Key takeaways
- The company name explains the company: "Operador Ferroviário e Logístico de Mercadorias" means railway and logistics operator for goods.
- Portugal and Spain run on 1668 mm Iberian broad gauge – not on the European standard gauge of 1435 mm.
- The gauge is a real network boundary: crossing the Pyrenees only works by transshipping, regauging or a bogie change.
- Two gauges lie side by side on the peninsula – newer high-speed lines are built to standard gauge.
- Do not confuse it with the broad gauge in the east: the Russian gauge measures 1520 mm and is a completely different case.

How to recognise this operator
Is this really MEDWAY - Operador Ferroviário e Logístico de Mercadorias, S.A.?
- Data panel begins with P- – the country code for Portugal
- The company name states the business area itself: Mercadorias means goods
- The legal-form suffix S.A. rather than GmbH, AG, a.s. or Sp. z o.o.
- The train is made up of goods wagons, not coaching stock
- Vehicles are gauged to 1668 mm – wheelsets sit visibly further apart than on standard gauge
- Portuguese lettering and warning notices on the vehicle
Updated: August 2026 – A freight train in Portugal looks at first glance like a freight train in Germany: locomotive at the front, wagons behind. The decisive difference lies beneath the vehicles. Portugal does not run on standard gauge, but on the Iberian broad gauge of 1668 millimetres – which makes the border with France a technical network boundary as well. This page explains what the company name MEDWAY reveals and why gauge is the most important measurement in Iberian freight traffic.

What is MEDWAY?
MEDWAY is a Portuguese freight railway – and for once you don’t even have to research that, because the company name says it itself. “Operador Ferroviário e Logístico de Mercadorias” translates as railway and logistics operator for goods. That names the business area unambiguously: rail freight, complemented by logistics services around it.
The rest of the name is equally readable. S.A. stands for Sociedade Anónima, a legal form whose basic idea corresponds to the German public limited company – you encounter the same abbreviation in Spain, in Poland and in other Romance- and Slavic-influenced legal systems. And the country code on the data panel for Portugal reads P-. Portuguese passenger services, meanwhile, are run by the state railway Comboios de Portugal.
Everything else – ownership structure, fleet size, terminals, customer relationships, specific workings – is subject to change and is deliberately not asserted on this page. What does hold true permanently, and what actually helps you place things, is the technology of the network this company operates on. And that is unusual enough.
1668 mm: the Iberian broad gauge
European standard gauge measures 1435 millimetres between the rail heads. Portugal and Spain instead use the Iberian broad gauge of 1668 millimetres. The difference amounts to a good 23 centimetres – small enough to easily miss in a photo, and far too much for a vehicle to run on both gauges. On the Spanish side of the same broad-gauge network, Renfe shapes the picture.
Why 23 centimetres change everything
A wheelset consists of two wheels fixed firmly onto a single axle. The distance between their flanges is fixed by design and cannot be adjusted in service. If it does not match the gauge, the vehicle simply does not run – regardless of whether the traction current, coupling, brake type and certification would otherwise be fine. That is why gauge is the hardest of all network boundaries.
For freight traffic this means: a train from Portugal cannot simply keep rolling across the Pyrenees. At the junction with the French standard-gauge network, technical continuity ends. Anyone wanting to know how vehicle identification works on the other side of this boundary will find the French system explained on the SNCF page.
Three ways across the gauge boundary
Because cargo still has to cross the border, railway operations have developed three basic answers. All three cost time, and all three need fixed installations.
| Method | What happens | What makes it laborious |
|---|---|---|
| Transshipping | The load moves from a wagon of one network into a wagon of the other | Needs transshipment equipment and a matching load form; every consignment is handled individually |
| Regauging | The wheelset spacing is changed at a facility, the wagon itself stays the same | Only possible with purpose-built vehicles; the facility must lie on the route |
| Bogie change | The wagon body is lifted, the bogies are swapped | Needs lifting equipment, staff and a stock of matching bogies |
| Separate networks | No through running at all, both sides run their own workings | No transfer – the gauge boundary remains a genuine terminus |
What the gauge does not obstruct
- Traction current – 25 kV 50 Hz applies in Portugal as in parts of France
- The load units themselves, as long as they can be transshipped
- Contractual and logistical processes on either side of the border
- Making up a train within its own network
What the gauge hard-limits
- Through runs with an unchanged vehicle
- Short-notice help from vehicles of the neighbouring network
- Using multi-system locomotives as a universal solution
- Spontaneous diversions across the border
Rule of thumb: A multi-system vehicle solves a current problem, not a gauge problem. Anyone who confuses the two underestimates how fundamentally different the Iberian situation is from the central European one.
Which freight trains are currently running?
Community sightings show you which vehicles other spotters are currently reporting – at home and abroad.
Two gauges side by side
The situation is a layer more complicated still than it sounds so far. While the established older network stays on 1668 millimetres, newer high-speed lines on the peninsula are built to standard gauge. That means two gauges exist side by side there – not as a transitional state, but as a permanent structure.
Identify the network
Ask yourself first: older network or high-speed line? That determines which gauge lies under the train.
Match the vehicle
Vehicles are built for exactly one gauge, or explicitly designed to be regauged. A vehicle from one network does not turn up on the other by chance.
Think of freight separately
Freight trains are traditionally at home on the older network. What runs on a high-speed line follows different rules.
Note the gauge too
Record in the sighting which network you observed on. Without that detail, the most interesting part is missing later.
This, incidentally, is the point where the Iberian situation differs from the eastern European one: at the eastern edge of the standard-gauge network lies the Russian broad gauge at 1520 millimetres, operationally visible for example at PKP LHS. That is a different case entirely – different measurement, different history, different forms of operation. All they have in common is that standard-gauge vehicles get no further there either.
Current and vehicles on the peninsula
Portugal is electrified with 25 kV 50 Hz AC. Anyone coming from central Europe knows this system from northern and eastern France and from many new-build lines. So it is by no means exotic – and that is exactly what makes it a trap: the same traction current tempts you into assuming vehicles are interchangeable. Because of the gauge, they are not.
The vehicle types themselves follow the same design principles as everywhere else in Europe: heavy electric locomotives on main-line duty, diesel machines for non-electrified sections and for shunting, plus dual-power concepts. How such machines are built up technically can be traced well through central European representatives – for instance the main-line locomotive Siemens Vectron, the dual-power concept of the Stadler Eurodual, or, for shunting duty, the small locomotive family Y 8000.
| Type of service | Typical vehicle type | How to recognise it |
|---|---|---|
| Heavy main-line freight, electric | four- or six-axle electric locomotive | pantograph on the roof, long rake of goods wagons behind |
| Non-electrified section | main-line diesel locomotive | radiator housing and exhaust system instead of a pantograph |
| Shunting and trip working | compact shunting locomotive | short wheelbase, few wagons, slow running |
| New-build line | standard-gauge vehicles | a different network, a different gauge under the train |
A note on comparison: this overview describes vehicle types and duties, not the fleet of any particular company. Fleets change with procurement and lease agreements – check the current status where in doubt. How freight railways in other countries handle similar tasks is shown, for example, by the entry on Rail Cargo Austria.
Portuguese names and accents in the archive
The company name carries two acute accents: Ferroviário and Logístico. When jotting things down quickly, these are easily dropped – and then the archive search no longer finds the entry, because the stored spelling differs from the one typed in. The same applies to Portuguese place names with ã, õ, ç or é.
Is your Portugal sighting archive-ready?
- Company name written with correct accents
- An additional simplified spelling saved as a search aid
- Country code recorded separately from the vehicle number
- Full vehicle number noted
- Noted whether the network was broad or standard gauge
- Place, date and time documented
How to keep a logbook searchable even after years is described in the guide to a sightings logbook. The general approach to identifying a company is explained in the guide Who actually runs it? Recognising railway operators.
Safety comes first
Tracks, shunting areas and operational installations are off limits – abroad just as much as at home. Works, port and terminal sites are private property and must not be entered without permission. At border facilities, the additional rule applies: where photography is prohibited, no photos are taken. Observe only from publicly accessible locations.
Common mix-ups
- Equating Iberian and Russian broad gauge – 1668 millimetres in the south-west, 1520 millimetres in the east. Two different measurements, two different histories.
- Taking a multi-system locomotive for a universal solution – it overcomes electrical systems, not gauges.
- Same traction current, therefore same technology – 25 kV 50 Hz applies in Portugal as in parts of France; the gauge still differs.
- Taking standard gauge on the peninsula for a mistake – newer high-speed lines are deliberately built to standard gauge.
- Reading MEDWAY as a place name – the descriptive part of the company name comes after it and states the business area.
- Confusing the country code with the operator – P- states where the vehicle is registered, not who is hauling the train.
Conclusion
MEDWAY is the only Portuguese entry in this database – and therefore a good occasion to understand the decisive difference of the Iberian Peninsula. The company name answers the question of the business area on its own; the interesting information sits one level deeper, namely underneath the wheels. Anyone who grasps gauge as an independent network boundary places Iberian sightings accordingly with ease.
In short
"Operador Ferroviário e Logístico de Mercadorias" means railway and logistics operator for goods – the business area is in the name. The real distinguishing feature is the Iberian broad gauge of 1668 mm: it turns the Pyrenees border into a technical network boundary where only transshipping, regauging or a bogie change help you continue.
Summary
- MEDWAY is a Portuguese freight and logistics railway; the business area is stated literally in the company name.
- The Iberian gauge of 1668 millimetres technically separates the network from the French standard-gauge network.
- Moving wagons across the gauge boundary requires transshipping, regauging or a bogie change – a multi-system vehicle does not help with this.
- Anyone documenting Portuguese sightings keeps company names with accents, country code and gauge recorded separately.
Frequently asked questions
What does the name MEDWAY - Operador Ferroviário e Logístico de Mercadorias, S.A. mean?
The Portuguese name suffix is a self-description: Operador Ferroviário means railway operator, e Logístico adds the logistics part, de Mercadorias means "for goods". Together, then: railway and logistics operator for goods. S.A. stands for Sociedade Anónima, a legal form comparable to the German public limited company.
What gauge does the Portuguese railway network use?
Like Spain, Portugal runs on the Iberian broad gauge of 1668 millimetres, not on the European standard gauge of 1435 millimetres. The difference of around 23 centimetres sounds small, but is operationally decisive: a vehicle built for one gauge does not fit the other without conversion.
Can a freight train simply continue on across the Pyrenees?
No. At the border with the French standard-gauge network, a train meets a hard technical boundary. Three ways remain: transshipping the load, regauging the wheelsets, or changing the bogies. Each of these ways costs time and needs facilities. A multi-system vehicle explicitly does not solve this problem – it only helps with the traction current.
Is the Iberian broad gauge the same as the Russian broad gauge?
No, and this mix-up is common. The Russian broad gauge measures 1520 millimetres and concerns the eastern extension of the European network. The Iberian gauge measures 1668 millimetres and lies in the south-west. Both are wider than standard gauge, but they are also not compatible with each other.
Why are there two gauges on the Iberian Peninsula?
Because newer high-speed lines were built to standard gauge, while the established older network stays on 1668 millimetres. That means two gauges lie side by side on the same peninsula. For spotters this means: gauge is a real distinguishing feature between lines – and a reason why certain vehicles only appear on certain lines.
What electrical system is Portugal electrified with?
With 25 kV 50 Hz AC. That is the same system used in large parts of northern and eastern France. But the same current type does not mean the same gauge: even where the traction current matches, the vehicle still comes to a stop at the gauge boundary.
How do I recognise a vehicle registered in Portugal?
By the country code P before the keeper marking, which appears together with the vehicle number on the side of the vehicle. It states the country of registration. Which company is actually hauling the train on a given day is not shown by this – that is separate information.
How do I keep Portuguese sightings properly recorded?
Write the company name with the correct accents – Ferroviário and Logístico both carry an acute accent. Add a simplified spelling as a search aid, note the country code separately from the vehicle number, and record whether the line was broad or standard gauge. Without that detail you later lose the most interesting part of the observation.

Comboios de Portugal (CP)
Portugal runs on 1668 millimetres instead of 1435. That sounds like a footnote, but it's the reason almost nothing runs here that you'd recognise from Central Europe. Within that, Comboios de Portugal operates a network with three gauge and power combinations – and not a single freight train any more.
State railwayRenfe
Spain operates three track gauges and two electrification systems side by side – and Renfe runs trains that switch between two of them mid-journey. Once you can tell AVE, Alvia and Cercanías apart, you understand the whole system. A surprise is waiting on the platform, though.
