Nassauische Touristenbahn e.V.

The Nassauische Touristenbahn runs heritage services on the Aartalbahn, one of the longest surviving branch-line routes in Hesse. Scheduled local services haven't run there for decades – what's runnable and what isn't has changed repeatedly over the years.

Key takeaways

  • The Aartalbahn is a surviving route, not a through transport corridor – there's no scheduled local service there.
  • What's runnable changes: the current status comes only from the society, never from older sources.
  • The operator is a society that carries running operations, line maintenance and vehicle upkeep on a voluntary basis.
  • Standard gauge without overhead line means diesel – electric traction is ruled out.
  • Even without a train the visit is worthwhile: preserved station buildings and installations are a subject in their own right here.

Business areas

Heritage services – trips on the runnable sections of the Aartalbahn
Line maintenance – vegetation clearance, track structure and level crossings as an ongoing task
Vehicle upkeep – railcars, coaches and small locomotives maintained in-house
Special trains – charter and themed trips subject to availability
Advocacy – keeping the route intact against dismantling and redevelopment

History at a glance

1870sThe Aartalbahn is built as a link between the Wiesbaden area and the Lahn valley – a branch line through the narrow valley of the Aar.
1900sThe line becomes the backbone of transport in a region of spa towns, agriculture and mining.
1980sScheduled passenger services end section by section. The route survives but loses its transport function.
1990sVolunteer structures bring heritage trains back and halt the dismantling.
2000sReactivation, redevelopment and responsibility remain permanently disputed – the runnable extent fluctuates accordingly.
TodayHeritage services run on whichever sections are operationally usable; the society announces the current extent as it stands.

How to recognise Nassauische Touristenbahn e.V.

Does the train really belong to Nassauische Touristenbahn e.V.?

Tick off everything that applies to the vehicle in front of you.

  • No overhead wire – only diesel operation is possible on the whole route
  • Preserved branch-line architecture: station buildings and signal boxes in their original form
  • A narrow, overgrown valley – the route follows the Aar rather than the shortest line
  • Track condition varies by section, from runnable to overgrown
  • Short heritage formations instead of long trains
  • Society staff in their own clothing rather than a corporate uniform
  • At Wiesbaden, proximity to regular services, but with no through connection in the timetable

Strengths and weaknesses

What the company stands for

  • A continuously surviving branch-line route, rarely matched elsewhere in Hesse
  • Preserved station buildings and railway installations are a subject in their own right, even without a train
  • Trips run with no competing regular service – the heritage train has the picture to itself
  • Easily reached from the Rhine-Main area and combinable with other destinations
  • Slow trains and tight bends produce unusual perspectives

Where it falls short

  • The runnable extent changes – information found online goes out of date here especially fast
  • Very few running days; without a current date the trip isn't worth it
  • The narrow valley and heavy vegetation limit photo locations considerably
  • No steam operation in the regular programme
  • The ongoing dispute over reactivation and redevelopment makes the future hard to assess

Updated: August 2026 – Between Wiesbaden and the Lahn valley lies a railway line that arguably shouldn’t still exist: a branch-line route surviving continuously over a great length, with no scheduled traffic. The Nassauische Touristenbahn runs heritage services there – and alongside that does the work without which such a route would vanish under vegetation within a few years.

What makes the Aartalbahn unusual

Most disused branch lines in Germany have vanished: dismantled, built over, turned into cycle paths. The Aartalbahn is one of the exceptions. Its route has survived continuously over a considerable length, complete with station buildings, outbuildings and engineering structures – a condition barely found on active lines any more, since almost everything there has been modernised in recent decades.

What it isn’t: a continuously operated railway. Scheduled local services have been gone for decades, and the runnable extent has shifted repeatedly over the years. That’s exactly where the difficulty lies for any description: what’s true today can be wrong in two years.

Everything “disused” can mean

On lines like this, one term is constantly misused. Between a line with no timetable and a dismantled line lie several states that mean completely different things operationally and legally.

Status How you can tell What it means for you
In service, no timetable bright rails, well-kept crossings a train can come at any time
Heritage services track clear, vegetation cut back trains only on announced dates
Operationally closed vegetation on the track, secured crossings no trains, but the route remains railway land
Decommissioned rails still in place, railway purpose lifted legally no longer a railway installation
Dismantled ballast bed or cycle path nothing left to see

The practical point: even a route with no visible traffic almost always remains railway land. Anyone stepping onto it because “nothing runs here anyway” is wrong, both operationally and legally.

Current status beats an old description

On this line, information goes out of date faster than elsewhere. The state of the route, runnable sections and dates all change; older forum posts and maps often show a status from several years back. Before every visit, check what the society currently states itself – here that's not a formality, but the difference between a running day and an empty station.

Maintaining the route is more work than running it

At most heritage railways, running operations are the biggest item of effort. On a long branch-line route, it’s line maintenance. Vegetation grows fast, and a railway line with no regular traffic becomes unusable within a few years. On top of that come level crossings, drainage, bridge structures and safety systems – all tasks that arise even when not a single train runs.

That’s why a society like this ties up a large part of its volunteer effort in work no visitor ever sees. Anyone wondering why so little runs on such a long line finds the answer here. At shorter operations such as the Hessencourrier, the ratio of maintenance to running operations is different.

Which vehicles you can expect to see here

Heritage services on branch lines of this size run on diesel. Two-axle Uerdinger railbuses shape the picture, built for exactly this kind of line: low axle load, minimal crew needs, a short unit. For locomotive-hauled trains, machines of the V 100 class and small locomotives of the V-60 family come into play.

It’s worth comparing this with what runs a few kilometres away in regular service. On the region’s active lines, modern diesel railcars define the picture, while on the Aartalbahn stand vehicles long since withdrawn elsewhere. Older DB railcars such as the Class 628 mark the transition between the two worlds.

We don’t name individual vehicle numbers here. At societies, fleets change through hire, overhaul cycles and restoration work – if you need one for your logbook, read it off the vehicle itself.

Check the current operating status

Which section is running changes. Get this information directly from the society, not from older sources.

Route your journey via the Rhine-Main area

Wiesbaden and Limburg are the obvious starting points for a journey without your own vehicle.

Calculate the light window in the valley

Narrow, wooded valleys fall into shadow early. Without planning around the sun's position, you'll be standing in shadow even though the sun is shining.

Treat the railway installations as their own subject

Preserved station buildings and outbuildings are a subject in their own right here – even when no train is running.

Log your sighting with a date

Because the operating extent changes, a dated logbook is later your only reliable reference.

How much of the route is currently usable?

On this line, that's the decisive figure. Enter what the society states for your date.

You need to enter the numbers yourself – we deliberately give none here, since they change.

Photographing on a line with no regular service

The big advantage is calm: no clock-face service gets in the way, no other train sits in the shot at the crucial moment. The heritage train has no competition on its running day, and you can concentrate on it entirely.

There are two downsides. First, the narrow, wooded valley limits the number of usable locations considerably – open sightlines are scarce, and where one exists it’s often already in the slope’s shadow by the afternoon. Second, opportunities are few: if a shot fails, you don’t wait ten minutes but until the next date. Anyone dealing with that works with prepared locations and test shots rather than improvising on site – the heritage railway guide covers how to prepare.

A dormant line is not a footpath

Even where no train has run for years, the route remains railway land. Works, transfer and inspection movements aren't announced, and in a narrow valley an approaching vehicle is hard to hear. Stay on public paths and at level crossings – the rules are set out in the article on safe distance from the track.

Does this suit what you’re after?

Yes, if …

  • preserved branch-line installations interest you just as much as running trains
  • you're prepared to plan the visit around the current operating status
  • you're already in the Rhine-Main area and want a quiet contrast

Check carefully, if …

  • you're hoping for a specific section that wasn't recently in use
  • you only have a narrow window of time – the light window in the valley is short
  • you want to reach several locations without a car

No, if …

  • you expect steam or electric traction
  • train frequency matters more to you than a single working
  • you want to rely on older descriptions of the line

For vehicle variety on the same day, the distance is short: Frankfurt Hauptbahnhof delivers more classes in an hour than the Aartalbahn does in a season, and the Middle Rhine valley at Boppard adds freight traffic in dense succession.

Verdict

The Nassauische Touristenbahn is an unusual case among Germany’s heritage railways. It doesn’t run on a short surviving remnant but keeps a long branch-line route open whose future has been disputed for decades – with an effort that mostly falls outside the running operation itself.

For spotters that means: the visit needs preparing, and the most important piece of information isn’t the timetable but the operating status. Anyone who checks that beforehand, calculates the light window in the valley and treats the preserved railway installations as a subject in their own right gets something here that barely exists any more in Germany’s railway scene.

Verdict in brief

Heritage services on a surviving but not continuously runnable branch-line route. Diesel, few dates, a shifting operating extent – and railway installations that are a subject even without a train.

Dated sightings beat old route maps

Where the operating extent keeps changing, your own logbook is the most reliable source.

Summary

  • The society keeps a branch-line route running in the Aar valley whose future has been disputed for decades.
  • The heritage service is run by volunteers and therefore limited to a handful of dates.
  • Photographically, the narrow valley offers unusual perspectives but few open sightlines.
  • Anyone visiting the line should check the current operating status – older information here is almost always out of date.

Frequently asked questions

Where does the Aartalbahn run?

In the valley of the Aar, between the Wiesbaden area and the Lahn valley near Diez and Limburg. The route follows the river through the Taunus foothills, with tight bends and several engineering structures. It's one of the longest continuously surviving branch-line routes in Hesse – though surviving doesn't mean runnable everywhere.

Does a regular regional train run there?

No. Scheduled local passenger services were withdrawn decades ago and have not returned. What runs on the route is heritage traffic. Further afield, companies such as Vias and the Hessische Landesbahn handle regional services – just not on this line.

Which sections can I actually see trains on?

That's the question with no permanently valid answer. The runnable extent has changed repeatedly over the years, depending on the condition of the line, permits and responsibilities. We deliberately don't list sections here, since it would very likely be out of date. The current status comes only from the society itself.

Who runs the heritage railway?

A registered society. Driving, train guarding, workshop work and above all vegetation clearance along the route are handled by members in their free time. On a long branch-line route, line maintenance is the biggest item of effort – considerably bigger than the running operation itself.

Is there steam operation?

Not in the regular programme. The line is run with diesel; steam can at most be expected at announced special events with guest locomotives. Anyone specifically after steam in the Rhine-Main and Middle Rhine area is better served by the Vulkan-Expreß in the Brohl valley or the Kuckucksbähnel in the Palatinate.

Which vehicles can I see there?

Typical of heritage services on branch lines are Uerdinger railbuses, along with diesel locomotives for locomotive-hauled trains, for example from the V 100 class or the V-60 family. We don't name specific vehicle numbers: at societies, fleets change through hire, overhaul cycles and restoration work.

Is a visit worthwhile even without a train running?

Unusually, yes. Along the route, station buildings, platform installations and outbuildings survive in a condition rarely found on active lines – there, almost everywhere has been modernised in recent decades. For architecture and infrastructure photography, that's a subject in its own right, regardless of whether a train runs that day.

Why is there so much dispute about the line?

Because a surviving route in a densely populated area touches several interests: reactivation for local transport, use as a cycle path, heritage operation and heritage conservation are partly at odds with each other. Such conflicts drag on for decades, and there's no reliable forecast for how they'll resolve. For you at the lineside, that mainly means: check the current status rather than relying on older descriptions.

How do I photograph in a narrow valley?

With an eye on the clock. Narrow, wooded valleys have short windows of usable light, because the slopes fall into shadow early – planning around the sun's position is not a nicety here but a precondition. Second, it's worth deliberately using tight bends: they allow perspectives in which the locomotive and train are visible at the same time.

Am I allowed to walk the route when nothing is running there?

No. A route with no traffic isn't open ground: it remains operational railway land, and works or transfer movements aren't announced. Photograph from public paths, roads and level crossings. What applies is set out in the article on safe distance from the track and on house rules on railway land.
