AWT – Advanced World Transport a.s.

Updated: August 2026 – If you document Czech freight trains, you’ll soon notice: in forums, photo captions and conversations, a class number is rarely mentioned. Instead, people talk about a bumblebee, a tomcat or a spectacle-wearer. This page takes AWT – Advanced World Transport a.s. as an opportunity to explain the Czech nickname system – and to show where its limits lie.

What is AWT – Advanced World Transport a.s.?

AWT is a Czech railway operator in rail freight. The company name is English – “Advanced World Transport” – and describes a logistics orientation without naming a specific area of operation. The suffix a.s. stands for akciová společnost and corresponds to a joint-stock company; the other common Czech legal form, s.r.o., corresponds to a limited liability company (GmbH).

In Czech freight, several companies operate side by side, including ČD Cargo, METRANS Rail and EP Cargo. Who runs which services depends on customers and contracts and changes – identification in the field only works via the vehicle itself. The largest provider in this market is the ČD Cargo group.

Why Czech locomotives have nicknames

Nicknames aren’t unique to the Czech Republic, but nowhere are they so firmly rooted in everyday language. The reason lies in the history of the designation systems: until 1988, Czechoslovak vehicles carried letter codes, and after that three-digit numbers. Strings of numbers are hard to remember – names aren’t.

Most of these names can be traced back to four sources:

Source	What is named	Example type
Appearance	Front end, window arrangement, silhouette	“Spectacle-wearer” for a distinctive front design
Animal comparison	Colour, sound, movement	Čmelák (bumblebee), Kocour (tomcat)
Material and construction	Materials used	Laminátka, after the plastic front end
Pop culture	Films, people, the spirit of the times	Bardotka, named after a film actress

The first three groups are self-explanatory once you know the translation. The fourth is the most interesting – and the least certain: with names from pop culture, the derivation is often told in several versions, and which one is true usually can’t be established any more. Treat such explanations as what they are: handed down, not documented.

Where nicknames help – and where they do harm

A simple rule of thumb helps with classification: the more specifically a name describes a visible feature, the more reliably it can be assigned to a design. Names referring to shape or material are therefore usually more precise than those from pop culture – the latter often stick to a vehicle without anyone being able to say why that particular one.

A nickname is an excellent reading tool. If you work through Czech sources without knowing them, you simply won’t understand what’s being talked about. As an identifying feature, on the other hand, it’s no good: it isn’t officially assigned, isn’t unambiguously tied to one class and is used differently from region to region.

How widely a name catches on depends hardly at all on how apt it is, but on how easy it is to say. That’s why nicknames often outlive the vehicles themselves: they migrate to successor designs, are carried over to modernised variants or stay attached to a family that has long since diverged technically. When reading older sources, you therefore always have to check which rebuild state is meant – the name alone doesn’t tell you.

A second point concerns translation. German-language sources sometimes translate Czech nicknames, creating forms that nobody uses in the original. So for your own documentation: note the name in the language in which you heard or read it, and translate it in brackets at most. That way it stays clear which source the designation comes from.

You’ll find specific vehicles in the class database – for example the shunting locomotive family 770 / 771, the diesel locomotives of Classes 742 / 743 or the electric locomotives of Classes 242 / 243. All three families go by names in everyday speech that you won’t find in official documents.

Recording sightings in freight

In freight especially, it’s worth taking an extra look at the wagons. A freight train almost always consists of vehicles from several keepers, often from several countries. The locomotive’s keeper marking therefore tells you nothing about the wagons behind it – and vice versa. If you roughly note the formation, such as “mostly open wagons” or “mixed train with tank wagons”, you make a sighting far more informative without having to read every single number.

Good places to practise this are close at hand for this company. The area around Ostrava hlavní nádraží is the centre of Czech coal and steel traffic, and that’s where exactly the mixed trains discussed here run. To the north, some of them leave the country via the Elbe Valley border station of Děčín hlavní nádraží. To the east, the route leads via the Slovak hub of Žilina. On the Polish side of the same territory, PKP Cargo, one of Europe’s largest freight operators, dominates the scene.

How to identify unfamiliar vehicles systematically is shown in the guide to identifying classes. Ways into the Czech source landscape are collected in the guide to spotting in the Czech Republic, and the method for identifying the company is set out in the guide Who’s actually running that train?.

Common mix-ups

• Nickname = class – one name can stand for several classes or rebuild states.
• Nickname = operator – vehicles of the same type run for many companies.
• English company name = international operation – the name says nothing about actual areas of operation.
• Namesakes in other countries – similar-sounding company names don’t imply any corporate connection.
• Keeper and operator – the keeper marking in the data panel names the keeper, not necessarily the company running the train.
• Livery as proof – colour schemes change with overhauls; the markings remain.

Verdict

AWT stands here as a representative of a phenomenon you’ll encounter all over the Czech Republic: vehicles have names, and in everyday use those names matter more than the numbers. If you know them, you’ll read sources much faster. But if you rely on them exclusively, you’ll produce sightings that nobody can resolve any more. The combination is what does it: the nickname for understanding, the vehicle number for documentation.
