the most accessible operations in Alsace.
Frequently asked questions
Where does the Train Touristique Thur Doller run?
Between Cernay and Sentheim in the Doller valley, in southern Alsace between the edge of the Vosges and the Rhine plain. The starting point is its own heritage station, Cernay-Saint-André, which sits next to the regular station. The line follows the course of the Doller river westward.
What gauge is the railway?
Standard gauge, 1435 mm. That sets the operation apart from the narrow-gauge railways of the Vosges such as the Abreschviller forest railway. The locomotives and coaches are full size, so in pictures they look like a train of the main network – just with steam in front.
How do I get there without a car?
Cernay sits on a line of the state network and can be reached by SNCF trains. That makes the TTDA one of the few heritage railways in the region that can be reached purely by public transport. It's a short walk from the station to the heritage station.
Does a steam locomotive always run?
Steam is the main attraction, but not a guarantee. Depending on certificates, weather and availability, diesel vehicles are also used, including shunting tractors of the type built as the Y 8000. Anyone wanting to photograph steam specifically should check before travelling.
How long does a trip take?
Well under an hour each way. Heritage trains run slowly, usually somewhere between 30 and 50 km/h – one of the reasons the same line can be photographed several times in one day. We don't give specific departure times here, because they're set anew each season.
When is the season?
In the summer half of the year, with a clear focus on Sundays and public holidays. Special trains for particular occasions run in between. A spontaneous visit on any given weekend is likely to come up empty – the operating calendar is the first step of any planning.
Is the association a railway operator?
No. Operation takes place on a line separated from regular traffic, not on the network of SNCF Réseau. Everything is carried by an association: footplate duty, workshop, ticket sales and track maintenance are all in the hands of volunteers who give up their free time for it.
What do I do if there's no running day?
Use an alternative. The Cité du Train in Mulhouse is open regardless of weather or season and lies a short distance away. As a second operation, the Chemin de Fer Touristique du Rhin in the Rhine floodplain is worth considering too, also running on standard gauge.
Where do I stand to take photos?
On publicly accessible paths along the valley – roads, farm tracks and the edges of villages. The track bed itself is off-limits, even though the train runs slowly. What distances apply is covered in Safe distance from the track. For light planning, Planning sun position at a photo spot helps.
What vehicles are in the fleet?
Operational are medium-sized steam locomotives, along with diesel locomotives for shunting and reserve duties, plus historic passenger coaches. We deliberately don't give individual running numbers: at association-run operations the available fleet changes with boiler certificates and workshop capacity, and an outdated number would be worse than an honest gap.

Where you will find Train Touristique Thur Doller
Spotting locations where you will regularly come across vehicles from this organisation – with viewpoints, the best light and coordinates.
Strasbourg Gare Centrale
Strasbourg is the only major French station where German and French traffic meet every day. On top of that there's an architecture found nowhere else: a historic station building completely enclosed in a glass shell.
Border stationBasel SBB
No other station in Europe brings three national rail systems together as tightly as Basel. Swiss long-distance trains, its own French station section, and just a few tram minutes away a station on Swiss soil operated by DB – plus the most important north-south freight hub on the Alpine route.

Chemin de Fer Touristique du Rhin
The Chemin de Fer Touristique du Rhin keeps a standard-gauge branch line alive in southern Alsace. Its starting point is Volgelsheim near Neuf-Brisach, run with steam and historic carriages – carried by an association whose members look after the locomotive, workshop and track themselves.
Heritage railwayCité du Train
The Cité du Train in Mulhouse is France's central railway collection. It holds vehicles that exist nowhere else – from early steam locomotives to record-breaking electric traction. A museum with a collection, not an operation with a timetable.
Heritage railwayTrain touristique d'Abreschviller
The forest railway at Abreschviller runs on 700 millimetres – a gauge you rarely come across. A timber line in the Vosges woods has become a tourist railway that runs open carriages through a narrow valley. For photographers the forest is both a blessing and a problem.
Heritage railwayKandertalbahn
The Kandertalbahn links the Rhine plain at Haltingen with the small town of Kandern – standard gauge, with steam, on operating days in season. In Markgräflerland it has long been known simply as the “Chanderli”, and it lies so close to Basel that a railway day can be planned across two countries.
