Key takeaways
- Lokaltog A/S is a Danish local rail company; "lokaltog" simply means local train in Danish.
- A/S is the Danish public limited company – the suffix tells you the country of registration, not the area of operation.
- Danish vehicle classes are called Litra and carry letter codes rather than numbers.
- æ, ø and å decide your archive search – get them wrong and you won't find your own sighting again.
- Databases list similar names more than once. Always note the full company name including its legal form.

How to recognise this operator
Is this really Lokaltog A/S?
- Country code DK in the data panel – Danish registration
- Legal-form suffix A/S on the company name, not AG or GmbH
- The name Lokaltog itself is clearly lettered on Danish vehicles
- Vehicle classes carry letter codes (Litra), not German-style class numbers
- Diesel railcars are the norm in Danish local traffic, not the exception
- Short trains of one or two units instead of long locomotive-hauled sets
Updated: August 2026 – A short diesel railcar stops at a small Danish platform, the vehicle carries a name you understand at once, and yet that evening you can’t find the sighting in your own archive. Lokaltog A/S is a good example of how, in Scandinavia, it’s not identifying the train that’s the problem – it’s finding it again. This page shows you what the company name reliably tells you – and why three letters of the Danish alphabet decide the quality of your documentation.

What is Lokaltog A/S?
Lokaltog A/S is a Danish local passenger rail company. The company name is unusually informative: “lokaltog” is not a made-up word in Danish – it’s the everyday word for local train or commuter train. Anyone reading the name already knows which market segment the company operates in. Behind the name stands Lokaltog, a holding company under which numerous former private railways have been brought together.
The second part of the name is the legal-form suffix A/S, Danish for aktieselskab. It roughly corresponds to the German Aktiengesellschaft (public limited company); the Danish equivalent of a GmbH is ApS. Both abbreviations are a reliable indicator of the country of registration – but explicitly not an indicator of where the company’s vehicles actually run.
Same core name, two entries
Alongside Lokaltog A/S, this database also has an entry for Lokaltog without a legal-form suffix. Whether this is the same company, a spelling variant, or two separate legal entities can only be clarified via the commercial register – which is exactly why we make no claim either way here. For your documentation this means: note the company name exactly as it appears on the vehicle, legal form included.
The company name as an identification aid
Company names in the rail sector fall roughly into three types, and Lokaltog A/S belongs to the most informative of them. This typology helps you in any country as soon as you’re faced with an unfamiliar company.
| Name type | Example pattern | What it reveals | What it doesn’t reveal |
|---|---|---|---|
| Functional name | “Lokaltog”, “Cargo”, “Rail Service” | the market segment | size, area of operation, owner |
| Origin name | a landscape or regional name in the company name | a geographic root | today’s actual area of operation |
| Invented name | fantasy and brand terms | nothing operational | everything else |
| Legal-form suffix | A/S, ApS, AS, AB, GmbH | the country of registration | the country of operation |
A functional name is therefore the best starting point you can get. By comparison: with Midtjyske Jernbaner, the company name carries a regional reference rather than a functional statement – there you first have to decode the geography before the name tells you anything. And yet even a functional name remains a classification, not a status report. Which services a local operator actually runs can change, and fleets get rebuilt. The only thing that stays reliably valid is what’s written on the vehicle itself. The guide Who’s actually running it? Identifying railway operators describes how to approach that information systematically.
Danish special characters and your archive
Now for the real problem. The Danish alphabet ends with æ, ø and å. These three characters constantly appear in place names, line names, station names and company names – and they’re the most common reason a carefully logged sighting later becomes untraceable.
Set one substitution rule
Decide once: æ → ae, ø → oe, å → aa is the classic variant. Alternatively, keep the original characters. Both work – switching partway through doesn't.
Also store the original
Write the place name correctly in the original field and the simplified form in a notes field. Then every search works, whichever spelling you happen to remember.
Watch your keyboard
On German keyboards, æ and ø are often confused with ä and ö. These are different characters – search won't match one for the other.
Think about sorting too
In Danish, æ, ø and å come after z. If your place list sorts them at the start, that's not a fault in your archive but a different sorting rule.
The same principle applies to Norwegian entries, which use the same three characters – for example Flåm Utvikling AS, where the å is already built into the company name. Setting yourself a rule early saves you having to merge duplicate entries later. The guide Keeping a sightings log shows how to stick to such conventions long-term.
An archive that still works in five years
Structured fields instead of loose notes – that's how sightings from abroad stay usable.
Litra instead of a class number
If you’re used to Germany, your reflex in Denmark is to look for a three-digit class number – and you won’t find one. Danish vehicle classes are called Litra and carry letter combinations such as MR, MF or ER. The system is described in detail on the Danish class pages of the database; for now, this rule of thumb will do: letters instead of numbers, and the letters stand for the build type and purpose.
In practice, you’ll mostly encounter diesel railcars such as the Litra MR/MRD or more modern units of the Desiro family with SA Litra in Danish regional services. In nationwide traffic, dominated by DSB, the IC3 with MF Litra is the best-known face. For you as an observer, the Litra designation is just as valuable as the class number is in Germany: it turns “saw a diesel railcar” into an analysable sighting.
The practical benefit shows up later, when sorting. “Red railcar in Denmark” can’t be compared to anything; “Litra MR, full vehicle number, place and date” can, instantly. And because Litra letters are short and memorable, you can note them down as the train passes even if the number itself goes by too fast. In that case, note the Litra plus the exact location rather than a half-guessed string of digits – an incomplete but honest entry is worth more in the archive than a wrong one.
Non-electrified is the norm
A large part of the Danish rail network has no overhead line. Diesel operation in regional services is therefore not a sign of falling behind, but simply the physical reality of the network. Responsibility for the condition and expansion of the state network lies with Banedanmark. For you in the field, that means two things: first, a diesel railcar at a Danish regional platform is nothing special worth noting – the vehicle number, on the other hand, is. Second, you won’t find pantograph shots on the same lines, which changes how you compose your photos.
Easy to document …
- at publicly accessible platforms with clear signage
- during longer stops, when you can read the data panel
- at hub stations, where several companies meet
Only with caution …
- with trains passing through without stopping – numbers are barely legible
- in backlight on north–south lines
- when you're unsure of the spelling of the place name
Never …
- from tracks, level crossings or operational access roads
- on stabling and workshop sites – that's private land
- by climbing over barriers of any kind
Safety abroad
Track areas, platform ends beyond the barrier, stabling sidings and workshop sites are off-limits in Denmark too, and are sometimes private land. Local rules and signage apply regardless of whether you understand them. Stick to publicly accessible locations – the basic rules are summarised in the article on keeping a safe distance from the track.
Common mix-ups
- Lokaltog as a generic term – “lokaltog” is also used quite generally in Danish for a local train. Not every mention refers to a company.
- A/S confused with AS – without the slash it’s the Norwegian legal form, with the slash it’s the Danish one. That’s a country indicator, not a typo.
- ä instead of æ, ö instead of ø – visually similar, technically different. Search engines and archives don’t treat them as the same.
- Litra mistaken for a number – MR is not an abbreviation of a numeric value but a standalone class designation.
- Similar company names treated as identical – the same core name doesn’t automatically mean the same company. Only the register can decide that.
Conclusion
Lokaltog A/S is a company whose name does half the work for you: local rail, Danish register, public limited company. The other half of the work happens in your archive – with special characters, spellings and the full company name. Master both, and you can keep Danish sightings just as tidy as German ones.
Verdict in brief
"Lokaltog" reveals the segment, "A/S" the country of registration. Everything else depends on whether you record æ, ø and å according to a fixed rule – otherwise you'll lose your own sighting in your own archive.
Summary
- The company name tells you two things for certain: Danish register (A/S) and local rail (lokaltog).
- Danish vehicles are tracked by Litra letters, not by German-style class numbers.
- Danish special characters aren't a matter of style – they're a search problem in your own archive.
- Recording the full company name keeps identically named entries apart.
Frequently asked questions
What does the name Lokaltog mean?
"Lokaltog" is Danish and means local train or commuter train. So the name directly describes the business area: services on regional lines away from the big long-distance corridors. Unlike a purely invented brand name, here you can actually infer the type of service from the company name.
What does the legal form A/S stand for?
A/S stands for aktieselskab and roughly corresponds to the German Aktiengesellschaft (public limited company). The Danish equivalent of a GmbH is ApS. The suffix tells you which country the company is registered in – not where its vehicles actually run.
Why does the vehicle carry DK and not D?
The code before the hyphen in the data panel names the country of registration. Danish-registered vehicles carry DK, German ones D, Norwegian ones NO. Two letters instead of one is perfectly normal and not a mistake.
What is a Litra?
"Litra" is the Danish term for vehicle class. Instead of a three-digit class number as in Germany, Danish vehicles carry letter combinations such as MR, MF or ER. The system is explained in detail on the Danish class pages of the database.
Why do æ, ø and å cause problems in my archive?
Because every program handles them differently. Sometimes ø becomes o, sometimes oe, sometimes it stays as it is. If you later search using one spelling, you won't find the other. Set yourself a fixed rule and stick to it – or store both variants in the same entry.
Are there several entries with a similar name?
In vehicle and company databases, similar or identical core names occur fairly often, for example with and without the legal-form suffix. Whether the same company or a different one is behind it can only be clarified via the register. So always note the full company name exactly as it appears on the vehicle.
Do Danish local trains run on diesel?
A large part of the Danish network has no overhead line. Diesel operation is therefore the norm in regional services, not a sign of outdated technology. Which vehicles are actually used changes with procurement – check the current situation.
What should I note down for a sighting in Denmark?
Full vehicle number, country code, Litra designation, place and time. The place name belongs in the archive in its original Danish spelling – if necessary, add a simplified variant too, so you can find it in every search field.

Vehicles in the rolling stock database
DSB MR / MRD
MR and MRD are two Litra for one two-part unit – the classic Danish diesel railcar that shaped the regional lines before the IC3.
ClassDSB Desiro (SA Litra)
The Desiro Classic at DSB is an old acquaintance from Germany: the same two-part diesel railcar as Class 642, just with Danish markings.
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.

Who is behind it
Groups, brands, manufacturers and operators – who owns whom and how to recognise them out in the field.
Banedanmark
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.
State railwayDSB 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.
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 Kopenhagen
Metro Kopenhagen runs without a driver, around the clock. It's not a railway operation, doesn't belong to the state railway, and shares neither track nor electrification system with the city's other rail traffic. That's exactly why it so often ends up in the wrong category in sighting lists.
