Key takeaways
- Six axles are the identifying feature: Co'Co' is the exception among European electric locomotives.
- Litra EG means electric locomotive in the Danish designation system – the E stands for the propulsion.
- Two power systems enable through trains between the Danish 25 kV network and the German 15 kV network.
- A pure freight locomotive: you won't find it in front of passenger trains.
- Services and assignments change – freight operations are restructured often, so check the current status.

Identifying features
Is this really the class in front of you?
- Six axles in two three-axle bogies – unusual for European electric locomotives
- Powerful, box-shaped body with cabs at both ends
- Equipment for two power systems, identifiable from the roof equipment
- Litra marking with an E at the start instead of a German class number

Updated: August 2026 – Six axles, a box-shaped locomotive body, a heavy freight train on the hook: the DSB Litra EG is among the most striking locomotives in northern Europe. It’s a dual-system machine and therefore one of the few Danish builds that’s technically usable on German lines too. This page explains the Litra system, the identifying features and the role of the power systems.

With freight trains, often only a brief moment remains. With Traintrack the sighting is captured in seconds.
What’s behind the DSB Litra EG?
The Litra EG is a six-axle electric locomotive for heavy freight service. It comes from Siemens and belongs to the EuroSprinter family, from which numerous locomotive builds for European railways have emerged over the years. Its wheel arrangement is Co’Co’ – six axles in two three-axle bogies.
The most technically interesting feature is dual-system capability: the machine operates under both the Danish 25 kV system and the German 15 kV AC voltage. That means freight trains can be taken across the system boundary without a locomotive change being needed. At the border station of Padborg, they therefore roll straight through where other machines end their run.
The DSB’s Litra system in a minute
Anyone coming from Germany looks for a class number – in Denmark there isn’t one. Instead, DSB works with Litra, the Danish term for the class designation:
- The first letter states the propulsion type. E for electric traction vehicles, M for combustion-engined, i.e. diesel, vehicles.
- The second letter distinguishes the build. EA and EG for the electric locomotives, ME for the diesel locomotives, MF and MG for the diesel multiple units.
- The Copenhagen S-train carries its own letter combinations, because it operates with its own DC system.
This one rule carries surprisingly far. If the marking starts with E, it’s an electric machine; if it starts with M, a diesel vehicle. How to use such systems methodically instead of guessing individual features is shown by the guide to identifying rolling-stock classes.
Count the axles
Six axles in two three-axle bogies are rare in Europe. That immediately rules out almost all modern four-axle electric locomotives.
Check the type of train
A heavy freight train on the hook fits the EG. It's not expected in front of passenger trains – then it's worth a look at the marking.
Read the Litra
An E at the start of the marking confirms electric propulsion, the second letter narrows down the build. Together with the running number, the machine is uniquely identified.
Why the power systems decide the operating radius
Hardly any technical detail determines as strongly where a locomotive can turn up at all as the power system. In northern Europe, two worlds meet:
- Denmark has electrified its main lines with 25 kV / 50 Hz.
- Germany, Austria and Switzerland use 15 kV / 16.7 Hz.
- The Netherlands operate with 1.5 kV DC – a third system right next door.
A locomotive that masters only one system ends at the border. That’s exactly why the DSB Litra EA, as a pure 25 kV machine, is as a rule not found in Germany, while the EG is technically capable of it. The same logic explains why modern multi-system locomotives such as the DSB Vectron have gained importance in cross-border traffic.
The high proportion of unelectrified lines in the network run by Banedanmark remains notable. It explains the country’s strong diesel tradition – from diesel multiple units to heavy machines such as the DSB Litra ME.
In practice, that yields a simple test question: Is there overhead line above the track? If not, every electric locomotive is ruled out, regardless of its technical capabilities. If there is, the next thing that decides is the system – and with it, the question of whether the vehicle was even allowed to get this far. In northern Europe, these two questions answer a surprising number of identification problems before you’ve even looked at a single detail on the vehicle. Further east the picture shifts again: at the Öresund link at Hyllie, the Danish network meets the Swedish one.
A third layer comes into play with assignment: whoever operates a freight locomotive is not necessarily the one who procured it. Freight operators get restructured, and vehicles are leased and passed on via lessors such as Rentalok. So when logging a sighting, try to also note the keeper marking – it’s often more informative than the livery.
| Observation situation | Chance of a sighting | Why |
|---|---|---|
| Danish freight corridors | high | core deployment area of heavy electric locomotives |
| Border-area lines between Denmark and Germany | medium | dual-system capability makes through trains technically possible |
| Marshalling yards, visible from outside | medium | train formation and standing times, but no access |
| Pure passenger lines | low | other builds in service |
| Unelectrified lines | ruled out | diesel vehicles run there |
Freight traffic is especially changeable
Services, assignments and company structures in freight traffic change more often than in passenger traffic. Which machine is deployed where can shift noticeably within a year – check the current status rather than older lists.
Freight trains are hard to plan for
Community sightings show you what's currently on the move – the best basis for a spontaneous trip.
Spotting and photography in freight traffic
Freight trains make different demands than passenger trains: they come less regularly, often pass through without stopping, and are longer than the frame allows. At the freight hub of Fredericia you have the best odds for this.
Focus on the locomotive
The train is too long for a full shot. Frame the locomotive and the first wagons – that tells more than a cropped freight train.
Choose a fast shutter speed
For passing trains, 1/1000 s is a workable starting point. Adjust it to speed and distance rather than treating it as a fixed rule.
Make the six axles visible
A slightly side-on perspective shows both three-axle bogies. Shot head-on, the decisive feature is lost.
Follow up on the marking
If the number wasn't legible as it passed, a second shot of the side wall helps – especially with trains that stop only briefly.
How to observe marshalling yards and freight hubs safely and sensibly is covered in the guide to marshalling yard spotting. How the twelve-digit vehicle number is structured and what the country code 86 means is explained in the article on the UIC number and its check digit.
Operational land is off limits
Marshalling yards, stabling sidings and track areas are operational railway land and not a photo spot – in Denmark just as in Germany. Photograph only from publicly accessible areas and keep your distance from the platform edge. Where barriers stand, access ends.
Common mix-ups
It points to a Litra EG when …
- you count six axles in two three-axle bogies
- a heavy freight train hangs behind it
- the marking starts with an E
- the vehicle is running in Denmark or in cross-border traffic near the border
Look more closely when …
- you can't reliably count the axle number from your position
- the machine is stabled and visible without a train
- an unfamiliar livery obscures the design language
It isn't an EG when …
- you only count four axles
- the marking starts with M – then it's a diesel vehicle
- it's a multiple unit with no separate locomotive
Verdict
Among Danish locomotives, the Litra EG is the most striking: six axles, heavy freight trains, two power systems. The axle count is enough to identify it, the Litra system to place it, and a look at the power systems is enough to answer the question of its operating radius. Anyone wanting to understand why certain vehicles cross borders and others don’t will find a textbook example here.
Quick verdict
Six axles, a freight train on the hook, Litra marking with E, two power systems mastered: that's the Danish EG. It's technically usable across borders – where it actually runs changes with the services.
Capture even fleeting sightings
Freight trains don't wait. With Traintrack, number, location and date land in the logbook immediately – before the memory fades.
Summary
- The Litra EG is the heavy freight locomotive of the Danish rail world and, technically, a Siemens EuroSprinter machine.
- Its dual-system capability makes it the rare Danish locomotive that can also turn up in Germany.
- Axle count, train type and the Litra marking are enough to identify it.
- Because freight traffic is rarely predictable, observation spots with high freight volumes and patience pay off.
Frequently asked questions
What does Litra EG mean?
Litra is the Danish term for a vehicle's class designation. The E at the start stands for electric propulsion, the G distinguishes the build within the electric traction vehicles. By the same logic, the EA is another electric locomotive build, while designations starting with M mark diesel vehicles.
How many axles does the Litra EG have?
Six, spread across two three-axle bogies – the wheel arrangement Co'Co'. That's rare in Europe: most modern electric locomotives are four-axle. Counting axles is therefore the fastest way to identify it, and works from a great distance too.
Why does the EG master two power systems?
Because Denmark is electrified with 25 kV / 50 Hz and Germany with 15 kV / 16.7 Hz. A locomotive that masters both systems can take freight trains across the system boundary without needing a locomotive change. That saves time and staff – and is exactly what makes the EG interesting for observers on the German side in the first place.
Can I see the Litra EG in Germany?
Technically it's designed for that, since it also masters the German 15 kV system. Whether and to what extent it actually runs on German lines depends on services, contracts and approvals, and it changes. Don't rely on older information – check current sightings.
What is the EuroSprinter family?
EuroSprinter is a locomotive family from Siemens, from which numerous builds for various European railways have emerged over the years. They share a basic design and drive technology; wheel arrangement, power systems and approvals differ by customer. The EG is the six-axle freight variant of this line.
Does the EG also haul passenger trains?
That's not its intended purpose. The EG is a freight locomotive: six axles for high tractive effort, designed for heavy trains. You'll find other builds in front of Danish passenger trains. If you see a six-axle machine in front of a passenger train, it's worth taking a second look at the marking.
Where is it worth observing freight trains?
On lines with high freight volumes and at marshalling yards, as far as they can be seen from publicly accessible areas. Freight traffic follows a fixed schedule less often than passenger services, so you need patience – or current sighting data showing what's currently on the move.
How do I identify the exact machine?
By the Litra marking with running number and by the full UIC number. The country code 86 stands for Denmark. Photograph the marking as well – especially with freight trains passing through quickly, that's often your only chance to secure the number reliably.

DSB Litra EA / EB
The Litra EA is DSB's main-line electric locomotive. Its code follows the Danish Litra system, in which the first letter names the type of propulsion.
Electric locoDSB Vectron
The DSB's Vectron locomotives are four-axle electrics from the Siemens platform on Denmark's 25 kV network. Here's how to identify them, place the Litra designation, and find good spots.
Diesel locoDSB ME (Diesel)
The Litra ME is the DSB's classic six-axle diesel locomotive – diesel-electric, boxy, and closely related to its electric sisters. Here's how to identify it out in the field.
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.
ManufacturerRentalok
Rentalok belongs to the Danish leasing tier – companies that provide traction without running trains themselves. For spotters, that's the moment where logo, keeper and operator finally come apart, and only the data panel can help.
Where to see the DSB Litra EG
Specific viewpoints with lighting times, coordinates and an honest verdict on whether the trip is worth it.
Fredericia
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.
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.
Border stationPadborg
Padborg isn't a pretty station, but it's a logical one: this is where Danish electrification ends, where freight trains towards Scandinavia change locomotives, and where practically all land traffic between Denmark and Germany passes through. Bring patience and you'll see an operation that barely exists anywhere else anymore.
