Key takeaways
- KE stands for Knorr-Einheitsbremse. The code in the brake marking of almost every freight wagon points directly to this manufacturer.
- Hik means Hildebrand-Knorr and is a reliable sign of an older wagon.
- G, P and R are brake settings, not categories: slow-acting for freight trains, fast for passenger trains, R for high speeds.
- The brake weight in the marking describes the braking effect in tonnes and has nothing to do with the payload.
- The group supplies far more than brakes – doors, climate control and, via Kiepe Electric, local transport traction technology too.

How to recognise Knorr-Bremse
Does the train really belong to Knorr-Bremse?
- Brake marking starting with KE – the Knorr standard brake, standard on almost every modern freight wagon
- Hik in the marking – Hildebrand-Knorr, a reliable sign of an older wagon
- Letters G, P and R after the type – the brake setting, i.e. freight, passenger or rapid braking
- Changeover lever on the bodywork with the settings G and P – manually operated, clearly visible
- Brake weight in tonnes after the setting – not the payload, but the braking effect
- Brake cylinder and linkage under the wagon floor – openly visible on freight wagons
- Door manufacturer's plate on the door edge of many multiple units – often the only legible supplier information
Strengths and weaknesses
What the company stands for
- One of the few suppliers whose code really does appear on the vehicle
- Brake markings are easy to read and rewarding to photograph on stationary freight wagons
- The type and setting let you estimate a wagon's approximate age
- The knowledge applies across Europe, not just in Germany
- Brake markings rarely change – features once learned stay valid for a long time
Where it falls short
- The marking names the design, not necessarily the actual supplier of the component
- On multiple units, the braking technology is largely enclosed and not visible
- There are no reliable public figures on market share or unit numbers per class
- Old markings get overpainted or replaced during conversions
- The group is so broadly positioned that individual products can hardly be attributed
Updated: August 2026 – Almost all suppliers to the railway industry are invisible. Knorr-Bremse is the great exception: its name has appeared in abbreviated form on practically every freight wagon in Europe, every day, for decades. You just need to know that the code KE in the brake marking means “Knorr-Einheitsbremse” – Knorr standard brake.
Read markings instead of guessing
Brake type, setting, brake weight – with Traintrack you record what's really written on a wagon.
A supplier whose name is on millions of wagons
The compressed-air brake is the invention that made long trains possible in the first place. Without it, every wagon has to be braked individually; with it, the whole train consist brakes on a single command. What matters is not the brake itself, but the control valve, which turns a pressure change in the main air line into a braking force.
It’s exactly in this field that the company, founded in Berlin in 1905, built its position. Across several generations of designs this became a European standard: first the Kunze-Knorr brake, then the Hildebrand-Knorr brake, and finally the Knorr-Einheitsbremse, whose code KE still appears in almost every brake marking today.
Today the group is a systems house headquartered in Munich with two divisions: rail vehicles and commercial vehicles. Through subsidiaries such as Kiepe Electric, the portfolio reaches far beyond the brake.
Reading the brake marking – learned in three minutes
On the side of every freight wagon there’s a short sequence of characters that looks like technical gibberish and is in fact very orderly. It consists of type, brake setting and brake weight.
| Component | Example value | What it tells you |
|---|---|---|
| Brake type | KE | Knorr-Einheitsbremse – the modern standard design |
| Brake type | Hik | Hildebrand-Knorr – older design, indicates an old wagon |
| Brake setting | G | slow-acting, for long freight trains |
| Brake setting | P | faster-acting, for shorter or faster trains |
| Brake setting | R | increased braking force for high speeds |
| Brake weight | a figure in tonnes | the braking effect, not the payload |
The practical benefit: a wagon with Hik is highly likely to be considerably older than one with KE. A wagon with R setting runs in fast trains, often in combined transport. And a changeover lever with the settings G and P on the bodywork shows you that here it’s decided manually which train the wagon runs in.
The changeover lever is worth a photo
The lever with the settings G and P sits clearly visible on the side of the bodywork or on the underframe. It's one of the few controls you can see completely on a stationary wagon – and it explains at a glance why freight trains brake differently from passenger trains. Further markings are explained in the article on freight wagon types.
Why a freight train takes so long to brake
Brake setting G is not a weakness, but intent. In a 600-metre train, the pressure change in the main air line measurably takes time to reach the rear. If the front wagons braked at full force immediately, the rear ones would run into them – with considerable longitudinal forces within the train consist.
That’s why the brake in setting G builds its force deliberately slowly. The price is a considerably longer braking distance. From this follows the most important safety rule for spotters: a freight train can’t swerve and practically can’t stop in time. The braking distance is many times the sight distance at a typical photo spot.
Passenger trains run in setting P or R and brake correspondingly harder. On modern multiple units, electric braking is added, largely relieving the mechanical part – one reason why, on vehicles like the ICE 4 or the Stadler FLIRT, there’s barely anything to see of the brake from outside.
Wagon markings are a collecting field of their own
Type, category, keeper, brake weight: with Traintrack, a detail photo becomes a searchable entry.
How to read a freight wagon from bottom to top
Find the brake marking
It sits on the side of the bodywork or on the underframe, usually near the data panel with the vehicle number.
Determine the type
KE means Knorr-Einheitsbremse, Hik the older Hildebrand-Knorr design. That alone gives you a rough time frame.
Read the setting
G, P or R. It tells you what kind of train this wagon normally runs in and how it brakes.
Note the brake weight
The figure in tonnes describes the braking effect. It's decisive for the permitted speed of the whole train.
Add the vehicle number
Only the twelve-digit number makes the wagon unambiguous. The brake marking is context, not identity.
How much is in your wagon note?
Type and number together give you technology and identity – the rest is fine detail.
More than brakes: doors, climate control, traction technology
Anyone who thinks of the group only in terms of the brake underestimates it. Through subsidiaries it covers further systems that are quite visible to spotters.
Door systems frequently come from the subsidiary IFE and carry a small manufacturer’s plate on the door edge – one of the few supplier markings you actually read in everyday life, because you’re standing right in front of it when boarding. Climate control sits as roof equipment on passenger coaches and multiple units and noticeably shapes their roof silhouette.
And since 2017, via Kiepe Electric, traction technology for trams, light rail and trolleybuses has been added. So group technology sits not only in the freight train, but also in the tram outside your front door – for instance in the TW 3000 in Hanover.
When the marking really proves something
Reliable statement, if …
- you've fully read the brake marking
- type, setting and brake weight fit together
- you've also noted the vehicle number
Be cautious, if …
- the wagon has visibly been converted or newly marked
- the marking is partly overpainted or weathered
- you want to infer the actual component supplier from the brake code
No statement, if …
- you've only seen the wagon shape
- the wagon was photographed from a distance and nothing is legible
- you confuse the brake weight with the payload
One important caveat belongs here: the brake marking names a design, not necessarily a supplier. KE is a standardised design that other manufacturers can also produce under licence or to the standard. The name stands there as a type designation – historically founded, but no proof of the contents of every individual valve.
Never photograph between parked wagons
Parked freight wagons look harmless and aren't: they can be moved at any time, often shunted and without warning. Never enter track areas to reach a marking, and never crawl under or between wagons. What applies is set out in the articles on trespassing on tracks and on safety distance at the track.
Verdict
Knorr-Bremse is proof that supplier knowledge can be practically useful for spotters. No other name in the railway industry appears so systematically on the vehicle – and no other marking reveals so much about a wagon’s technology and age for so little effort.
Anyone who can read the brake marking no longer sees a row of brown boxes on a parked freight train, but a timeline. Old designs next to new ones, different brake settings, different brake weights. It costs three minutes of learning and lasts a spotter’s whole life.
Quick verdict
A world market leader in braking systems whose code KE appears on almost every freight wagon. The marking reveals type, brake setting and brake weight – the wagon's identity is still supplied by the vehicle number.
Read the train, not just the locomotive
Wagon markings are the most underrated collecting field there is. Traintrack makes them searchable.
Summary
- Brake markings are the one place where a supplier's name systematically appears on the vehicle – and they're surprisingly easy to read.
- Anyone who can recognise the type and setting can roughly date a freight wagon without knowing its running number.
- The group has long been a systems house: brake, door, climate and, through a subsidiary, local transport traction technology too.
- For the sighting itself, the running number remains decisive – the brake marking is context, not identity.
Frequently asked questions
What does KE mean on a freight wagon?
KE stands for Knorr-Einheitsbremse, the brake design that has been the European standard in freight traffic since the post-war decades. It appears in the brake marking on the side of the wagon, usually together with the brake setting and brake weight. It's one of the few examples where a supplier's name is permanently marked on the vehicle.
What do the letters G, P and R mean?
They denote the brake setting. G is the slow-acting freight-train braking that prevents a long train from bunching up under braking. P acts faster and is used for shorter or faster trains. R stands for increased braking force at high speeds. Many freight wagons have a changeover lever used to switch between G and P.
What is the brake weight?
A calculated figure in tonnes describing how strongly a vehicle brakes – not how heavy it is. The sum of a train's brake weights and its total mass determine the permitted speed and the gradient it may run on. That's why the value sits right next to the brake type. Further markings are explained in the article on freight wagon types.
How do I recognise an old freight wagon by its brake?
By the code Hik instead of KE. The Hildebrand-Knorr brake is the older design and is now found only on wagons that have been in the fleet a long time. Exposed brake linkage, block brakes instead of disc brakes, and manually operated changeover levers are also age indicators. A look under the wagon floor gives you the approximate decade.
Does Knorr-Bremse also build locomotives?
No. The group is a systems supplier and delivers brakes, doors, climate control and control systems to vehicle manufacturers. Complete vehicles are built by firms such as Siemens Mobility, Alstom or Stadler Rail. Their products, such as the Siemens Vectron, contain supplied components from several houses.
What does Kiepe Electric have to do with Knorr-Bremse?
Kiepe Electric has belonged to the group since 2017. Before that, the Düsseldorf company traded as Vossloh Kiepe. It supplies electrical equipment for trams, light rail and trolleybuses. That means the group covers local transport traction technology as well as the brake.
Can you see the braking technology on multiple units too?
Considerably less so. Modern multiple units enclose their technology, and disc brakes sit on the axle shafts within the bogie. Brake markings still exist, they're just smaller and less prominently placed. On vehicles like the Stadler FLIRT or the ICE 4 you'll need platform height and patience for that.
Where can I photograph brake markings well?
On parked freight wagons, so at freight hubs and marshalling yards. At Maschen, Hagen-Vorhalle or Hamm (Westphalia) wagons often stand for long periods. The location matters: only from the platform or from public paths.
Why does a freight train brake so slowly?
Because it's running in setting G. The brake pressure builds deliberately slowly so that braking force acts more evenly from front to back and the train doesn't run into itself. In a 600-metre train, the pressure wave noticeably takes time. That's exactly why braking distances in freight traffic are many times longer than for passenger trains.
Is Knorr-Bremse relevant for a sighting?
As context yes, as identity no. A sighting becomes unambiguous through vehicle number, keeper and lead railway operator. The brake marking tells you something about the wagon's technology and age and is an excellent addition – but it doesn't replace the number. How to read it is in the guide to the UIC number.

The operational level in the railway operator database
Who actually runs the trains, with keeper markings and identifying features on the vehicle.
DB Cargo Deutschland AG
DB Cargo is Deutsche Bahn's freight division and Germany's largest freight railway. You can spot it straight away by the keeper marking D-DB and its traffic-red livery.
Long-distanceDB Fernverkehr AG
DB Fernverkehr operates the long-distance passenger services of Deutsche Bahn. Service category, train type and data panel quickly lead you to the right classification.
Local & regionalDB Regio AG
DB Regio is Deutsche Bahn's local rail division. The group organises regional services regionally – which is why the brand on the train and the keeper marking on the vehicle often don't match.
Typical vehicles
Siemens Vectron
The Vectron is Siemens's modular locomotive platform and shapes European freight services. Here's how to identify the variants and read the number correctly.
ClassBombardier TRAXX
TRAXX isn't a single class but a platform: the same base locomotive in many variants. Here's how to decode the type designations and identify the family.
ClassDB Class 412 (ICE 4)
The Class 412 is the ICE 4: a multiple unit with powered powercars that runs to seven, twelve or thirteen cars depending on the variant. Here's how to identify it reliably.
ClassStadler FLIRT
The FLIRT is Stadler's most widespread regional multiple unit in Germany. Class 427, 428 or 429 – the number tells you straight away how many cars the train has.
ClassDB Class 101
The Class 101 is Deutsche Bahn's classic long-distance locomotive: 145 engines, 220 km/h, in front of IC and EC trains since the late 1990s. Here's how to reliably recognise it.
ClassClass 1440 (Alstom Coradia Continental)
The Class 1440 is the younger generation of the Alstom Coradia Continental. Its four-digit number reveals a lot about the German class numbering system – and about the train itself.
Where you will find Knorr-Bremse
Spotting locations where you will regularly come across vehicles from this organisation – with viewpoints, the best light and coordinates.
Rangierbahnhof Maschen
The Maschen marshalling yard south of Hamburg is the largest facility of its kind in Europe: two complete hump yards, two humps, around seven kilometres in length. It can only be observed from public road bridges – the operational site itself is off limits and stays that way.
Junction stationHamm (Westf) Hauptbahnhof
At Hamm, the Ruhr region's great routes go their separate ways: towards Hanover, towards Münster and towards Kassel. Add to that a freight share that hardly any other German main station of this size reaches – and a platform hall that ties the whole operation together.
Freight hubHagen-Vorhalle Marshalling Yard
Hagen-Vorhalle is one of Germany's large marshalling yards, sitting at the northern end of the Ruhr-Sieg line. Observation is strictly from public roads and bridges – accept that, and you get to see operations that modern freight hubs no longer show.
Junction stationKöln Hauptbahnhof
Few stations in Europe pack so much traffic into so little space: over 1,200 train movements a day, eleven platform tracks, and the Hohenzollern Bridge starting right behind the platform ends. Get Köln Hbf right, and you'll have more in the bag after two hours than elsewhere in a whole day.
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.
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.
ManufacturerVoith Turbo
Voith Turbo is first and foremost drive technology: turbo transmissions, couplings, components. For a good decade, though, the company was also a locomotive builder – and that's exactly where the Gravita and Maxima come from, which you still encounter in shunting and freight service today.
ManufacturerSiemens Mobility
Siemens Mobility doesn't build individual vehicles, it builds platforms: a Vectron in Sweden and one in Slovenia are the same machine with different equipment. Anyone who understands the platform logic can recognise the vehicles even when the livery gives nothing away.
