Key takeaways
- RegioTram is a system name, not a company. The brand belongs to the transport association; operating companies do the actual running.
- One vehicle, two rulebooks. Tramway law applies in the city, railway law on the line – with consequences for licensing and staff.
- The system changeover is the core of the concept. At defined points, the electrification system and the operating regime both switch.
- Some branches aren't electrified. For those there are vehicles with an additional diesel drive – a rare design.
- Identify the section of the route first, then the vehicle. Without this step, the sighting can't be classified cleanly.

How to recognise RegioTram Kassel
Does the train really belong to RegioTram Kassel?
- Light rail vehicles on railway tracks – the most striking and reliable feature
- Two pantograph positions, or system changeover at defined points
- Diesel unit on vehicles for non-electrified branches – audible and visible
- Low platform edges in the city, higher ones at railway stations
- RT line codes instead of a classic train category
- Association logo rather than an operator logo as the dominant marking on the vehicle
Strengths and weaknesses
What the company stands for
- A vehicle type that exists in this form in only a handful of places in Germany
- System changeover points make an unusual and well-documentable subject
- Urban and railway subjects can be combined in a single day
- The network is compact enough to cover in a weekend
- Comparison with other dual-system cities makes the concept easier to grasp
Where it falls short
- The brand belongs to the association, not the operator – so identification is correspondingly tricky
- Two rulebooks mean two authorities and confusing lines of responsibility
- Operations and contract arrangements have changed several times
- The fleet is small, so the variety of subjects is correspondingly limited
- No dedicated spot pages for Kassel have been added here so far
Updated: August 2026 – A vehicle that stands among cars at a stop in the middle of the city and, twenty minutes later, runs on a railway line out in the countryside: RegioTram Kassel fits none of the usual categories. And because the brand belongs not to the operator but to the commissioning transport association, the question of which company runs it is especially tangled here too.
Classify dual-system vehicles properly
Tram or railway? Note the section, number and date, and the sighting stays unambiguous.
Two worlds, one vehicle
Trams and railways are two separate legal worlds in Germany. They differ in the construction and operating regulations that apply, in oversight, in the training of on-board staff, in signalling systems and in vehicle approval. A normal tram may not run onto a railway line, and a normal railcar may not run into a pedestrian zone.
Dual-system concepts like this one bridge exactly that divide. The vehicle meets both sets of requirements at once: it’s strong enough for railway operation, narrow and manoeuvrable enough for urban traffic, handles two electrification systems and is approved under two rulebooks. This dual approval is expensive and demanding – the payoff is that passengers can get from the region into the city centre without changing.
Who actually runs RegioTram?
This is where it gets unusual. The brand belongs to the commissioning transport association – which is why the official web address leads to its presence, not to a transport company. For the railway part, a dedicated operating company was created in the form of RegioTram Gesellschaft mbH; on the urban network, the Kasseler Verkehrsgesellschaft is responsible.
Responsibilities and operations have been reorganised several times over the years, without much visibly changing for passengers. A day-to-day split is therefore deliberately not given here – anyone who needs to know it for a specific day should check the timetable information or read it off the vehicle itself. In the wider surrounding area you’ll also encounter cantus, DB Regio and companies from the Hessische Landesbahn group.
Note the section before the vehicle
With dual-system vehicles, the section of the route decides whether you're looking at a tram sighting or a railway sighting. So write it down first. The same vehicle in two places can justify two separate entries in a cleanly kept collection.
How to spot RegioTram in the field
Check the surroundings
Street space and low stop edges mean the tram network; railway platforms and signals mean a railway line.
Look at the vehicle shape
A light rail vehicle on a railway track is the clearest sign of the concept. The reverse holds equally.
Listen to the drive
If a diesel unit is running, you're on a non-electrified branch. That's a rare and documentation-worthy sight.
Note the line number
The RT code assigns the journey to the dual-system network and sets it apart from regular tram and regional lines.
Record the vehicle number
As with any other sighting, it's the one piece of information that outlasts contracts, brands and changes of responsibility.
Tram, railway, dual-system
| Criterion | Classic tram | Dual-system vehicle | Classic regional train |
|---|---|---|---|
| Rulebook | tramway law | both, depending on the section | railway law |
| Infrastructure | urban network | urban and railway network | railway network |
| Electrification system | one DC system | two systems, some plus diesel | one AC system |
| Platform height | low | can serve both heights | high |
| On-board staff | tram training | dual qualification | railway training |
| How to classify the sighting | tram | depends on the section | railway |
The last row is what matters for collectors. Anyone who strictly separates tram and railway sightings has to make a conscious decision with dual-system vehicles – and that decision should be documented in the logbook so it stays traceable later. The conceptual groundwork for this is laid out in the article Stadtbahn or tram.
Why such systems have stayed rare
The idea is appealing: link two existing networks, save on new-build lines, and bring passengers into the centre without a change. In practice, though, the effort is considerable. Vehicles need dual approval, staff need dual qualification, platform heights have to match up or the vehicle has to be able to serve both, and every system changeover point needs its own technical and operational solution.
Then there’s the question of responsibility. Two rulebooks mean two supervisory authorities, two approval procedures and two safety regimes. Add several transport authorities, a transport association, a municipal transport company and a dedicated operating company all involved, and the result is a web that’s barely possible to see through fully from the outside. That’s exactly why only a handful of such systems were ever built in Germany – and why the question of the operator is so much harder to answer here than for an ordinary regional railway. For spotters, that’s no drawback: what’s rare is all the more worth the trip.
Tram and railway in one collection
Traintrack keeps both worlds in one logbook – with a clear split where it's needed.
Is a dual-system trip worth it?
What are you planning?
Planning aid for a small network – the choice of subjects counts here more than the number of trains.
Tram sighting or railway sighting?
Log it as a railway sighting when …
- the vehicle is running on a railway line
- railway signals and platforms shape the location
- the journey takes place outside the urban network
Note both when …
- you catch the vehicle at the system changeover point
- the journey links both networks in a single diagram
- you photograph the same vehicle in both settings
Log it as a tram sighting when …
- the vehicle is running in the street space
- low stop edges and road traffic define the scene
- the journey never leaves the urban network
No dedicated spot pages for Kassel itself have been added here so far. Anyone looking for locations will find pointers in the regional guides to Kassel and to Hesse; for the tram side, it’s worth checking the Hesse tram guide.
Different rules apply in the street space
On the tram section, you're standing in public traffic space: watch out for cycle lanes, the carriageway and other road users, not just the track. On the railway section, the usual rules apply instead – see safe distance from the track and trespassing on tracks.
Verdict
RegioTram is the rare case where the question “who actually runs this?” asks not only about the company but about the rulebook too. The brand belongs to the association, operations have been reorganised several times, and the vehicle switches between two legal worlds while the passenger only experiences one continuous journey.
For your collection that means: note first where you were, then what you saw. With section, number and date, the sighting stays unambiguous – regardless of how responsibilities are divided up in the next contract.
Quick verdict
A system name that belongs to the transport association, and a vehicle that shuttles between two rulebooks. Identify the section of the route first, then the vehicle.
Record where the vehicle actually was
With dual-system vehicles, the location is part of the sighting. With Traintrack you capture both in one step.
Summary
- Dual-system services break the usual categories: they're neither a pure tram nor a pure railway.
- Because the brand belongs to the association, it says even less about the operator than an ordinary transport brand would.
- The practical appeal lies in the system changeover points and the vehicles with an additional diesel drive.
- Anyone documenting here should always note the section of the route, because it decides which rulebook applies.
Frequently asked questions
Is RegioTram a tram or a railway?
Both, depending on the section of the route. In the city it runs on the tram network and falls under tramway law; outside the city it uses railway lines and falls under railway law. This dual nature is exactly the core of the concept – and the reason the service can't be filed into either of the two usual boxes. The article Stadtbahn or tram? sorts out the terminology in general.
Who operates RegioTram?
For the railway part, a dedicated operating company was created in the form of RegioTram Gesellschaft mbH; on the urban network, the Kasseler Verkehrsgesellschaft operates the infrastructure. Responsibilities and operations have been reorganised several times over the years, which is why no day-to-day split is given here deliberately. The current timetable is always the reliable source.
Why does the website belong to the transport association?
Because the brand belongs to the commissioning authority and not to the operator. The association commissions the service, sets the fares and appearance, and markets the offer under its own name. That's the normal case in German local transport, but it's especially clear here: the operator practically never appears in public communication.
Which vehicles run there?
Dual-system light rail vehicles licensed for both networks – classed as Class 689/690. Some of the vehicles also have an additional diesel drive to reach branches without an overhead line. This combination of a light rail vehicle, dual-system technology and a diesel unit is extremely rare in Germany.
What happens at a system changeover point?
There, the vehicle switches between the two networks and thereby between two electrification systems and two operating regimes. The transition happens at fixed, defined points and is noticeable even to passengers. For spotters, this is the most interesting point in the whole network, because it shows in a single shot exactly what the concept is about.
Are there similar systems in Germany?
Yes, several cities have implemented dual-system concepts, including the Saarbahn and the Stadtbahn Heilbronn. The technical solutions differ in detail, but the underlying problem is the same everywhere: two rulebooks have to be brought together in one vehicle. A comparison is worthwhile because it shows how differently the same task can be solved.
Why do some vehicles have a diesel engine?
Because not all the railway branches in the surrounding area are electrified. Rather than electrifying them at great expense, some vehicles were fitted with an additional drive that takes over on these sections. For you on the platform, this is a clearly audible feature – a light rail vehicle that suddenly sounds like a diesel railcar.
Who else runs services in North Hesse?
In the wider region you'll encounter operators including cantus, DB Regio and companies from the Hessische Landesbahn group. At the railway stations in the surrounding area, light rail vehicles and classic regional railcars therefore meet directly – a contrast that explains the concept better than any description.
Where are the good photo spots?
No dedicated spot pages for Kassel have been added here so far; that's a gap in the database. The nearest fully documented hub in Hesse is Frankfurt Hauptbahnhof. For Kassel itself, the regional guides to Kassel and to tram photography in Hesse help further.
How do I note down a RegioTram sighting?
First the section of the route, because it decides whether you're documenting a tram or a railway sighting. Then the vehicle number, line, place and date. This order matters more with dual-system vehicles than elsewhere – how to read the number correctly is explained in the article on 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.
RegioTram Gesellschaft mbH (RTG)
The name RegioTram stands for an operating model: vehicles that run through the city network like a tram and on the railway line like a local train. Here's how to spot that in the field.
Local & regionalKasseler Verkehrsgesellschaft
The Kasseler Verkehrsgesellschaft stands for urban local transport in northern Hesse. One theme shapes its operations more than you'd think: winter.
Local & regionalCantus Verkehrsgesellschaft mbH
Cantus Verkehrsgesellschaft mbH is a railway operator in local services. Its invented name reveals nothing about the region – you have to identify it from the vehicle and train working.
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.
Local & regionalHessische Landesbahn GmbH
Hessische Landesbahn runs regional services. But its trains often carry transport-association colours – so you need to identify the company by other features.
Typical vehicles
Class 689 / 690
The designation Class 689 / 690 groups two neighbouring number ranges in the railcar block. Here's how to read the number and place it correctly.
ClassSaarbahn Class 0450 (Bombardier Flexity Link)
The Saarbahn's Bombardier Flexity Link is tram and railway vehicle at once. As Class 0450 it carries a genuine railway vehicle number – here's how to recognise it.
ClassClass 427 (Stadler FLIRT)
Class 427 is the three-part Stadler FLIRT in German regional service. Car count, Jakobs bogies and the vehicle number get you to the right answer in seconds.

More companies
Saarbahn
Saarbahn is a brand name for a dual-system light rail network that starts in the street space of Saarbrücken and continues on railway tracks all the way to France. Halfway along, the vehicle changes voltage, rulebook and jurisdiction – without passengers noticing a thing.
BrandStadtbahn Heilbronn
Stadtbahn Heilbronn is a service brand with no railway undertaking of its own. It's run by a Karlsruhe company, the city-centre tracks belong to the city of Heilbronn, and the dual-system technology comes from a model developed elsewhere.
GroupHessische Landesbahn (HLB)
The Hessische Landesbahn is a group of several companies: one for passenger services, one for freight, one for its own infrastructure. The train usually just says HLB or a brand name – you only find out the operating company from the data panel.
GroupDeutsche Bahn AG
Deutsche Bahn AG doesn't run a single train itself. It's a holding company under which dozens of independent companies hold their own licences, rolling stock and transport contracts. Spotting the red DB logo doesn't tell you the operator.
