Key takeaways
- The Metro is not a railway operation and doesn't belong to the Danish state railway.
- Owner and operator are separate: a public company owns the system, a contracted company runs it.
- Driverless and round-the-clock operation are two features that set the system apart from the S-tog and main-line rail.
- Conductor rail instead of overhead line is the fastest visual way to tell it apart in Copenhagen.
- Three systems, three electrification types: the Metro, S-tog and main-line rail each have their own technology in this city.

How to recognise Metro Kopenhagen
Does the train really belong to Metro Kopenhagen?
- No driver's cab – front and back have a window with a clear view into the tunnel, no driving console
- Short, narrow trains with a continuous interior – noticeably smaller than S-tog vehicles
- Side-mounted conductor rail instead of overhead line – look up and you'll see no contact wire
- Platform screen doors at the newer stations on the ring line
- Line names starting with M – unlike the lettered lines of the S-tog
- Very short headways, but short train lengths – the reverse principle of a classic suburban railway
- Its own alignment with no network connection – the Metro shares no track with any other railway
Strengths and weaknesses
What the company stands for
- Driverless operation is itself worth seeing as a system, and still not universal in Europe
- Continuous overnight service makes photography possible at times when every other network stands still
- The unobstructed view forward from the train is a subject a classic underground can't offer
- Short distances between Metro, S-tog and main-line rail – three systems in one day
- Clear, well-documented network structure with no historical special cases
Where it falls short
- Not a railway operation – entirely irrelevant for class lists and EVU collections
- Very low vehicle variety with practically uniform rolling stock
- Underground sections are photographically difficult and in places only accessible with restrictions
- Platform screen doors block the view of the vehicles almost completely at many stations
- The split between owning company and operator is barely visible from the outside
Updated: August 2026 – Three rail systems run side by side in Copenhagen that have almost nothing technically in common: main-line rail, the S-tog and Metro Kopenhagen. They differ in electrification system, vehicle size, regulations and operator – and of the three, the Metro is the one that has the least to do with a railway. That’s exactly why it so often ends up in the wrong category in sighting lists.
Three systems, three categories
Log Metro, S-tog and main-line rail separately – then your collection stays cleanly sorted.
Who’s actually running here
The Metro belongs to a public company owned jointly by municipalities and the state. This company owns tunnels, stations, vehicles and system technology – and plans further expansion. What it does not do: run the operation itself. That’s the job of a contracted company from the world of international metro operators and system manufacturers.
This split is standard for modern driverless metros and has a technical reason. A fully automatic system consists of vehicles, signalling and operations-control technology that only work as a coordinated package. Whoever builds it can also operate it – and is therefore often contracted for both at once.
For you on the platform, that means: there’s no visible operator name in the classic sense. What you see is the system brand. Who’s actually driving the train appears nowhere – and in any case, no one is at the controls.
Three systems, three electrification types – how to tell them apart
The quickest way to the right category is via the power supply. The Metro draws its power from a side-mounted conductor rail; there’s no contact wire above the trains. The S-tog runs under overhead line with its own, historically grown DC voltage. Main-line rail in turn uses yet another system.
That lets you decide in seconds which world you’re in – without having to identify a single vehicle.
| Feature | Metro | S-tog | Main-line and regional rail |
|---|---|---|---|
| Power supply | side-mounted conductor rail | overhead line, DC voltage | overhead line, different system voltage |
| Crew | none on board | driver | driver |
| Vehicle size | short and narrow | wide, multi-part | railway vehicles |
| Line designation | M plus digit | letters | train numbers and categories |
| Legal framework | own metro regulations | railway law | railway law |
Look up, not at the train
Looking up at the ceiling, or the sky, answers the system question faster than any vehicle identification: contact wire means S-tog or railway, no contact wire means Metro. This principle works in any city with mixed systems and saves you a lot of guesswork.
What driverless operation means in practice
Without a driver, more changes than just the staffing sums. Headways can become very tight, because spacing is regulated computationally rather than by sight. The trains are correspondingly short – the reverse principle of a classic suburban railway, which runs long trains at wider intervals.
And it makes round-the-clock operation possible. A network that runs 24 hours a day is an unusual situation for observation and photography: you can work at times when every other rail service stands still. Tips on the technique underground are in the piece Underground photography.
The most striking effect, though, concerns the view. Because there’s no driver’s cab, you can sit right at the front, directly against the window. The front perspective from the moving train – an unreachable subject on any railway – is here accessible to every passenger.
A fourth point concerns the stations themselves. Driverless systems are almost always built with platform screen doors, because with no crew on board no one is watching the track area. For passengers that’s a safety gain; for photography, an obstacle: at such stations you can see practically only the interior of the vehicle. If you want to document the trains in full, you need to head for the network’s above-ground sections.
Identify the system
Conductor rail or overhead line? That question decides which category the sighting belongs in.
Note the line designation
M-lines belong to the Metro, lettered lines to the S-tog. Mixing them up is the most common list error.
Use the front perspective
Sit right at the front. The unobstructed view into the tunnel is the subject that makes this system unique.
Head for interchange stations
Only there do two or three systems sit close enough together for the comparison to work in a photo.
Leave the city for railway subjects
You won't find long-distance and freight traffic in the Metro network, but at the country's railway hubs.
Do you have all three systems?
Continuous night operation is something you'll get in hardly any other European capital.
Keep local transport and railway separate
Metro, S-tog, main-line rail: in the Traintrack app, every sighting lands in the right category.
Metro or railway – how to decide in doubt
It's the Metro when …
- the train has no driver's cab and passengers sit at the front
- there's no overhead line above the track
- the line is designated with an M
Look more closely when …
- you're standing at an interchange station with several systems
- platform screen doors block the view of the vehicle
- the section runs above ground and so looks like a suburban railway
If you want to see the railway side of Denmark, you need to leave Copenhagen, or at least head for the Central Station. For Öresund traffic, the Swedish side at Hyllie is worth a look; for freight and long-distance traffic, Fredericia is a better bet. Banedanmark is responsible for the national network – it has nothing to do with the Metro.
House rules apply especially strictly underground
Metro stations are privately managed facilities with high passenger density. Tripods, flash and longer setups are generally not permitted there, and security staff respond more firmly than on an open platform. Follow the instructions on site; the legal framework is summarised under Am I allowed to photograph public transport?.
Conclusion
Metro Kopenhagen isn’t a railway subject, but it’s a very good illustration. It shows how a modern local-transport system is built: ownership and operation kept separate, technology procured as a complete package, network expanded in stages.
In practice, the most important thing is clean categorisation. Metro, S-tog and main-line rail belong in three different drawers – and once you’ve understood this distinction in Copenhagen, you can apply it in any city with mixed systems afterwards. A European overview on this is provided by the piece Tram and local rail networks in Europe.
In short
A driverless metro system in public ownership, run by a contracted company. Not a railway operator, not part of the state railway – and distinguishable from the S-tog and main-line rail in two seconds via the conductor rail.
Keep systems separate, keep collections clean
Note category, line and place – then even a city trip stays analysable.
Summary
- Copenhagen is a textbook example of how "railway" in a city can mean three completely different technical systems.
- If you file the Metro under a railway collection, you're mixing categories – it belongs in the local-transport world.
- Driverless operation delivers a subject other networks don't have: an unobstructed view forward from the moving train.
- For main-line and freight subjects you have to leave Copenhagen and head towards Jutland or the Öresund.
Frequently asked questions
Does Metro Kopenhagen belong to DSB?
No. The Danish state railway DSB operates long-distance services and, via a subsidiary, the S-tog in Copenhagen. The Metro is entirely separate from this: its own company, its own infrastructure, its own electrification system and no shared track. The two systems only meet at interchange stations.
Who actually operates the Metro?
The system is owned by a public company belonging to municipalities and the state. The actual operation is run by a contracted company from the world of international metro operators and system manufacturers. This separation between ownership and operation is standard for modern driverless metros – but it's practically invisible from the outside.
Does the Metro really run without a driver?
Yes, operation is fully automatic. There's no driver's cab in the trains; at both ends sit passengers with an unobstructed view of the line. Staff are present in the network, but not as drivers. For photography that's an advantage: the front perspective from the moving train is freely accessible.
How do I tell the Metro and S-tog apart?
The quickest way is via the power supply and vehicle size. The Metro draws power from a side-mounted conductor rail and runs short, narrow trains. The S-tog runs under overhead line with noticeably larger vehicles, such as the fourth-generation S-tog. There's also the line naming: M for the Metro, letters for the S-tog.
Is the Metro a railway operator?
No, and that's why you won't find it in any EVU directory either. Metro systems are subject to their own regulations and are separate from railway law – similar to a tram in Germany. That matters for operator collections: the Metro belongs in the local-transport category, not the railway category.
Who built the vehicles?
The rolling stock comes from Italian rail vehicle manufacturing, now part of Hitachi Rail. Driverless metro systems are usually procured as a complete package of vehicles, signalling and operations-control technology, because the components only work together. That's an important difference from the railway, where vehicles and infrastructure are procured separately.
Where can I see proper railway vehicles in Copenhagen?
At Copenhagen Central Station. That's where long-distance services, S-tog and Öresund traffic come together, with vehicles such as the IC3 among others. For the Swedish side of the Öresund link, Hyllie is worth it; for freight, Fredericia in Jutland is a better bet.
Who owns the tracks Danish trains run on?
Banedanmark is responsible for the national railway network. The Metro has nothing to do with this: its tunnels and stations belong to the Metro company itself. Another example of how completely different areas of responsibility exist side by side in the same city.
Can I photograph in the Metro?
Photography for private use is usually unproblematic in publicly accessible areas, but is subject to the operator's house rules. Tripods, flash and shots that disrupt operations are regularly restricted. What generally applies is summarised in the piece Am I allowed to photograph public transport?.
What other railways run in the surrounding area?
Besides DSB and the S-tog, Lokaltog operates regional lines on Zealand. The associated corporate group is described under Lokaltog. If you want to compare metro systems, Metro Warszawa gives you an eastern European counterpart with a completely different history.

The operational level in the railway operator database
Who actually runs the trains, with keeper markings and identifying features on the vehicle.
DSB S-tog A/S
DSB S-tog A/S carries the suffix for Copenhagen's rapid urban rail. Behind it stands a closed system with its own power supply and its own vehicle family.
Long-distanceDSB (Danske Statsbaner)
DSB stands for Danske Statsbaner, the Danish state railway. Its background explains a quirk that strikes every spotter in Denmark immediately: vehicles carry a litra instead of a class number.
Local & regionalLokaltog A/S
Lokaltog A/S stands for Danish regional and local rail services. The name says it all – and Danish special characters decide whether you can find your sighting again later.
Local & regionalArriva Tog A/S
Arriva Tog A/S carries the Danish word for train in its name. Its setting explains a basic fact of the Danish network: in regional services, diesel operation is the norm, not the exception.
Typical vehicles
DSB S-tog (4th generation)
The fourth S-tog generation shapes local transport in Copenhagen: a fully walk-through articulated train on its own electrification system, separate from the rest of the network.
ClassDSB IC3 (MF Litra)
No European train is as easy to identify as the IC3: the rubber-nose front forms a walk-through gangway when coupled – a feature found nowhere else.
ClassDSB IR4 (ER Litra)
The IR4 is the electric answer to the IC3: the same rubber-nose front, but a pantograph on the roof. Here's how to tell the two apart with confidence.
Where you will find Metro Kopenhagen
Spotting locations where you will regularly come across vehicles from this organisation – with viewpoints, the best light and coordinates.
Copenhagen Central Station
Copenhagen Central Station is the only major European terminus with a timber train shed – and at the same time the place where Danish local traffic, Öresund traffic and long-distance services towards Germany all overlap. Understand the hall, and you get the complete Danish vehicle picture here in two hours.
Border stationHyllie and the Öresund Link
Hyllie is the first station on Swedish soil after the Öresund Link – and so the place where four things change at once: electrification system, direction of travel, currency and jurisdiction. Operationally one of the most interesting points in Scandinavia, though surprisingly monotonous in terms of rolling stock.
Freight hubFredericia
At Fredericia, Denmark's only two main axes cross: the north-south line through Jutland and the east-west link over the Little Belt towards Funen and Zealand. That makes the station the place with the country's highest freight share – and one of the few genuine junction stations in Scandinavia.
More companies
DSB Danske Statsbaner
Denmark doesn't identify its vehicles with class numbers but with letter classes – the Litra. Add to that two electrification systems in one small country and a state railway that gave up freight operations more than two decades ago and now runs passenger services only.
InfrastructureBanedanmark
Banedanmark operates the state rail network in Denmark. The company runs no trains itself, but decides on the electrification system, signalling technology and access – and so on which vehicles even make it as far as Copenhagen.
GroupLokaltog
Lokaltog brings together the remaining private railways on Zealand and Lolland. Unlike the big Danish operators, the company owns its own routes – and runs on them exclusively with diesel multiple units, in the middle of an otherwise heavily electrified country.
BrandMetro Warszawa
Metro Warszawa is the name of an urban transport system with two lines, not of a railway company. The operator is a company owned by the City of Warsaw, the vehicles don't carry European vehicle numbers, and the track doesn't belong to the national infrastructure manager. That's exactly where most entries go wrong.
