Key takeaways
- The Twist is a PESA low-floor tram from Bydgoszcz and belongs to the newer generation after the Swing.
- Order of identification: first low floor, then articulated build, then car number – design details last.
- The biggest risk of confusion is with other PESA families, because the styling stays similar across generations.
- Trams sit outside the PKP letter system – no EN, no EU, no UIC number in the railway sense.
- No scheduled service in Germany: for sightings, you need to cross the border.

Updated: August 2026 – Anyone standing at a stop in a Polish city and watching a long, low-slung tram with a large windscreen pull in has a good chance of seeing a PESA Twist. This page explains how to identify it, how to tell it apart from its predecessor generation, and why the car number matters more for trams than any design feature.

What is the PESA Twist?
The PESA Twist is a multi-section low-floor tram from the Polish manufacturer PESA, based in Bydgoszcz. It belongs to the newer generation after the PESA Swing and is thus part of a vehicle family that has substantially driven the switch of Polish urban networks from high-floor to low-floor operation.
Important for identification: “Twist” is a marketing name. It generally doesn’t appear on the vehicle itself. What does appear is the transport operator’s car number – and that’s the only identifier that can back up a sighting later.
The order of identification that works in city traffic
Trams move slowly, but they rarely stand still for long. So it’s worth having a fixed order that goes from robust to fine-grained features.
Step 1: entrance height
Step-free from the kerb into the vehicle? Then it's low-floor, and so a modern generation. Steps mean a high-floor type and rule out the Twist.
Step 2: number of sections
Count the bellows gangways. Multi-section articulated trains of short bodies are the design principle of modern low-floor trams – single cars are not.
Step 3: cab shape
A large, deeply drawn-down windscreen and a rather angular front point to the newer PESA generation. This feature is a clue, not proof.
Step 4: car number
Check the number on the front and side against the operator's fleet list. Only then is the identification solid.
How to work through general features from coarse to fine – and which mistakes people typically make along the way – is described in the guide to identifying classes.
Designation systems: why trams have their own rules
For Polish railway vehicles, the system is clear and easy to learn. The first letter marks the traction type, the second the intended use:
| Code | First letter | Second letter | Meaning |
|---|---|---|---|
| EU07 | E = electric | U = universal | Electric universal locomotive |
| ET22 | E = electric | T = freight | Electric freight locomotive |
| EN57 | E = electric | N = railcar | Electric multiple unit |
| SM42 | S = diesel | M = shunting service | Diesel shunting locomotive |
| SA134 | S = diesel | A = railcar/railbus | Diesel railcar |
None of this applies to trams. Legally and operationally they aren’t railway vehicles, don’t carry a UIC vehicle number in the railway sense, and don’t appear in these code lists. Instead, there’s the manufacturer’s type designation – for Polish trams, traditionally a number with an appended N for standard gauge and lower-case letters for variants, as with the classic Konstal 105Na – along with the operator’s car number on the vehicle.
Anyone who still wants to understand the railway-side numbering logic, because they also photograph trains in Poland, will find the basics in the article on reading the UIC number and its check digit.
Fleets are a snapshot in time
Which operator runs how many Twist vehicles changes through follow-up orders, transfers and tenders. Use lists from the network as a guide, not as proof – and check the current situation before you travel.

Community sightings help with trip planning – especially on networks you don't see every day.
Where you’ll find the Twist – and where you’re less likely to
The Twist follows the procurement policy of Polish transport operators. That gives a simple rule: the more modern a network’s fleet, the higher the chance of newer PESA vehicles.
For German-speaking spotters, that means concretely: it doesn’t run in scheduled service in Germany. Anyone wanting to see one is best combining the visit with a city trip. Proximity to the border helps – Polish tram cities are well within reach from eastern Germany, without needing to plan a whole week around it.
In practice, you rarely find just one type on a Polish network. What’s typical is a mix of several generations side by side: old high-floor cars in reinforcement service, the first low-floor generation in between, and the newest deliveries on top. So anyone waiting for a Twist will almost inevitably also get the PESA Swing and the widely used Konstal 105Na in front of the lens – and, depending on the network, vehicles from other Polish manufacturers such as the Moderus Gamma LF06AC. Cars like these come from Modertrans Poznań, the country’s second major tram builder. That often makes a single afternoon at a well-chosen hub more productive than a whole tour of individual destinations.
A second point that helps with planning: trams run on a fixed frequency and turn back at terminal loops. Unlike with railways, you therefore don’t need to research diagrams to see a particular vehicle twice – if you stay in the same spot for an hour, you’ll very likely see the same cars again. That’s the simplest way to redo a shot that didn’t come out.
Photography tips for a long articulated train
Keep your distance, increase the focal length
Standing too close with a wide-angle lens tips the long train away towards the rear. More distance plus a moderate telephoto keeps the lines straight.
Look for a curve
On a curve the articulation becomes visible – the very feature that defines this design. On a straight, it disappears behind the side wall.
Choose the surroundings deliberately
Tram photos live off context. A recognisable building or a typical street scene turns a vehicle shot into a city shot.
Capture the number separately
An extra close-up of the car number saves guesswork in your archive later – especially with full advertising wraps that swallow the shapes.
How to bring together position, light and framing for trams is covered in the guide to tram photos. For preparing a trip to an unfamiliar network, the article on the tram spotter’s map helps, and how to document and share your finds cleanly afterwards is in the guide to reporting sightings.
Common mix-ups
It points to a PESA Twist if …
- the vehicle is low-floor throughout
- it's made up of several short, articulated bodies
- the cab shape looks angular and modern
- the car number belongs to the Twist series according to the fleet list
Look more closely if …
- the vehicle looks PESA-typical but older – then the Swing may be the answer
- a full advertising wrap obscures the contours
- the network runs vehicles from several manufacturers with a similar silhouette
It's not a Twist if …
- you count steps at the entrance
- it's a short solo car with no articulation
- the vehicle stops at a railway platform instead of a kerb-height stop
Conclusion
The PESA Twist is a typical example of how similar modern trams look to each other – and why identification needs a method rather than a gut feeling. Low floor and articulated build get you to the right vehicle family, and the car number provides the proof. And anyone who also knows that the PKP letter system deliberately doesn’t apply here avoids the most common beginner’s mistake when spotting in Poland.
In short
Modern PESA low-floor tram, multi-section, Polish urban network: that's the frame. The car number decides between Swing and Twist – design features are only a clue.

Summary
- The PESA Twist represents the newer generation of Polish low-floor trams from Bydgoszcz.
- For identification, what counts is the build and the car number; marketing names like Twist don't appear on the vehicle.
- Networks in use and vehicle numbers shift with tenders and follow-up orders – always check the current situation.
- Photographically, the Twist is an urban subject: tight street spaces, a lot of clutter around it, light that changes by the minute.
Frequently asked questions
What is the PESA Twist?
The Twist is a multi-section low-floor tram from the Polish manufacturer PESA in Bydgoszcz. It's built for urban line services, runs on tram tracks and stops at street-level stops. "Twist" is a manufacturer's product name, not an official vehicle designation.
How does the Twist differ from the PESA Swing?
Both are PESA low-floor trams from two consecutive vehicle generations. The Twist is the newer family and tends to look more angular in the cab shape. Because operators order individually, design features alone aren't reliable, though – the car number, checked against the fleet list, remains decisive.
Does the PESA Twist run in Germany?
Not in scheduled service. It's a vehicle of Polish urban networks. For spotters from eastern Germany, though, several Polish tram cities are within day-trip range. Which networks currently operate Twist vehicles can change with every procurement round.
Why doesn't a Polish tram carry a designation like EN57?
The PKP letter system applies exclusively to railway vehicles. There, the first letter stands for the traction type (E electric, S diesel), the second for the intended use – for example N for railcar. Trams aren't covered by this and carry a manufacturer's type designation and an operator's car number instead.
How many car bodies does a PESA Twist have?
That depends on the order: PESA supplies its low-floor families in different lengths and numbers of sections, because each network has different platform and capacity requirements. A blanket figure would be misleading – if in doubt, count the bellows gangways yourself.
What should I note down for a tram sighting?
Car number, line, date and location. It's also worth noting the livery, since full advertising wraps often change faster on trams than on locomotives. With these four or five fields, a sighting can be evaluated later rather than staying just a memory.
Where's the best place to photograph trams?
At stops, at terminal loops with standing time, and on curves where the articulated build shows. Always from a publicly accessible area. Depots and stabling sidings are operational railway land and therefore not a place to shoot from – even when no one seems to be around.
Do you need a telephoto lens for tram photos?
A moderate telephoto helps, because it keeps the proportions of a long articulated train together and blurs out distracting surroundings. In a tight street space, though, there isn't always room for that, so in practice a flexible focal-length range works well – better a zoom than two prime lenses.
