Key takeaways
- 193 isn't a special Slovenian number: across Europe it stands for Siemens' multi-system Vectron.
- Quickest way to identify it: four axles, Vectron front, several pantographs, number starting 193.
- Slovenia runs on 3 kV DC – multi-system equipment is therefore a prerequisite for through trains to Austria or Hungary.
- The country code 79 in the UIC number reveals Slovenian registration, regardless of who operates the locomotive.
- Keepers and areas of operation change, because Vectron locomotives are often leased – check the current situation rather than older lists.

Identifying features
Is this really the class in front of you?
- Four axles in two bogies – not a six-axle design
- Typical Vectron front with an angular outline and a distinctive light cluster at the corners of the vehicle
- Vehicle number starts with 193; the full UIC number of a vehicle registered in Slovenia carries the country code 79
- Several pantographs on the roof – a clear sign of multi-system equipment
- Mostly at the head of freight trains, less often in front of passenger trains
- Liveries vary greatly depending on keeper and leasing company – the colour isn't a reliable feature
Updated: August 2026 – An angular, four-axle electric locomotive at the head of a freight train, the number starting with 193: then you’re looking at a Siemens Vectron – in Slovenia just as in Germany. What makes it interesting is that Slovenia runs on a different electrification system from its northern neighbours. This page shows you how to recognise Class 193 and why multi-system technology isn’t a gimmick here, but a prerequisite.

What is the SŽ 193?
Class 193 refers to multi-system electric locomotives from the Siemens Vectron family, which are used in Slovenia as in many other European countries. They are four-axle three-phase locomotives with the Bo’Bo’ wheel arrangement, suitable for freight and, in principle, also for passenger duties.
Important for understanding: 193 isn’t a Slovenian invention. The number is allocated across Europe to Vectron locomotives with multi-system equipment. Whether a locomotive is registered in Slovenia, Austria or Germany isn’t shown by the class number but by the country code in the full UIC number – for Slovenia, that’s 79.
Why the number 193 is the same across half of Europe
The classic German way of thinking – one number, one railway administration – no longer holds for modern interoperable locomotives. Class numbers such as 193 are tied to the technical design, not to a country. Only the twelve-digit UIC code makes the vehicle unambiguous.
How this code is structured, which digits carry the country code and how the check digit works are explained in detail in the article on the UIC number and its check digit. For Class 193 this isn’t a sideshow but the real key to identification – precisely because the livery doesn’t have to say anything about the keeper.
Count the axles
Four axles in two bogies. That immediately rules out six-axle machines such as the older Slovenian Class 363.
Place the front
The Vectron front looks angular and flat, with clearly separated light clusters at the corners of the vehicle. Rounded, forward-drawn fronts point to the Taurus design.
Check the roof
Several pantographs are a strong indication of multi-system equipment – a vehicle permitted to run on more than one network.
Read the UIC number
The country code at the beginning reveals the registration. 79 stands for Slovenia, 81 for Austria, 80 for Germany.
3 kV DC: the reason for all the technology
Slovenia is electrified at 3 kV DC. That sounds like a detail for engineers, but it has massive operational consequences: a locomotive coming from Austria can only continue in Slovenia if it can handle both systems.
| Country | Electrification system | Significance for through trains |
|---|---|---|
| Slovenia | 3 kV DC | Base system every Slovenian electric locomotive must be designed for |
| Austria | 15 kV / 16.7 Hz AC | System change at the border, multi-system locomotive or locomotive change required |
| Germany | 15 kV / 16.7 Hz AC | Same system as Austria, but far away from the Slovenian network |
| Italy | 3 kV DC | Same base system as Slovenia – technically the simplest neighbour |
| Hungary and Croatia | 25 kV / 50 Hz AC | Third system type, likewise only passable for through trains with multi-system equipment |
That also explains why so much attention at Slovenske železnice is focused on multi-system machines. Class 541, based on the Taurus design, serves the same purpose with a different generation of technology, while older machines such as Class 363 and Class 342 are pure DC locomotives and therefore can’t leave the network.
Keepers and duties change
Vectron locomotives are often leased and move between companies. Which machine is currently running for which operator, and on which routes, shifts with contracts and timetable years. Rely on current observation, not on older lists.
Follow cross-border traffic live
Community sightings show you which multi-system locomotives are where right now – handy for planning a photo trip.
Spotting and photography: what’s different in Slovenia
Slovenia is a small network with great appeal: mountain and karst lines, many tunnels, short distances between hubs. For spotters from Germany this means one thing above all – you can gather a lot of material here in a few days if your planning is right.
- Freight corridors first. Multi-system locomotives work where freight crosses system boundaries. Purely local lines, by contrast, produce hardly any Vectron sightings.
- Plan in hubs near the border. Where systems meet, the variety of vehicles is greatest – often there’s older stock standing alongside the 193.
- Optimise the light rather than the position. In narrow valleys and between tunnels, the window of good light is short. Check the direction of the sun beforehand, not on site.
- Always photograph the number too. A Vectron without a legible number is almost worthless for documentation, because the machines look very similar from the outside.
Another point concerns expectations. If you come from Germany, you know the Vectron as a run-of-the-mill vehicle that passes along every major freight line. In Slovenia it’s present too, but in a completely different setting: next to it stand six-axle DC locomotives from the 1970s, older railcars and modern low-floor trains. That very contrast is the real reward of a trip – you can get a single Vectron picture at home, but not the combination of several vehicle generations at one station.
How to work your way systematically towards an unfamiliar vehicle is described in the guide to identifying classes. And if you want to go deeper into research abroad, the guide to railway topics abroad has pointers on where international sightings are discussed and documented.
Safety comes first
Tracks, stabling sidings and depots are operational railway land in Slovenia too, and not a photo location. Photograph from the platform, from public paths or from bridges – and keep your distance from the platform edge, especially with freight trains passing through.
Common mix-ups
It points to Class 193 if …
- the locomotive has four axles in two bogies
- the front looks angular and the lights sit clearly at the corners
- there are several pantographs on the roof
- the number starts with 193
Look more closely if …
- the locomotive wears an unfamiliar leasing livery and you can't place the shape with certainty
- you only see it against the light or from behind
- the country code isn't legible – then it remains unclear where the vehicle is registered
It's not a 193 if …
- you count six axles – then older DC locomotives are candidates
- the front is clearly rounded and drawn forward – typical of the Taurus design
- there's no pantograph but an exhaust – then you're looking at a diesel locomotive
Conclusion
In Slovenia, Class 193 isn’t an exotic but part of a Europe-wide vehicle family – and that’s exactly what makes it interesting. If you want to identify it, work with the number of axles, the front shape and the number, not the colour. If you want to understand why it’s needed here, you have to start with the electrification system: 3 kV DC in the country, AC at the neighbours. Almost everything that shapes Slovenian cross-border traffic technically follows from that one sentence.
In short
Four axles, angular Vectron front, number starting 193: that's the multi-system Vectron. In Slovenia it's the answer to a 3 kV DC network surrounded by AC neighbours – and the full UIC number is the only thing that makes it unambiguous.
Your Slovenia sightings, properly documented
Number, location, date and photo in one place – so even after the trip you can still trace which machine you saw.
Summary
- Class 193 is the number range allocated across Europe to multi-system Vectron locomotives, and Slovenia uses it just like its neighbours.
- For identification, the number of axles, the front shape and the start of the number are enough – the livery won't help.
- The Slovenian 3 kV DC network is the reason multi-system locomotives get so much attention here.
- Because Vectron locomotives often change keeper, it's worth documenting every sighting with the full number and date.
Frequently asked questions
What is Class 193 in Slovenia?
These are multi-system locomotives from the Siemens Vectron family. The number 193 isn't a home-grown Slovenian one: it's used across Europe for Vectron locomotives with multi-system equipment. The country affiliation isn't contained in the class number but in the country code of the full UIC number – for Slovenia, that's 79.
How can I recognise a Vectron with certainty?
By the angular front with its characteristically arranged lights, by four axles in two bogies and by the number starting with 193. Several pantographs on the roof are an additional indication of the multi-system variant. The livery, on the other hand, is no criterion – Vectron locomotives run in a great many colour schemes.
Why does Slovenia need multi-system locomotives?
Because the Slovenian network is electrified at 3 kV DC, while its neighbours use other systems. Austria and Germany run on 15 kV at 16.7 Hz, Hungary and Croatia on 25 kV at 50 Hz. Without multi-system equipment, the locomotive would have to be changed at every system boundary.
Does the Slovenian 193 also run in Germany?
Class 193 Vectron locomotives are an everyday sight in Germany – though mostly with a German or Austrian keeper. Whether a particular locomotive registered in Slovenia turns up on a German line depends on approvals and diagrams, and changes all the time. The UIC number with the country code 79 is the reliable clue here.
How do I tell a Vectron from a Taurus?
Both are four-axle three-phase locomotives, but their front ends differ clearly: the Taurus, with its more rounded, forward-drawn front, looks softer, the Vectron more angular and flat. When in doubt, the number decides – 193 stands for the Vectron, 541 in Slovenia for the Taurus design.
Does Class 193 also haul passenger trains?
The focus is on freight, but the design is in principle also suitable for passenger duties. Which diagrams are actually worked with which locomotive changes with contract awards and timetable years – there's no fixed allocation.
How do I know exactly which 193 is in front of me?
By the full twelve-digit UIC number on the side of the vehicle. It contains the country code, class number, serial number and check digit and is the only truly unambiguous identifier. Only with it can a sighting be properly assigned later.
Where is the best place to watch Class 193 in Slovenia?
At junction stations with freight traffic and on the approach lines to the border crossings, because that's where multi-system locomotives inevitably come together. Which routes are currently served and how shifts with every timetable change – so plan with current information rather than older overviews.
