Key takeaways
- Metro systems are usually not railways in the legal sense. Licensing, oversight and regulations follow different rules than the national network.
- Metro Warszawa is a network and brand name – the company behind it is owned by the City of Warsaw.
- No twelve-digit vehicle numbers. Your usual identification method from the railway world doesn't apply here.
- Conductor rail instead of overhead line is the safest visual feature for telling Metro and railway apart.
- The suburban railway is something different: it runs as a genuine railway operator on the national network.

How to recognise Metro Warszawa
Does the train really belong to Metro Warszawa?
- Red M at the entrances – the network symbol that tells you straight away you're not entering a railway system
- Side-mounted conductor rail instead of overhead line: the clearest technical distinction from the railway
- Short in-house wagon numbers – if you're looking for a twelve-digit data panel, you won't find one
- Three vehicle generations: boxy cars from eastern European production, a French-developed type, and a newer walk-through design
- Line numbers M1 and M2 instead of train categories – there's no train number in the railway sense
- City fare branding on vehicles and stations, shared with bus and tram
- No connection to the railway network – despite the same gauge, there's no operational link
Strengths and weaknesses
What the company stands for
- A closed system with a clear vehicle range – easier to get to grips with than any railway network
- Dense headways mean short waits between two subjects
- The contrast between several vehicle generations can be documented over just a few kilometres
- Warsaw offers Metro, tram, suburban rail and long-distance rail for comparison in a small area
Where it falls short
- Vehicles carry no European numbers – sightings can't be indexed as unambiguously as on the railway
- Photography in Metro stations is subject to house rules and isn't welcome everywhere
- Lighting conditions in the tunnel are demanding for vehicle photography
- There's no reliable, ongoing public source on the current makeup of the fleet
- Confusion with the suburban railway regularly leads to wrong entries in sighting lists
Updated: August 2026 – Under the centre of Warsaw runs a rail vehicle with a gauge of 1435 millimetres, electric, every two minutes. Even so, Metro Warszawa isn’t a railway – and the name doesn’t belong to a railway company either, but to a municipal operation with two lines. Skip this distinction and you end up with entries that can’t be sorted out later.
Record local transport separately from the railway
Two systems, two numbering logics. In the Traintrack app, your Metro and railway sightings stay cleanly apart.
Why the Metro and underground are legally not a railway
This is the point where beginners regularly go wrong, and it has nothing to do with technology. Metro and underground systems fall, in most European countries, outside general railway law. They count as a standalone mode of transport or are classed under tram law. In Germany, for instance, all underground railways run under tram construction and operating regulations – legally, a Hamburg underground train is a tram, even though a vehicle such as the DT5 runs through a tunnel there.
There are three consequences you need to know. First: licensing and oversight sit with different bodies than for the railway. Second: vehicle numbers follow no European scheme, but are internal to the operation. Third: the track doesn’t belong to the national infrastructure manager – in Poland, that means not PKP PLK, but the Metro operation itself.
Four rail systems in one city
Warsaw is a textbook case, because four systems exist side by side here that look similar at first glance.
| System | Legal framework | Electrification system | Vehicle number |
|---|---|---|---|
| Metro | municipal local-transport system, no railway law | 750 V DC, conductor rail | short in-house number |
| Tram | tram law | 600 V DC, overhead line | short in-house number |
| Suburban rail (SKM) | railway law | 3 kV DC, overhead line | twelve-digit, European |
| Long-distance and regional rail | railway law | 3 kV DC, overhead line | twelve-digit, European |
The vehicle number column is the decisive one. It tells you whether you can even record the vehicle using your usual railway method – and for two of the four systems, the answer is no.
Conductor rail is the fastest identifying feature
If there's no overhead line above the vehicle and instead a side-mounted conductor rail runs beside the track, you're very likely not looking at a railway vehicle. That holds across Europe and works even if you can't read a word of the local language.
Who’s behind the name
“Metro Warszawa” is the brand of a network. The company that operates it belongs to the City of Warsaw – not to the state railway holding company PKP, and not to any private group. Timetable, fares and the shared umbrella brand for all the city’s transport modes are the responsibility of the city’s transport authority, similar to a German transport association.
This is exactly where the most common confusion arises: bus, tram, Metro and the suburban railway SKM Warszawa appear under a shared municipal design. Operationally and legally, they’re four different worlds. SKM is a genuine railway operator and runs on the national network, as do Koleje Mazowieckie in regional traffic and PKP Intercity in long-distance traffic.
Check the track
A tunnel with conductor rail and platforms without overhead line means Metro. Overhead line and points laid out in the open mean railway.
Look for the data panel
If you find a twelve-digit number with a country code, it's a railway vehicle. If you find a two- to four-digit number, it isn't.
Note the line instead of the train category
The Metro has M1 and M2, but no train category and no train number in the railway sense. Note the line and the direction of travel.
File it in the right list
Keep local transport and railway separate. Otherwise you mix two numbering logics that can't be reconciled with each other.
Railway or local-transport system?
The electrification system and data panel carry the most weight – the line number alone proves nothing.
What you actually get to see in Warsaw
The fleet tells the network’s story in three chapters: boxy cars from eastern European series production dating from the early years, a type developed by Alstom, and a newer, fully walk-through design from the range of Siemens Mobility. How many vehicles of the oldest generation are still running keeps changing; there are no reliable public figures on that.
Above ground, the contrast is worth it. At the hub Warszawa Centralna stand long-distance and regional trains, while the tram, with its own very long vehicle history, runs through the city – types such as the Konstal 105Na have carried generations of Varsovians. For the system behind it, the piece Light rail or tram? is worth reading.
Document four systems in one day
Metro, tram, suburban rail, long-distance rail – log every sighting in the right context.
Which list does the sighting belong in?
Local-transport list when …
- the vehicle is powered via a conductor rail
- it doesn't carry a twelve-digit vehicle number
- it operates within a closed network
Check more closely when …
- a suburban railway is styled in city branding and looks like local transport
- a vehicle can use both overhead line and conductor rail
- a line runs in a tunnel but is connected to the wider network
Railway list when …
- a twelve-digit number appears in the data panel
- the vehicle operates on the national network
- a licensed railway operator is running the train
The middle column is the real stumbling block. The Warsaw suburban railway looks municipal but belongs entirely in the railway world – as does the Warszawska Kolej Dojazdowa with its own line west of the city.
Underground facilities have stricter house rules
Photography in Metro stations is often handled more strictly than on railway platforms; tripods and flash are usually excluded. Follow staff instructions and note that the rules on house rules at stations apply here in the same spirit, supplemented by the specifics of the public transport area.
Conclusion
Metro Warszawa is a network name, not a railway company – and that’s not a technicality, but the basis of every correct record. Licensing, oversight, track and vehicle numbers follow different rules than the railway, even though the gauge is the same.
In practice, a single glance is enough: conductor rail or overhead line. Whoever asks that question first correctly places every rail vehicle in Europe – and knows immediately which list the sighting belongs in.
In short
A municipal metro network, not a railway operator. No European vehicle numbers, no connection to the wider network – and therefore its own separate sighting list.
Sort your sightings by system, not by feel
Railway, Metro and tram follow three different logics. The app keeps them apart so your record stays accurate.
Summary
- If you're documenting rail vehicles in Warsaw, you need two separate systems: one for the railway, one for municipal local transport.
- Same gauge doesn't mean the same legal system – the Metro has no operational connection to the railway network whatsoever.
- The fleet tells Polish transport history in three chapters, from eastern European series production to western European manufacturers.
- The city is one of the few places in Europe where you can cleanly tell apart Metro, tram, suburban rail and long-distance rail in a single day.
Frequently asked questions
Is the Warsaw Metro a railway?
No. Metro and underground systems are, in most European countries, legally not a railway, but standalone local-transport systems, or are classed under tram law. In Germany, for instance, underground railways run under tram construction and operating regulations rather than railway construction and operating regulations. For Warsaw that means: its own track, its own licensing, its own oversight – and no connection to the network of PKP PLK.
Who operates the Warsaw Metro?
A company owned by the City of Warsaw. "Metro Warszawa" is the network and brand name under which this company operates – comparable to how a transport authority in Germany runs under a network name. It has no ownership or operational link whatsoever to the state railway holding company PKP.
Why can't I find a twelve-digit number on Metro cars?
Because the European vehicle numbering system applies to railway vehicles, and Metro vehicles don't count among them. They carry short in-house numbers that are only unique within the operation. So if you go looking using the method from the guide to the UIC number, you won't find anything – that's not an error, it's the right answer.
What's the difference between the Metro and SKM in Warsaw?
A fundamental one. SKM Warszawa is a genuine railway operator: it runs on the national network, its vehicles carry European vehicle numbers and are subject to railway oversight. The Metro does none of that. The two only share the city's fares and umbrella brand, which explains the confusion.
Which vehicles run on the Warsaw Metro?
Historically three generations: boxy cars from eastern European series production dating from the early years, a type developed by Alstom, and a newer, fully walk-through design from Siemens Mobility. How many of the oldest vehicles are still in service keeps changing – there's no reliable ongoing source for that.
Am I allowed to photograph in the Metro?
The operator's house rules apply to stations and vehicles, and underground facilities often interpret them more strictly than railway platforms do. Tripods and flash are regularly excluded. What generally applies in public transport is set out in the piece Photographing public transport; the technique is covered in the underground photography guide.
Can I track Metro trains live like railway trains?
Only to a limited extent. Metro systems don't feed position data into the usual railway data streams, and there's no positioning in the tunnel either. What's technically possible and where the limits lie is explained in the piece Tracking the underground live. For the railway side of Warsaw's transport, the usual tools work as normal.
Is the Warsaw Metro comparable to the Copenhagen Metro?
Yes in legal classification, only partly in operation. Metro Kopenhagen is also a municipal system outside railway law. It runs fully automatically without crew, though, while Warsaw operates with drivers. For the question "railway or not", that makes no difference.
Where can I see Metro and railway side by side in Warsaw?
At the central interchange points. Warszawa Centralna is the hub for long-distance and regional traffic, while the Metro runs below or alongside it on its own level. Within a few hundred metres you can document four different rail systems there – and you need to keep them cleanly separate.
Does the tram belong to the Metro too?
No, they're separate operations with their own fleets, even though both belong to city transport and use the same fares. The Warsaw tram network has its own, very long vehicle history, including the Konstal 105Na. How tram, light rail and underground differ systematically is explained in the piece Light rail or tram?.

The operational level in the railway operator database
Who actually runs the trains, with keeper markings and identifying features on the vehicle.
Szybka Kolej Miejska w Warszawie Sp. z o.o. (SKM Warszawa)
Szybka Kolej Miejska w Warszawie operates rapid urban rail services in Warsaw. The name element SKM is a generic term and appears in several cities.
Local & regionalKoleje Mazowieckie – KM Sp. z o.o.
Koleje Mazowieckie – KM Sp. z o.o. is a Polish local passenger operator. The name names the Masovian Voivodeship; in the train scene, double-deck vehicles are what stand out most.
Local & regionalWarszawska Kolej Dojazdowa Sp. z o.o. (WKD)
The WKD is a commuter railway in the Warsaw area. Its name says it literally: Kolej Dojazdowa means feeder or approach railway – its own type of railway alongside the main network.
Long-distancePKP Intercity S.A.
PKP Intercity S.A. is the long-distance passenger company of the Polish state railway group. Anyone wanting to classify its trains reads category, train number and train name separately.
Typical vehicles
Konstal 105Na
The Konstal 105Na has shaped Polish tram networks for decades. A boxy high-floor car, usually coupled in twos – and running in countless rebuilt variants.
ClassPKP EN57
The PKP EN57 is Poland's most-built electric multiple unit and has been the face of Polish local services for decades. Here's how to identify it and its many refurbishments.
ClassKoleje Mazowieckie Class 31WE (Stadler FLIRT)
The 31WE is the Polish FLIRT variant for Koleje Mazowieckie around Warsaw. The shared bogies make the family instantly recognisable.
ClassDT5 (Hamburg U-Bahn)
The DT5 is the current U-Bahn generation in Hamburg: three-part and walk-through along its entire length. That's exactly what separates it from the older DT4.
Where you will find Metro Warszawa
Spotting locations where you will regularly come across vehicles from this organisation – with viewpoints, the best light and coordinates.
Warszawa Centralna
Warszawa Centralna is Poland's central long-distance station – and one of the darkest major stations in Europe. Between concrete pillars and neon light, high-speed multiple units meet locomotive-hauled trains from the seventies. If you get on top of the lighting, you get a cross-section of Polish long-distance traffic.
Junction stationKraków Główny
Kraków Główny is the most important rail hub in southern Poland – and a station you barely see from outside, because a shopping centre stands on top of it. Under the roof, international trains towards Prague, Vienna and Budapest meet regional services to Upper Silesia and the Beskids.
Junction stationWrocław Główny
Wrocław Główny is one of the few large stations in Central Europe whose main building is a motif in its own right. Behind the Tudor façade lies a through station where traffic towards Germany, Upper Silesia and Warsaw converges – with vehicles ranging from older-generation electric locomotives to the newest multiple units.
More companies
Polskie Koleje Państwowe (PKP)
Polish locomotive designations are the most clear-cut numbering system in Central Europe: two letters tell you the traction and purpose before you've even read the number. The group structure behind them is considerably less clear – a lot of what's called PKP no longer belongs to it.
InfrastructurePKP Polskie Linie Kolejowe
PKP Polskie Linie Kolejowe holds Poland's tracks, points and platforms – the company runs no trains itself. The station building, though, belongs to a different company in the same group. Anyone who keeps the two apart understands Polish sightings much faster.
BrandMetro Kopenhagen
Metro Kopenhagen runs without a driver, around the clock. It's not a railway operation, doesn't belong to the state railway, and shares neither track nor electrification system with the city's other rail traffic. That's exactly why it so often ends up in the wrong category in sighting lists.
ManufacturerPESA Bydgoszcz
PESA Bydgoszcz grew out of a railway workshop and is today Poland's best-known rolling-stock builder. Elf, Link, Dart and the tram families shape the picture across the whole country – and with Class 633, a PESA railcar even appears on German vehicle lists.
