Key takeaways
- English long forms like "Rail Transport Service" describe a service, not a fixed traffic segment.
- Orange placards mark dangerous goods – they belong to the load, not the wagon.
- Hazard labels are diamonds with a symbol and a number, and state the type of hazard.
- Markings are no reason to get closer: for dangerous goods trains, keeping your distance applies without exception.
- Three-letter codes are standard in freight traffic – and the most common source of confusion.

How to recognise this operator
Is this really RTS Rail Transport Service?
- Code RTS with an English long form in the company name
- "Transport" and "Service" point to freight traffic and a service business
- No regional reference in the name – the area of operation can't be inferred from it
- Wagons in the train carry their own markings, independent of the operator
- Dangerous goods wagons are recognisable by orange placards and hazard labels
Updated: August 2026 – RTS Rail Transport Service is one of those company names that combines a code with an English long form. This page shows what can be inferred from that – and then explains a detail visible on many freight trains that’s still often read wrongly: the marking of dangerous goods on the wagon.

What is RTS Rail Transport Service?
RTS Rail Transport Service is a German railway company whose company name is made up of a code and its English long form. All three words are activity descriptions: “Rail” names the mode of transport, “Transport” the service, “Service” the service character. Together, that gives a clear placement in freight traffic, but no statement about traffic type, region or size.
English company names have long been common in the European rail market, because they stay understandable across borders. For identification in the field, that changes nothing: the data panel on the vehicle is what matters.
Three letters, many companies
Three-letter codes are standard in freight traffic – and the most common source of error in sightings. Always note the full company name exactly as it appears in the source, and keep it clearly separate from the keeper marking in the data panel. Both are different pieces of information with different meanings.
Dangerous goods marking: what becomes visible on the wagon
Anyone who regularly watches freight trains knows the orange placards. They’re neither decoration nor a wagon number, but part of a Europe-wide standard marking system for dangerous goods.
Orange placard
A rectangle split in two with two number sequences. The top one gives the hazard description, the bottom one the number that uniquely identifies the substance.
Hazard label
Diamond-shaped panels with a symbol, colour and number. They show the type of hazard – for example flammable, corrosive or environmentally hazardous.
Position on the wagon
They're fitted so as to stay visible from both sides. On tank wagons, they usually sit on the side of the tank or on the frame.
Relation to the load
The marking describes the current load, not the wagon. After unloading and cleaning it can be removed or covered.
A marking is no reason to get closer
Placards and labels can be read from a distance with a telephoto lens. Approaching a train to decipher them is dangerous and prohibited in operational areas. In the event of an incident involving dangerous goods, the same rule applies regardless: keep your distance, follow the instructions of emergency crews, and don't document anything that gets in the way of their work. The basics are covered in the guide Safe distance at the track.
What you should be able to tell apart
| Marking | Shape and colour | States | Applies to |
|---|---|---|---|
| Orange placard | Rectangle, orange, two number blocks | Hazard and substance identity | the current load |
| Hazard label | Diamond with symbol and number | Type of hazard | the current load |
| Data panel | Number block with keeper marking | Identity and keeper | the wagon, permanently |
| Load limit diagram | Rectangle with several rows | Permitted load by line category | the wagon, permanently |
| Inspection marking | Text with place and date | Maintenance status | the wagon, permanently |
That distinction is the real takeaway here: two of the markings change with every run, three stay the same for years. Anyone who notes both together with a date can classify a sighting properly later. How the number block itself is built is explained in the guide to the UIC number on the vehicle.
Record the details without getting closer
Note the wagon type, marking and date – Traintrack sorts your observations automatically.
Vehicles and where they fit in the network
Ahead of freight trains with high hauled loads, heavy machines such as the Class 152 run in electric mainline service; on non-electrified sections, powerful diesel locomotives such as the Class 241 or the four-axle Vossloh G 2000 BB. These are statements about common types on the German network, not about the fleet of any particular company.
In the same market segment you’ll come across companies such as Raildox and RTB Cargo, plus the market leader DB Cargo. Which operators actually run on a given route is best shown by your own observation over several days – the overview in the freight train radar also helps.
Reading markings in a train formation
A train carrying dangerous goods is rarely marked consistently throughout. Marked and unmarked wagons often run in the same formation, because they carry different loads or because individual wagons are empty and cleaned.
For observers, a simple rule follows: markings apply wagon by wagon, never to the whole train. Anyone who notes “saw a dangerous goods train” loses exactly this distinction. It’s more useful to note that individual wagons were marked – with date, place and, where you can tell, the type of wagon.
Second, it’s worth looking at the train formation. For trains carrying particular loads, there are rules that affect the order and composition. From outside, only the result is visible, not the rule behind it. Here too: document, don’t interpret.
And third, markings change several times over the course of a wagon’s rotation. The same tank wagon from a lessor such as VTG can be marked today and unmarked in two weeks. That’s exactly why the timestamp matters more for such sightings than for any other.
English company names in the German rail market
Company names like “Rail Transport Service” look international at first glance. In fact, they say little about a company’s origin. English names have become established in the European rail market for practical reasons: they’re understandable across borders, shorter than German compound words, and easier to fit onto a vehicle.
That gives a useful rule of thumb for reading names. The English part usually describes the activity or role: “Cargo”, “Logistics”, “Transport”, “Service”, “Carrier”, “Rail”. The non-English part – code, place name, personal name – describes origin or identity and is usually the part that doesn’t explain itself.
In practice, that means: read the descriptive words first, because they’re reliable. Everything else takes research. And even once you fully understand the name, identifying a specific vehicle remains a separate task – for that, the data panel is and remains the only reliable source.
Common mix-ups
- Tank wagon equals dangerous goods – type of wagon and load are two different things.
- Placard belongs to the wagon – it actually belongs to the load and changes with it.
- RTS, RST, RTB – similar codes, different companies. Always note the long form.
- English name equals a foreign company – English company names are normal in the German market.
- No marking equals empty – even loaded wagons don’t always carry an orange placard.
Verdict
The name RTS Rail Transport Service describes a rail transport service – no more, but no less either. Anyone watching such trains gains the most by clearly separating the markings on the wagon: what describes today’s load, and what describes the wagon over the years?
In short
Code plus English long form says: freight traffic, nothing more. On the wagon, though, there's a lot to read – you just need to know what changes with every run and what stays. And with dangerous goods, without exception: keep your distance.
Summary
- RTS Rail Transport Service places itself in freight traffic through its name components.
- Dangerous goods markings follow a fixed, Europe-wide standard layout and can be read from a distance.
- The marking describes the current load – it can change with every run.
- Only ever observe from publicly accessible locations and keep your distance from the track.
Frequently asked questions
What does the name Rail Transport Service say?
It describes a service around rail transport. "Rail" names the mode, "Transport" the activity, "Service" the service character. The name doesn't fix a traffic segment in the narrower sense – block train, single wagonload, combined transport – and it doesn't fix an area of operation either.
What does the orange placard on the wagon mean?
It marks a consignment of dangerous goods. The upper number sequence describes the type of hazard, the lower one identifies the substance. Important for understanding: the placard belongs to the load, not the wagon – the same tank wagon can carry a different marking on its next run.
What are hazard labels?
Diamond-shaped stickers or panels with a symbol, colour and a number. They name the type of hazard, for example flammable, corrosive or toxic. They usually sit next to or below the orange placard. They too refer to the load currently being carried.
Am I allowed to photograph dangerous goods trains?
From a publicly accessible location, the same rules apply as for any other train. What's not allowed: getting closer to the track to decipher placards, or entering operational railway land. Keep your distance, use a telephoto lens, and don't get in anyone's way – when in doubt, follow instructions from staff on site.
Are tank wagons always dangerous goods wagons?
No. Tank wagons also carry harmless liquids and bulk goods. Conversely, dangerous goods also travel in covered wagons, containers and tank containers. So the type of wagon says nothing about how hazardous the load is – the marking does.
Why does the same wagon sometimes carry a placard and sometimes not?
Because the marking is tied to the load. An empty, uncleaned wagon can still be marked, while a cleaned one isn't. For sightings, that means: note the marking with a date, otherwise the observation can't be classified later.
How do I tell RTS apart from similar codes?
Via the full company name. In German freight traffic there are numerous three-letter codes that differ only in the order of the letters. Anyone who only notes "RTS" risks a wrong identification – write down the long form too, exactly as it appears in the source.
Which vehicles are typical for such traffic?
Powerful electric and diesel locomotives on the mainline run, compact shunting machines for local delivery. Dangerous goods traffic adds stricter requirements for brakes, train formation and staff qualification – practically none of that is visible from outside.
