Key takeaways
- Dual-system locomotives: The 362 and 363 handle both 3 kV DC and 25 kV / 50 Hz AC, so they can run right across the Czech Republic.
- The difference is in the bogies: Swapping bogies between two classes created the faster 362 and left the 363 at the lower maximum speed.
- Fastest way to identify it: angular Škoda front, four axles, number starting with 362 or 363.
- System change-over points are the best place to tell dual-system locomotives apart from single-system AC or DC locomotives.
- Into Germany, these classes can't run under their own power – they lack the German 15 kV system.

Updated: August 2026 – An angular Škoda front, four axles, and the locomotive simply carries on where others would need to be changed: Classes 362 and 363 are the Czech answer to a country with two electrification systems. This page explains what sets the two class numbers apart, why a bogie swap is behind it, and how to identify the locomotives with confidence in the field.

What are Classes 362 and 363?
Classes 362 and 363 are four-axle dual-system electric locomotives built by Škoda Transportation. They handle both 3 kV DC and 25 kV AC at 50 Hz, so they can run right across the Czech network without a locomotive change. The wheel arrangement is Bo’Bo’, and the body is the angular box design of the Škoda generation known in the enthusiast scene as “Peršing”.
Operationally, they’re the country’s all-rounders: they’re not tied to one part of the network and turn up in both passenger and freight service. In passenger service they run for the state railway České dráhy. Freight is handled by ČD Cargo, a separate group company. At Praha hlavní nádraží you can see both roles in a single morning. Where a pure AC locomotive like Class 242 and 243 has to stop at the system boundary, the 363 runs straight through.
Two electrification systems in one country
The Czech network is historically split: the northern part was electrified with 3 kV DC, the southern part with 25 kV / 50 Hz AC. The two systems meet at what are known as system change-over points, where the overhead line switches voltage.
For operations, that leaves three options: a locomotive change, a detour, or a vehicle that can do both. The third option is the most economical – and the reason why the Czech Republic runs an unusually large number of dual-system vehicles. Once you understand the principle, you can ask the decisive question of any Czech vehicle: is it tied to one system, or not?
The change-over-point trick
At a system change-over point, the wheat separates from the chaff: if a train runs straight through without a locomotive change, a multi-system vehicle must be leading it. That's the most reliable observation you can make without even looking at the number.
The bogie swap: how a 363 became a 362
This is where the Czech classification system gets really interesting. Class 362 is not a standalone new build. It came about when bogies were swapped between two existing classes: the dual-system locomotives received the bogies designed for 140 km/h, while the DC locomotives giving them up received the 120 km/h bogies in return.
Because this changed a feature relevant to their approval, the converted vehicles consistently received a new class number. The result:
- Class 362 – dual-system locomotive with the faster bogies, 140 km/h
- Class 363 – dual-system locomotive in its original form, 120 km/h
This logic is typical of the numerical system in use since 1988: the class number describes the technical condition, not the build history. You find the same mechanism with the DC locomotives of Classes 162 and 163 – there, the swap is the other half of the same story.
For German spotters, that takes some getting used to. In Germany, a class number usually stays the same even when a vehicle is converted; differences end up in sub-classes or a changed running number. The Czech Republic takes the opposite route and prefers to assign its own class. At first glance that makes the system look more confusing, but on closer look it’s actually more honest: if you know the class number, you also know the maximum speed and the electrification system.
In practice, that means: never rely on body shape alone. Two locomotives standing side by side at a station and looking identical can belong to different classes. At Brno hlavní nádraží they stand next to each other often enough for you to compare them directly. The first three digits of the vehicle number are the only reliable way to identify them correctly – and they appear on both the side wall and the cab.
Recognition and your chances in service
| Situation | Chance of a 362 / 363 | Reason |
|---|---|---|
| Hub stations with cross-system traffic | high | This is exactly what the locomotives were procured for |
| Near system change-over points | high | Through trains need multi-system vehicles |
| Pure DC lines in the north | medium | Possible, but pure DC locomotives compete there |
| Pure AC lines in the south | medium | Also possible, also in competition |
| Border stations towards Germany | very low | They don’t handle the German 15 kV system |
Fleet and deployment change
Diagrams, operators and liveries shift with every timetable year and with regional tenders. Treat lists from the internet as a guide, not a promise – and check them against current sightings.
Current sightings instead of outdated lists
In Traintrack you can see which vehicles were most recently reported – a better basis for planning your trip.
Spotting and photography
Axles first, then edges
Four axles rule out the six-axle Czech types. After that, the angular, raised front end tells you the Škoda generation.
The number as the final word
362 or 363 appear at the start of the vehicle number. Photograph the side markings too, or the sighting will stay imprecise.
Use standing times
At major stations with locomotive changes and turnaround times, you get a calmer opportunity for clean pictures – and more time to read the number.
Choose your position carefully
Platforms, public paths and bridges are fine. Track areas, operational railway land and stabling sidings are off limits – no exceptions, even abroad.
Photographically, the angular Škoda locomotives are more rewarding than the rounded earlier generations: the sharp edges still pick up definition even in diffuse light, and the raised front looks powerful in a three-quarter view. Problems only arise in harsh midday light, when the large smooth side panels blow out. An angle of around 30 to 45 degrees to the vehicle axis is a good starting point, since it shows both the front and the side markings at once. In the Elbe valley, Děčín hlavní nádraží offers long platforms and plenty of standing time for this.
For research beforehand, the guide to Czech sighting and photo sources is a good starting point. How to find the right train number and thereby the matching diagram is explained in the article on finding the train number; the general method for identifying unfamiliar vehicles is covered in the guide to identifying classes.
Common mix-ups
It points to the 362 / 363 if …
- the locomotive has four axles and an angular box body
- it passes a system change-over point without a locomotive change
- the number begins with 362 or 363
Look more closely if …
- the locomotive is running in an operator livery without conspicuous markings
- you only see the front view and can't read the number
- a modernised vehicle differs from the familiar shape
It's not a 362 / 363 if …
- the number begins with 162, 163, 242 or 243 – then it's a single-system locomotive
- the vehicle is noticeably more modern and flatter in shape, for example a 380
- you're looking at a six-axle locomotive
If you see a noticeably more modern multi-system locomotive, it’s usually a Class 380. And the dual-system locomotives for traffic towards Saxony are a family of their own – you’ll find them on the page about Class 371.
Conclusion
The 362 and 363 tell you, in a single pair of vehicles, how Czech railway engineering works: a country with two electrification systems needs locomotives that can handle both – and a classification system that honestly reflects technical changes. Once you understand the bogie swap, you also understand why the 162 exists.
In short
A dual-system locomotive with an angular Škoda front: the 362 is the faster version, the 363 the slower one – the difference is literally in the bogies. Both stay within the Czech Republic, because they lack the German electrification system.

Summary
- Classes 362 and 363 are the answer to a fundamental Czech problem: two electrification systems in one country.
- Both classes are technically closely related and differ mainly in their bogies, and therefore in their permitted maximum speed.
- For identification, the axle count, front shape and the first three digits of the vehicle number are enough.
- Operating areas and diagrams shift constantly – check the current situation before setting off specifically to find one.
Frequently asked questions
What is the difference between Class 362 and Class 363?
Both are four-axle Škoda dual-system locomotives with the same basic design. The practical difference lies in the bogies: the 362 is rated for 140 km/h, the 363 for 120 km/h. The 362 wasn't built new – it came about by swapping bogies between existing locomotives, a change that the Czech classification system consistently answered with a new class number.
Why does the Czech Republic need dual-system locomotives at all?
Because the country has a mixed electrification system: in the north, the overhead line carries 3 kV DC; in the south, 25 kV AC at 50 Hz. A single-system locomotive would have to be changed at the system change-over point. Dual-system locomotives run straight through, saving time, staff and an entire operating step.
Where do the nicknames Peršing and Eso come from?
In the Czech enthusiast scene, Peršing refers to the angular Škoda generation of the 1980s – the name plays on its stark, technical-looking design. Eso (Czech for "ace") has additionally become established for the 363 dual-system locomotives. Nicknames are a fixed part of vehicle culture in the Czech Republic and turn up in forums more often than the official class numbers.
Do these locomotives also run into Germany?
Not under their own power. Germany runs on 15 kV at 16.7 Hz, a system the 362 and 363 don't handle. For cross-border traffic in the Elbe valley, other dual-system locomotives designed for the German combination are used instead.
How can I recognise a dual-system locomotive from the outside?
Most reliably by its behaviour: if a locomotive passes a system change-over point without a locomotive change, it's multi-system capable. On the vehicle itself, the roof equipment helps, and above all the class number – in the Czech Republic, dual-system locomotives carry their own class numbers and are thereby unambiguously identified.
What did the designation mean before 1988?
Until 1988, the ČSD used a system of a letter plus a number group, with S for AC and T for diesel vehicles, for example. Since 1988, a purely numerical classification system has applied, in which the class number and the running number are written together. Older sources often still work with the letter designations.
Where do I have the best chances of seeing a 362 or 363?
At hub stations with traffic that crosses electrification systems, and near system change-over points. Vehicles stand there longer, are easy to see, and identification is straightforward. Which diagrams are actually worked by these classes, though, changes from one timetable year to the next.

ČD Cargo
ČD Cargo is the freight subsidiary of the Czech state railway and only came into being in 2007. Its vehicle fleet is considerably older: most of it dates from well before that. Add to that a quirk of the network – two electrification systems meeting in the middle of the country.
State railwayČeské dráhy (ČD)
Czechia runs on two electrification systems and a third class of vehicle that masters both. České dráhy classes its rolling stock with a scheme that captures exactly that – the first digit tells you traction type and overhead-line voltage in one go.
ManufacturerŠkoda Transportation
Škoda Transportation has been building locomotives, multiple units and trams in Plzeň for generations. Anyone spotting in Czechia can't avoid the company's products – from the boxy old electric locomotive types to the modern Panter family with its continuous window bands.
InfrastructureSpráva železnic
Správa železnic manages the Czech state railway network – separate from České dráhy, which is just one of several train operators there. The result is a country with unusually strong competition in long-distance services and two electrification systems on one network.

Bratislava hlavná stanica
Bratislava sits closer to Austria and Hungary than almost any other capital does to its neighbours. The main station clings to the slope above the old town, is visibly showing its age – and precisely because of that offers a mix of rolling stock that vanished further west long ago.
Junction stationBrno hlavní nádraží
Brno hlavní nádraží is the second most important rail hub in the Czech Republic – and one of the few large stations in Central Europe whose relocation has been debated for decades. Anyone who wants to experience the old layout in operation shouldn't put it off indefinitely.
Border stationDěčín hlavní nádraží
Děčín is the Czech border station in the Elbe valley – the point where the corridor between Hamburg, Dresden and Prague changes its locomotives. Between sandstone cliffs runs a volume of freight traffic that no other place in this guide matches.
Junction stationPraha hlavní nádraží
Prague is one of the few places in Europe where several long-distance operators openly compete for the same passengers. For spotters that means three railway companies, four neighbouring countries and a fleet ranging from vintage electric locomotives to tilting trains – all under the same platform roof.
