Key takeaways
- This is not a railway. The entire operation runs under tramway law – including the forest section outside town.
- Metre gauge, not standard gauge: the track is 1000 mm wide, ruling out any vehicle exchange with railway lines.
- Two operations in one name – Gotha's city services and the interurban route to Tabarz.
- Gotha was a manufacturing town, not just an operator: tram cars for the whole of East Germany came from here for decades.
- There's no railway-operator counterpart to this brand, because a tramway doesn't need a railway licence.

How to recognise Thüringerwaldbahn und Straßenbahn Gotha
Does the train really belong to Thüringerwaldbahn und Straßenbahn Gotha?
- Metre gauge – the track spacing is noticeably narrower than a standard-gauge railway
- Its own dedicated track alongside the road on the interurban section – looks like a light railway, is legally a tramway
- Tatra cars and their conversions with a characteristically narrow body and short articulated units
- Tram signals instead of main and distant signals – a reliable distinguishing feature
- Low stop edges, sometimes just a step onto a path or the roadside
- Passing loops on single-track sections – unusual for a tramway, but everyday here
- Historic cars at weekends and during events, often in older liveries
Strengths and weaknesses
What the company stands for
- One of the few interurban tramways left in Germany – the operation type itself is already rare
- The forest setting and dedicated track offer shots no city route can provide
- Vehicles from the Tatra family are becoming rarer nationwide and are still in everyday use here
- Short route, easily covered in a single day
- Direct historical link to the town as a former tram-building centre
Where it falls short
- Not a railway operation – anyone looking for locomotives or freight traffic is entirely in the wrong place
- A very narrow range of types in everyday service
- The forest section is only reachable on foot in places, and photo spots take time to reach
- In summer, dense foliage makes many locations barely usable
- Historic vehicles run irregularly and without a reliably plannable timetable
Updated: August 2026 – Between Gotha and Tabarz, a vehicle runs for more than twenty kilometres through open country and along forest edges, stopping at small villages before ending at the foot of the Thuringian Forest. It looks like a light railway. Legally, though, the Thüringerwaldbahn is a tramway from the first stop to the last – and that very contradiction is what makes it interesting.

Interurban tramways are disappearing. Document the car number, section and date while they still exist.
Two operations, one name
The unwieldy double name is no accident, but an accurate description. It refers to two things that are operationally linked but work in entirely different ways: tram services within the town of Gotha, and the interurban route that runs from there into the Thuringian Forest.
The town section is unspectacular and works like any medium-sized tram operation. The interurban section is not. It runs on its own dedicated track, single-track in places with passing loops, through countryside rather than streets. Operations like this once existed in Germany by the dozen. Few remain.
Important for classification: there is no railway operator attached to this brand. A tramway doesn’t need a railway licence, doesn’t run trains in the railway-law sense, and so doesn’t appear in railway-operator directories at all. Anyone looking here for a vehicle keeper marking (VKM) on the data panel is looking for the wrong thing.
Metre gauge: the decision that defines everything
The track is 1000 mm wide. That sounds like a minor technical footnote, but it’s the single most defining choice in the whole system. Metre gauge means: no vehicle exchange with the railway network, no transfers onto standard-gauge lines, no dual-gauge solution like the Saarbahn. The operation remains permanently self-contained.
Conversely, metre gauge allows tighter curves, narrower formations and cheaper construction – exactly what an interurban line needs to pass through established villages. The decision was right for its time and remains the reason this route looks the way it does today.
| Feature | Thüringerwaldbahn | Classic branch line | Dual-gauge light rail |
|---|---|---|---|
| Legal framework | Tramway law | Railway law | Both, section by section |
| Track gauge | 1000 mm | 1435 mm | 1435 mm |
| Signalling | Tram signals | Main and distant signals | Depends on the section |
| Network connection | None | Present | Present |
| Vehicles | Tram cars | Railcars or loco-hauled trains | Dual-gauge cars |
Signals tell you the type of operation in two seconds
If you're unsure whether you're looking at a railway or a tramway, don't look at the vehicle – look at the signals. Bar and dot signals mean tramway operation; main and distant signals mean railway. This works even where a line runs through woods and fields and looks, visually, exactly like a branch line.
Gotha was not just an operator, but a manufacturer
The second historical thread leads away from the route and into the works halls. For decades, Gotha was one of the most important centres of tram building in East Germany. Vehicles for operators across the whole of East Germany came from here; the term “Gotha car” is still current today, even though production ended in the 1960s in favour of other sites.
After that, vehicles from Czechoslovak production took over the role – cars from the Tatra family, which still shape the picture of East German tram operations today. In Gotha they still do: types related to the Tatra KT4D and the low-floor conversions derived from them are in everyday service. Preserved Gotha vehicles, on the other hand, are more likely found in collections, such as the Leipzig-Möckern Tram Museum or the Hannover Tram Museum.
Choose your section
Town route or interurban section? Both give completely different pictures. The forest section takes noticeably more time.
Check sightlines in advance
In summer the forest closes in. Maps and satellite imagery help you find open spots beforehand.
Use the passing loops
On single-track sections, cars cross at fixed points – that's where you get two vehicles in one shot.
Note the car number
The types repeat quickly. Only the individual number makes sightings analysable over the years.
Plan your return trip
Frequencies outside town are sparser than within it. Without the timetable in mind, you'll wait longer than planned at the forest edge.
Do you have both faces of the route?
The interurban section is what sets this operation apart from every other city network.
Keep town and forest separate
Two sections, two worlds of subjects – the Traintrack app keeps them cleanly apart.
Tram or branch line – how to tell
It's a tramway operation if …
- bar or dot signals control the movement
- the stop has only a low edge or none at all
- the vehicle is a tram car without railway-style couplers and buffers
Easy to mix up if …
- the line runs on its own dedicated track through open countryside
- single-track sections are operated with passing loops
- the trackbed is ballasted like a branch line
It would be a railway if …
- main and distant signals were present
- the line had a connection to the railway network
- standard-gauge vehicles ran on it
Anyone planning a full day in the region shouldn’t view the forest tramway in isolation. In southern Thuringia, the Süd-Thüringen-Bahn runs a complete branch-line network with a uniform diesel-railcar fleet, the Erfurter Bahn is active around Erfurt, and within reach lies the Oberweißbacher Bergbahn, a funicular with a wagon lift platform that has no equivalent anywhere else. Three types of operation, three legal frameworks, one federal state – as a combination, that’s more rewarding than any single route on its own. Historic vehicles can be planned for deliberately, as the article Finding historic trams shows.
This distinction is more than a formality. It determines which rules apply to you, which data sources will help, and which category your sighting should fall into. Anyone looking for the forest tramway in a railway database will search in vain – it belongs in the tram world, as the article Tram spotting in Thuringia describes.
A dedicated track is not a footpath
The interurban section runs so unobtrusively through the landscape in places that it looks like a path. It is operational railway land. Photograph from public paths and roads, keep your distance, and expect a tram car to approach more quietly than you expect. More on this in Recognising tram types and Are you allowed to photograph trams?.
Verdict
The Thüringerwaldbahn isn’t a railway subject, and doesn’t want to be one. Its value lies in preserving a type of operation that’s disappeared almost everywhere else: the interurban tramway with its own dedicated track, metre gauge and passing loops.
For documentation, that means: pick the right category, note the car number, record the section. And for planning: spring or autumn, when sightlines are open and the light is low enough to make the route stand out from the landscape.
Quick verdict
A tramway operation that looks like a branch line: 1000 mm gauge, BOStrab, no railway operator. The special part isn't the vehicle, but the character of the route between Gotha and Tabarz.
Document rare networks first
Interurban tramways are dwindling remnants. What you record today becomes tomorrow's source.
Summary
- The forest tramway is a type of operation that's almost gone from Germany: a genuine interurban tramway with its own dedicated track over more than twenty kilometres.
- Legally it remains a tramway throughout, even though it looks like a branch line over long stretches – that contradiction is its real story.
- In terms of vehicles, the operation runs on the Tatra family and its conversions, supplemented by historic cars for special runs.
- Anyone travelling here should plan around light and season, not vehicle types – those barely change.
Frequently asked questions
Is the Thüringerwaldbahn a railway?
No. It's a tramway operation throughout, under Germany's tramway construction and operating regulations, even on the long section outside built-up areas. That's also why there's no railway operator listed for this brand in operator directories. Exactly where the line falls between these categories of operation is explained in the article Light rail or tram – what's the difference.
What gauge does the forest tramway use?
1000 mm, i.e. metre gauge. That's why a vehicle exchange with the standard-gauge railway network is technically ruled out – unlike dual-gauge light rail systems such as the Saarbahn, which runs on standard gauge and can therefore switch onto railway lines at all. The forest tramway remains permanently a self-contained system with no connection to the wider rail network.
How long is the route to Tabarz?
It runs for a good twenty kilometres from Gotha's town area to the edge of the Thuringian Forest. That makes it one of the longest continuous tram routes in Germany. Large parts run on their own dedicated track alongside or away from the road, single-track in places with passing loops.
What vehicles run there?
Day to day, cars from the Tatra family dominate, especially types related to the Tatra KT4D, along with low-floor conversions derived from them, of the kind several East German operators have developed – similar to the KTNF6. There are also heritage cars that run on special services. Which cars are currently in circulation changes, so a fixed fleet list is deliberately not given here.
What does Gotha have to do with tram building?
A great deal. Gothaer Waggonbau supplied tram cars to operators across East Germany for decades; "Gotha cars" remains a fixed term among tram enthusiasts to this day. Production ended in the 1960s. Preserved vehicles of this type can be found in collections such as the Leipzig-Möckern Tram Museum.
Do historic cars run there too?
Yes, but irregularly. Heritage cars run at events, anniversaries and special services. There's no reliable timetable for this, and made-up dates help no one – check the operator's own announcements. How to track down historic trams in general is covered in the article Finding historic trams.
Where are the best photo spots?
On the interurban section, where the line runs on its own dedicated track through open countryside or along the forest edge. In the town, classic street tram photography dominates, with all the usual problems: parked cars, poles, hard shadows. Tips on this are in Photographing trams in the street.
Am I allowed to just photograph the forest tramway?
From public space, yes in principle. On operational land, on the track and inside vehicles, however, the operator's rules apply. A dedicated track is not a footpath, even where it looks like one in places. The legal framework is summarised in the article Are you allowed to photograph trams?.
What else is there on rails in the area?
Quite a bit. In southern Thuringia, the Süd-Thüringen-Bahn runs a complete branch-line network, the Erfurter Bahn is active around Erfurt, and the Oberweißbacher Bergbahn is a funicular with a wagon lift platform that has no equivalent anywhere else. Anyone planning a weekend trip gets three completely different rail systems packed into a small area.
What's the best time of year?
Spring and autumn. In summer, dense foliage covers many spots on the forest section; in winter, light and access are limited – though snow makes for a strong subject there. Since the operation runs year-round, it's less about seasonal timetables and more about sightlines and the angle of the sun.

Süd-Thüringen-Bahn (STB)
The Süd-Thüringen-Bahn is one of the few brands with an operating company of the very same name behind it. Its network lies between the Rennsteig and the Rhön, its fleet consists of practically a single railcar type – and its operational hub happens to be the town with Germany's best-known steam locomotive works.
BrandErfurter Bahn
Erfurter Bahn is a brand name, not an operating entity. Behind it stands a municipally backed group of companies with several entities that share vehicles, workshops and staff. Anyone who wants to log a sighting properly reads the data panel, not the lettering.
BrandOberweißbacher Bergbahn
The Oberweißbacher Bergbahn is a tourist name for two operationally linked facilities: a standard-gauge funicular with a freight platform, and a short level line up on the plateau. Both are run by a company whose name appears nowhere on the vehicle.
Heritage railwayStraßenbahnmuseum Leipzig-Möckern
The Straßenbahnmuseum Leipzig-Möckern isn't a showroom but a historic tram depot, from which real trains run out onto the network on event days. It runs on 1,458 millimetres – a special gauge found almost nowhere outside Leipzig.
