Key takeaways
- Hanning & Kahl builds no vehicles, but brake technology and point drives for rail-bound local transport.
- The track brake is the most visible component – a dark bar close above the rail, on almost every tram vehicle.
- At the lineside you recognise point technology by the drive housing, point signal and induction loop, not by the vehicle.
- Suppliers don't determine a sighting. For identifying a vehicle, type, operator and car number still count.
- Little is documented about the company itself; what can be described reliably is above all its role in the system.

History at a glance
How to recognise Hanning & Kahl
Does the train really belong to Hanning & Kahl?
- Track brake – the long, dark bar between the wheels, a few centimetres above the rail
- Point drive housing in the street track – a flat cover beside or between the rails at the point blade
- Point signal on the mast: the white bar, arrow or dot that shows the driver the set position
- Induction loops and antennas ahead of the point – this is where the vehicle reports its intended route
- No manufacturer logo on the vehicle – supplier parts carry at most a small nameplate
- Brake markings on the car body side name the brake type, not the supplier
- Spring-loaded actuator on the brake calliper – the cylindrical fitting that applies the brake without air pressure
Strengths and weaknesses
What the company stands for
- The technology is present in almost every German tram network
- Point drives are often easy to see from the platform and safe to photograph
- Track brakes can be documented cleanly on stationary vehicles
- Local transport technology changes slowly – learned features stay valid for a long time
- Understanding the components makes vehicle comparisons between cities much more precise
Where it falls short
- The manufacturer is practically never identifiable on the vehicle
- There's hardly any solid public source on the company's history
- Supplier parts get replaced during modernisation – conclusions about the build year are unreliable
- Without access to workshop data, every attribution remains a guess
- In the mainline rail sector the company plays a much smaller role than in local transport
Updated: August 2026 – Ask ten tram spotters who built their favourite tram, and you’ll get ten vehicle manufacturers named. Ask who supplied the brake, and it goes quiet. Hanning & Kahl from Oerlinghausen stands for exactly this level: technology found in almost every network that nobody looks for in the photo all the same.

What a supplier without its own vehicles does
The vehicle industry has a structure that’s rarely visible from outside. At the top stand the systems houses that supply complete vehicles. Below them a second tier operates: firms that build individual assemblies and sell them to several vehicle manufacturers.
Hanning & Kahl belongs to this second tier, and specifically as a specialist with two clearly separated fields: brake technology for tram and light rail vehicles, and drive and control technology for points in local transport. That’s an unusual combination, since one sits in the vehicle and the other in the track.
The economic logic behind it is the niche. A global group like Siemens Mobility builds complete systems, and Knorr-Bremse dominates the mainline-rail brake market; a specialist, by contrast, optimises one assembly so thoroughly that several competitors buy it from them.
The track brake: the most visible invisible component
Anyone photographing a tram from the side and going low enough almost always gets it in the shot: a long, dark bar between the wheels, only a few centimetres above the rail. That’s the track brake, and it’s the most characteristic component in the running gear of every tram vehicle.
Its principle sets it apart from anything hanging off a mainline locomotive. Wheel and disc brakes need adhesion friction between wheel and rail; in wet conditions that’s not enough. The track brake lies directly on the rail. For tram operation with crossings and short sighting distances, that’s essential.
A comparison is worthwhile: on a Tatra KT4D from East German production the brake sits differently in the running gear than on a low-floor tram like the NGT8D, the Flexity Berlin or the TW 2000 of ÜSTRA. Anyone who knows both designs can identify a vehicle even when the front gives nothing away.
A component you photograph from a crouch
The track brake sits so low that it disappears in standard shots taken from an angle above. Anyone wanting to document it crouches down at a stationary vehicle and photographs parallel to the rail. How to keep the composition working while doing so is described in the article Photographing trams.
The point in the street track – a photographic subject in its own right
The second field sits not on the vehicle but beneath it. A local-transport point in the street has to be built flat, withstand lorries, tolerate road salt, and be set from the vehicle.
At the lineside you recognise this by three elements that always appear together:
| Element | Where it sits | What it’s for | How you recognise it |
|---|---|---|---|
| Point drive | at the point blade | moves the blade | flat housing or cover in the road surface |
| Point signal | on the mast or overhead line support | shows the set position | white bar, arrow or dot on a black background |
| Setting request | a few metres before the point | vehicle reports its intended route | induction loop in the track or antenna above it |
| Fail-safe mechanism | inside the drive | returns the point to its default position | no visible outside component |
This combination can be seen at practically every branching stop, and it’s one of the few railway subjects you can document completely from a pavement.
Network details belong in the logbook
Point connections, special workings, diversions – with Traintrack you keep an eye on your home network.
How to read local transport technology at the lineside
Find the point blade
Look for the spot where the track splits. The drive sits right next to it, usually flush with the road surface.
Look for the signal on the mast
A white bar, arrow or dot on a dark background shows the driver the set position. It's not a railway signal and follows its own rules.
Locate the setting request
A few metres before the point an induction loop sits in the track, or an antenna hangs above it. This is where the vehicle requests its direction of travel.
Look at the running gear on a stationary vehicle
At the stop you can study the track brake at leisure. Note its position, length and mounting – they vary by vehicle generation.
Log the vehicle properly
Car number, type, line, location. The component is context – the sighting itself still hangs on the vehicle.
Have you captured the whole installation?
Only together do four individual parts become an understandable installation.
Works, transfer and test runs in local transport
Trams run workings that appear in no timetable too. A new vehicle arrives in the city by low-loader and is moved through the network for the first time at night – often at walking pace, with an accompanying crew and open doors. Such test runs are the local-transport equivalent of a locomotive’s acceptance run.
Particularly relevant for brake technology are the brake trials. A new vehicle has to prove its braking distances, and that happens on closed-off sections of track, often at night or on a quiet Sunday morning. The track brake is actually triggered during this – a sound you don’t forget.
Added to this are everyday transfer and workshop runs: vehicles between two depots, driver-training cars and works vehicles. They run without passengers, often with a different destination display or none at all. Anyone who knows their home network recognises these runs immediately – the article on special workings gives pointers.
Where supplier knowledge helps and where it misleads
Component knowledge helps, when …
- you want to tell two similar vehicle types apart by their running gear
- you want to explain why a modernised vehicle looks different from before
- you're systematically documenting a network's point technology
Be careful, when …
- you want to infer the build year from a component – components get swapped out
- two cities ordered the same vehicle family with different equipment
- a vehicle has visibly been rebuilt
It doesn't help, when …
- you note the supplier down as the vehicle's manufacturer
- you want to justify a sighting without a car number through components
- you infer the operator from a component
The most important rule for this page: a supplier appears in no sighting. It explains technology, but it doesn’t identify a vehicle. Anyone entering it in a collection confuses a component’s origin with a vehicle’s identity.
Street track is traffic space
Points in the street sit in the middle of moving traffic. Anyone stepping onto the carriageway or the track for a detail shot endangers themselves and others – trams are quiet and have no way to swerve. Photograph from the pavement or platform; the basic rules are set out in the article on keeping a safe distance from the track.
Verdict
Hanning & Kahl is a good example of how much of the rail industry happens outside the well-known names. The company appears in no sighting list, but shapes the behaviour of vehicles in almost every German tram network.
There’s little solid public substance on the company itself, and that’s deliberately not filled in here with guesses. What can be described is the role: a specialist between vehicle and track whose products you can see once you know where to look.
Quick verdict
A local-transport supplier with no vehicles of its own. The technology becomes visible in the track brake and point drive – for vehicle identification, type and car number still count.
From vehicle type to network knowledge
Anyone systematically logging their tram network sees changes first. Traintrack helps with the sorting.
Summary
- Local transport suppliers work invisibly: their products sit inside vehicles built by other manufacturers and operated by yet other companies.
- Anyone documenting trams gains from knowing the components – brake and point reveal more about a network than any livery.
- Point technology in street track is its own, barely noticed photographic subject right next to the platform.
- For this company: the operational role can be described well, the company chronicle cannot.
Frequently asked questions
Does Hanning & Kahl build its own trams?
No. The company is a supplier and delivers components to vehicle manufacturers and transport operators. The vehicles themselves are built by firms such as HeiterBlick, Alstom or Siemens Mobility. A tram vehicle is therefore always the product of several companies at once.
What is a track brake?
A brake magnet that, when triggered, is lowered onto the rail and adheres there. Unlike wheel or disc brakes, it doesn't depend on the wheel's adhesion friction and therefore achieves very short braking distances. It hangs visibly between the wheels, a few centimetres above the rail head. It's present on almost every German tram vehicle, for instance on the NGT8D or the TW 2000.
How do I recognise a point drive in the street track?
By a flat housing or cover right at the point blade, usually flush with the road surface. Almost always accompanying it is a point signal on the mast that shows the driver the set position, and an induction loop or antenna a few metres before the point. These three elements together are the surest sign of a remotely set local-transport point.
Is the supplier even relevant to my sighting?
Not for identifying the vehicle. A sighting is made unambiguous by vehicle type, operator and car number, not by the components fitted. Knowing the components helps you nonetheless: it explains why identical vehicles sound, brake and look different in two cities. The basics of identification are in the guide to identifying classes.
Why is there no manufacturer name on the components?
Because the vehicle manufacturer acts as the supplier towards the transport operator. The components are part of its product. There's usually a small nameplate nonetheless, but it sits in hard-to-reach spots in the running gear. From the outside the supplier is thus practically never identifiable.
Does the company also work for mainline rail?
The clear focus lies on rail-bound local transport – tram, light rail, partly U-Bahn. In the mainline rail sector other suppliers dominate, above all Knorr-Bremse for brake systems and Vossloh for point technology. There are no reliable public figures for the exact market split.
Where can I photograph point technology safely?
At stops with a point connection and in the street ahead of larger junctions. There you stand on public ground, have a clear view of the drive and signal, and disturb nobody. What matters is keeping distance from the carriageway and the track – the article on photographing in the street gives pointers.
What's the difference between tram and railway points?
Design and control. Tram points sit in the street, are built flat, are often requested from the vehicle, and are mostly not signalled under railway law. Railway points belong to a signal box and are embedded in route logic. What that means operationally is explained in the article on signal boxes and operating technology basics.
How old is the company?
There's no figure that could be reliably reproduced here. The Oerlinghausen location and the focus on local-transport technology are documented, but a solid company chronicle with year dates isn't cleanly available publicly. The timeline on this page therefore deliberately covers the development of the technology field rather than the company's history.
How do I find out which vehicles run in my city?
Via the transport operator's type lists and via the car numbers on the front. Networks such as those of ÜSTRA Hannover, Rheinbahn Düsseldorf or the Dresden transport operator are well documented. The article on tram types is a good introduction to telling types apart.

The operational level in the railway operator database
Who actually runs the trains, with keeper markings and identifying features on the vehicle.
ÜSTRA Hannoversche Verkehrsbetriebe AG
ÜSTRA Hannoversche Verkehrsbetriebe AG runs urban local transport in Hanover. Tunnel sections and high platforms shape the look of the light rail system.
Local & regionalRheinbahn AG Düsseldorf
Rheinbahn AG operates urban local transport in Düsseldorf. Its rail vehicles carry operational coach numbers – and they reveal more than you might think.
Local & regionalDresdner Verkehrsbetriebe (DVB)
With trams, almost everything works differently than with railways: different operating rules, different numbers, different photo rules. What that means for sightings in Dresden.
Local & regionalBremer Straßenbahn
Trams follow different rules from railways – from the operating regulations to the vehicle number. At Bremer Straßenbahn, this difference becomes tangible.
Local & regionalRostocker Straßenbahn
The Rostocker Straßenbahn runs Rostock's urban rail transport. Its destination sign tells you more about a working than any other feature on the vehicle.
Local & regionalStadtwerke Bonn (SWB)
Stadtwerke Bonn stands for a common German pattern: energy, water and local transport under one municipal roof. This page explains the cross-subsidy model and its consequences.
Typical vehicles
NGT8D
The NGT8D is an eight-axle low-floor articulated railcar from the first German low-floor generation. The type designation tells you more than any spec sheet.
ClassNGT6D / MGT6D
NGT6D and MGT6D are six-axle low-floor articulated railcars of the first generation. The axle count in the name is also the quickest identification feature in the field.
ClassTW 2000
The TW 2000 is Hanover's silver light rail car: unpainted aluminium body, strikingly round front. And the car number tells you the type straight away.
ClassBombardier Flexity Berlin (GT6-12 ZRL)
The Flexity Berlin is BVG's modern low-floor tram. The type code GT6-12 ZRL reveals almost everything – once you know how to read it.
ClassBombardier NGT6DD (Dresden)
The NGT6DD is the short low-floor tram of the Dresdner Verkehrsbetriebe. The type code reveals body type, size and city – once you know how to read it.
ClassTatra KT4D
The Tatra KT4D is the six-axle short articulated tram built in Czechoslovakia that shaped the look of many East German tram networks for decades.
Where you will find Hanning & Kahl
Spotting locations where you will regularly come across vehicles from this organisation – with viewpoints, the best light and coordinates.
Leipzig Hauptbahnhof
Leipzig Hauptbahnhof is Europe's largest terminus station by floor area: 24 platform tracks, a roughly 300-metre-long transverse platform, and two historically separate station halves under one roof. Add to that the City Tunnel below. The spot is productive – but the walking distances are its biggest problem.
Junction stationDresden Hauptbahnhof
Dresden Hauptbahnhof combines two terminal platform halls with elevated through tracks in between - and over it all lies a membrane roof that diffuses daylight evenly instead of breaking it into hard stripes. Add to that the Elbe valley line towards the Czech Republic: eastern Germany's most interesting international connection.
More companies
Kiepe Electric
Kiepe Electric of Düsseldorf doesn't build complete vehicles, but what moves them: traction equipment, inverters and control systems. The company belongs to the Knorr-Bremse group and is as present in trolleybuses as it is in trams.
ManufacturerHeiterBlick
HeiterBlick is one of the few German tram builders outside the big groups. The Leipzig-based company usually delivers in consortium with an electrical partner – which is why the same tram gets attributed to a different manufacturer depending on the source.
ManufacturerKnorr-Bremse
Knorr-Bremse is the rare case of a supplier whose name appears on almost every freight wagon in Europe. The code KE in the brake marking stands for Knorr-Einheitsbremse (Knorr standard brake) – and anyone who can read the marking also reads the brake setting, brake weight and often the approximate build year.
ManufacturerVossloh
In spotting logs, Vossloh stands for a whole family of diesel locomotives – and today builds not a single one any more. The company has long since shifted to rail fastening, points and rail machining. The G-locos keep running regardless, under new owners.
