Key takeaways
- "Bäderbahn" states the purpose: the line was built for traffic to the Baltic resorts.
- Narrow gauge is a closed system – vehicles cannot be swapped with the standard-gauge network.
- Steam operation is stock-based operation: water and coal help determine the running of the day.
- The street section makes this railway special – and demands particular care from everyone involved.
- Vehicle rosters and running days change – always check the current status before travelling.

How to recognise this operator
Is this really Mecklenburgische Bäderbahn Molli GmbH & Co KG?
- Noticeably narrower gauge than the standard-gauge network – vehicles look compact and low
- Steam locomotive at the head of the train with visible smoke and steam
- A section through the streets of Bad Doberan: track between the carriageway and the pavement
- Short passenger coaches in narrow-gauge dimensions rather than standard-gauge coaching stock
- Clearly audible operation: whistle, exhaust beats and braking sounds instead of an engine running
Updated: August 2026 – A steam locomotive running through a street between rows of houses, and a gauge noticeably narrower than anything on the standard-gauge network: the Molli seaside railway is one of Germany’s most distinctive railways. This page places it in context and uses it as an example to explain what steam operation means in practice – namely an operation that lives on stock: water, coal and time.

What is the Mecklenburg seaside railway Molli?
Mecklenburgische Bäderbahn Molli GmbH & Co KG operates a narrow-gauge railway with steam traction between Bad Doberan and the Baltic coast. The name element “Bäderbahn” states the original purpose: guests were meant to get from a connecting point on the main network to the seaside resorts.
Technically the railway is a closed system. The gauge of 900 millimetres is well below that of the standard-gauge network, and vehicles are not interchangeable with it. On top of that comes the feature that has made the railway known beyond the region: in Bad Doberan the line runs for a stretch through the street, directly between buildings and traffic.
Tourist operation does not mean heritage railway
Heritage railways preserve vehicles out of historical interest and run them on selected days. Tourist railways like this one also fulfil a transport function for visitors to the region. The line is fluid – what both have in common is that the service and vehicle roster fluctuate seasonally and therefore always need checking against the current status.
Recognition in the field
Judge the gauge
The distance between the rails is noticeably small. Best seen by comparison with a standard-gauge track or at a road crossing.
Determine the traction
Steam is unmistakable: smoke, white steam clouds, exhaust beats and the whistle. A diesel vehicle sounds and smells completely different.
Look at the coaches
Short, low passenger coaches in narrow-gauge dimensions – noticeably smaller than standard-gauge coaching stock.
Read the surroundings
Street, platform or open line: where the train is running determines which location is permissible and safe for you.
Water, coal, fire: what steam operation means in practice
A diesel vehicle refuels and runs. A steam locomotive, by contrast, works with supplies that are constantly consumed and replenished during operation – and with a fire that is lit hours before the first run. That shapes the daily routine more than any timetable. That this effort can be reduced with modern technology is shown by the oil-fired new-build engines of Dampflokomotiv- und Maschinenfabrik AG (DLM).
| Operating supply | What it is needed for | What that means in daily practice |
|---|---|---|
| Water | turns to steam in the boiler – the actual working substance | must be replenished en route at water cranes, fixed stops in the roster |
| Coal | generates the heat for raising steam | topped up at a coaling point, stock limits the range |
| Fire and boiler pressure | keep the locomotive ready for service | lighting up takes hours, pressure must be maintained throughout the day |
| Ash and clinker | residue of combustion | ashing out is part of every operating day, not the exception |
| Lubricants | the running gear and motion need constant care | oiling up at every stop, visible all around the locomotive |
The principle is the same for every steam locomotive, regardless of gauge: standard-gauge engines such as the Class 52 or the Class 41 work on the same basis, but carry much larger supplies. On narrow gauge, boilers, tenders and water tanks are smaller – so the resupply intervals are correspondingly shorter. For the major overhauls of boiler and motion, German steam operations regularly send their locomotives to the Meiningen Steam Locomotive Works.
Which locomotive is running today?
Community sightings show you which vehicles have most recently been reported.
Water crane, coaling, ashing out – the stages of the daily routine
Anyone who watches a steam operation for longer than a single train journey quickly notices: the most exciting moments lie between the runs. At the water crane the train stops, the swing arm is pulled across, and for a few minutes something happens that you will not see on any modern vehicle. At the coaling point supplies are topped up, and at the end of the day the ash is removed.
These processes are not a show, but work – and they almost always take place on operational railway land. That is the key point for you: observing, yes, but only from publicly accessible areas and without disrupting the work. Where an operator shows such processes as part of a guided tour, that is the only opportunity to get closer.
The sequence of the daily routine is also remarkably stable and can be observed well with a little patience. In the morning the locomotive already stands under steam before the first train is brought into position. Through the day, runs and short stops alternate, during which checks are made, oiling takes place and water is taken on. Towards the end of the day come the tasks nobody sees: cleaning the fire, removing the ash, replenishing supplies for the next day. Anyone who follows the operation over several hours therefore gets a completely different picture from someone who only photographs a single train passing by – and understands better why steam operation is labour-intensive.
You experience similar routines at other steam operators: at the Saxon Steam Railway Company, at the Harz narrow-gauge railways, or on the island at the Borkum light railway. The scale of operations differs, the basic principle does not. In Mecklenburg itself, the MPSB recalls the once far-reaching narrow-gauge network of the region.
Photographing without getting in the way
Are you prepared for the visit?
- Current running days and service checked directly with the operator
- I know which areas are publicly accessible
- In the street section I pay attention to ordinary road traffic
- I keep my distance from the track, the locomotive and work areas
- I note down locomotive, train, place and time together
- I have checked the direction of light for my intended shot
How to turn an observation into a usable photograph is described in the guide How to take good photos of trains; how to properly log your observation afterwards is shown in the guide to reporting sightings.
The street is not a photo spot
In the street section you share the space with cars, cyclists and pedestrians – and with a train that cannot swerve. Never stand on the track or in its path, not even briefly. Track areas, the shed and operational installations are private property and off limits. The basic rules are set out in the article Safe distance from the track.
Common mix-ups
- Narrow gauge meaning heritage railway – narrow-gauge railways too fulfil a real transport function.
- Steam meaning a special working – at this operation steam is the defining form of traction, not the exception.
- Street section meaning tram – a railway running through the street is nonetheless nowhere near a tram.
- Historical vehicle meaning withdrawn – older vehicles here are in daily service.
- A photo from last year still counting – vehicle rosters and timetables change seasonally.
Conclusion
The Molli seaside railway combines three things you rarely find together: narrow gauge, steam traction and a section right through the middle of the street. Anyone who visits therefore sees not just a train, but a complete operating routine – from lighting the fire, through taking on water, to ashing out in the evening.
In short
The name states region and purpose, the technology sets the frame: narrow gauge plus steam. And because steam operation is stock-based operation, the pauses at the water crane are often more interesting than the run itself.

Frequently asked questions
What does "Bäderbahn" mean?
The term describes railways built for traffic to seaside resorts. Their purpose was touristic from the very start: guests were meant to travel comfortably from a connecting point on the main network to the coast. The name is therefore a statement of purpose and, at the same time, a piece of transport history that still lives on in the company name today.
Why does the train run through a street?
Because in Bad Doberan the line runs through a built-up area and the track lies within the street there. Such sections have become rare and are part of what makes the railway so appealing. For everyone involved this means: heightened attention, slow running, and the clear rule that pedestrians must give way to the train.
How much water and coal does a steam train need?
Considerably more than most people expect – and both have to be replenished en route. Water is taken on at water cranes, coal topped up at a coaling point. The actual amounts depend on the locomotive design, train load, route profile and driving style. What matters is the principle: the stock is limited and helps determine the running of operations.
What happens when taking on water?
The train stops at a water crane, a swing arm is brought over the filler opening of the tender or water tanks, and the supply is topped up. This takes a few minutes and is one of the few moments when operations come to a standstill. For photographers it is a rewarding situation – from a safe distance and from a publicly accessible area.
Why does the locomotive stand under steam for so long in the morning before departure?
Because a steam locomotive is not ready for service at the push of a button. Lighting the fire and slowly heating the boiler takes hours and has to be done carefully to avoid material stress. At the end of the operating day the reverse process follows: putting out the fire, removing the ash, servicing the equipment. Steam operation therefore costs extra time both before and after every run.
Does the railway run all year round?
The service, running days and vehicle roster change seasonally and with the operating programme. So don't rely on older information from forums or guidebooks; check the current status directly with the operator. That applies especially to special workings and to the question of which locomotive is in service on a given day.
Where am I allowed to stand for photography?
Only in publicly accessible areas – on pavements, squares and designated platform areas. The track itself, operational installations and the shed area are off limits. In the street section, ordinary road traffic rules also apply: you are standing there among vehicles, cyclists and pedestrians, not at a cordoned-off photo spot.
Can I see this railway's vehicles on the standard-gauge network?
No. Narrow-gauge vehicles do not fit mechanically onto standard-gauge track. A change of location would only be possible as cargo on a road or rail transport and is a rare exception. That is an important difference from standard-gauge heritage railways, whose vehicles can also run on the general network.
