Key takeaways
- The P is the whole difference: P stands for pasażerska, i.e. passenger locomotive, U for general-purpose.
- The EP07 and EU07 are barely distinguishable visually – if you can't read the marking, you can't identify it with certainty.
- Four axles set it apart instantly from the six-axle freight classes.
- The train behind the locomotive is a strong clue: passenger coaches point to the EP07.
- Duties and operators change with contract awards and timetable years – always check current information.

Updated: August 2026 – The PKP EP07 is the passenger-service variant of the classic Polish four-axle locomotive family. If you want to tell it apart from the near-identical EU07, you need to be able to read – visually there’s barely anything separating the two types. This page shows what the P in the name means, which features actually matter, and what to watch for when observing it.
Spotted an EP07? Note the letters.
With near-identical classes, the marking is what decides – with Traintrack it's logged in seconds.
What is the PKP EP07?
The EP07 is a four-axle electric locomotive for passenger services, built by Pafawag in Wrocław for the Polish network electrified at 3 kV DC. The name is a shorthand for its job: E for electric drive, P for pasażerska – passenger locomotive – and 07 as the design number.
It belongs to the same vehicle family as the PKP EU07, but is tailored to passenger service rather than general-purpose use. That’s exactly where the most common misidentification in Polish rail operations comes from: two classes, one appearance, a single letter that tells them apart.
Decoding the code: why P isn’t U
The system used by Polskie Koleje Państwowe encodes drive and use in the name. The second position is the decisive one, because it says what a vehicle was built for.
| Second position | Meaning | What that means in operation |
|---|---|---|
| P | pasażerska – passenger | Designed for passenger trains, train heating and passenger operation |
| U | uniwersalna – general-purpose | Both possible, passenger and freight |
| T | towarowa – freight | Heavy trains, high tractive effort, usually six axles |
| M | Shunting and manoeuvring duty | Short distances, low speeds |
| N | Railcars and multiple units | No separate traction vehicle on the train |
This scheme applies equally to diesel and electric vehicles. An SM is a diesel shunter, an EN an electric multiple unit like the PKP EN57. The structure doesn’t change, however exotic the vehicle.
Read first, then guess
With the EP07 and EU07, all the technical knowledge in the world is no use if you can't decipher the marking. So plan your position so the side wall with the designation and number is in view – not just the front.
Identification in the field
Count the axles
Four axles on two bogies. Six axles rule out the EP07 immediately and point to the heavy freight classes.
Look at the train
A continuous set of passenger coaches is a strong clue. Freight wagons argue against it – then a general-purpose or freight locomotive is more likely.
Read the letters
EP or EU: that's the real decision. If the locomotive is standing still, use the chance – the markings are hard to catch while it's moving.
Note the running number
The three-digit number after the class identifies the individual machine. Without it, the sighting stays incomplete.
How to find and interpret markings and train numbers systematically is covered in the guide to decoding train numbers.

Photographically: the side wall is the information
For a class that’s only distinguished from its sister class by two letters, the photographic priority changes. The most beautiful front-on shot is worthless if no one can tell what’s in it.
- Three-quarter view as the default. Around 30 to 45 degrees to the vehicle axis shows front and side wall at once – and with it, the marking.
- Use dwell times. At stations with turnaround times you can work calmly instead of hoping to catch it on the fly during a run-through.
- Choose the right focal length. Too short and the marking becomes unreadable; too long and the train no longer fits in the frame.
- Light from the side. Low morning or afternoon light picks out the edges of the boxy bodyshell; midday light flattens it.
The basics are covered in the guide to taking good photos of trains, and lens choice in the guide to focal length in train photography.
Location and safety
Track areas, shunting yards and operational railway land are off limits – no photography there, not even briefly. Stay on publicly accessible platforms behind the safety line or on freely accessible paths. Exactly which rules apply depends on the operator and the individual case.
The UIC number as a second layer
When two classes are barely distinguishable visually, a second source of information helps: the twelve-digit UIC number carried by every vehicle in European service.
It contains a code for the vehicle type, the country code – 51 for Poland –, a vehicle number and a check digit. That lets you place a vehicle even if you don’t know the national scheme by heart. For sightings you plan to analyse later, it’s the most stable identifier of all, because it doesn’t change with liveries or operator changes.
Two numbers, two purposes
The class designation tells you what kind of vehicle is in front of you. The UIC number tells you which specific vehicle it is. For a complete sighting you need both – especially with closely related classes like the EP07 and EU07.
In practice that means a simple rule for framing: the side wall belongs in the shot, not just the front. A front-on photo of an EP07 often can’t be reliably distinguished from an EU07 later on – making the shot worthless as evidence, however good it looks photographically.
A second practical tip concerns the order of operations when observing. Note the number first, then take the photo. Whoever raises the camera first and tries to read afterwards has usually already missed the train. With stationary trains during a turnaround, the order doesn’t matter – on run-throughs, it decides whether the sighting is usable at all.
Once you’ve internalised this routine, you automatically collect better data. And with a class family whose members differ only by letters, that’s exactly the difference between an archive and a photo collection.
Common mix-ups
It points to an EP07 if …
- the marking starts with EP07
- you count four axles on two bogies
- a set of passenger coaches is attached
- the UIC number carries the country code 51
Look more closely if …
- you only see the front – the EP07 and EU07 can't be told apart that way
- the locomotive carries a special livery
- the vehicle has been modernised and differs in detail from the standard appearance
It's not an EP07 if …
- you count six axles
- the marking starts with ET or S
- the vehicle is a multiple unit with no separate locomotive
The six-axle PKP ET22 already stands out just by its axle count. Much closer is the more modern express locomotive PKP EP09, which carries the same P but is a different design with its own styling.
Verdict
The EP07 is a good example of how identifying a vehicle isn’t always a matter of shapes and proportions. Here, a single letter decides, and it appears in only one place: on the vehicle itself. Whoever accepts that and chooses their position accordingly will identify it reliably – whoever guesses from the gut will regularly get it wrong.
Quick verdict
E for electric, P for passenger, 07 for the design. Four axles, boxy bodyshell, passenger coaches behind it – and the marking as the final word against the near-identical EU07.

Summary
- The EP07 is the variant of the classic Polish four-axle family tailored to passenger service.
- Its name follows exactly the same logic as every other PKP vehicle: drive type, use, design number.
- For identification in the field, what counts is axle count, train type and, above all, the legible marking.
- Whoever documents it notes letters, running number, operator and date – liveries change more often than the technology.
Frequently asked questions
What does EP07 mean?
E stands for electric drive, P for pasażerska – passenger locomotive. The 07 is the design number. The Polish system thus packs two pieces of information into the name: what a vehicle runs on, and what it's built for. An EP07 is therefore an electric passenger locomotive of design 07.
How do I reliably tell the EP07 and EU07 apart?
Only via the marking on the vehicle. Both belong to the same four-axle family and look extremely similar. A strong clue is the train: a locomotive in front of a pure passenger coach set is more likely an EP07, one in front of freight wagons more likely an EU07. But it's only certain once you've read the letters.
How many axles does the EP07 have?
Four axles, spread across two two-axle bogies. This wheel arrangement reliably sets it apart from the heavy, six-axle freight locomotives on the Polish network. Counting axles is therefore the first and quickest identification step – it works even from a distance and in poor light.
What electrification system does the EP07 run on?
On 3 kV DC, the standard on the electrified Polish network. That confines the locomotive to Poland and similarly electrified sections elsewhere. Cross-border workings generally require multi-system vehicles or a locomotive change.
What's the difference between the EP07 and EP09?
Both carry the P for passenger service, but belong to different designs. The EP09 is the newer machine, built specifically for fast express duty, and with its more modern-styled front end looks noticeably different from the boxy EP07. The design number in the name is the decisive piece of information here.
Do you also see the EP07 in front of freight trains?
That's the exception. Its design targets passenger trains, and in regular service you'll accordingly find it in front of passenger coach sets. General-purpose types and the heavy freight locomotives handle freight duties. There are exceptions in operation everywhere – but they're not the rule.
Where do you find the EP07?
On electrified main lines with locomotive-hauled passenger trains and at larger stations with turnaround times. Because diagrams, operators and vehicle assignments shift with every timetable year, no fixed route can be given – check the current picture via real-time data and community sightings.
What does the three-digit number after EP07 tell you?
It's the running number of the individual machine within the class – comparable to the running number in the German system. Together with the letters it identifies the vehicle uniquely. For a proper sighting log, it should always be noted, not just the class designation.
