Key takeaways
- Skd isn't a class number but a category: the letter code stands for the diesel-powered shunting locomotive in the Norwegian system.
- The quickest way to identify it: short body, one cab, no pantograph, data panel marked Skd.
- Where it works tells you more than its shape: small shunters operate wherever wagons are moved, not where passengers are carried.
- Fleet numbers and whereabouts change constantly – many vehicles of this type are now with museums, contractors or private sidings.
- Restraint is compulsory for photography: shunting yards are operational railway land, not publicly accessible photo spots.

Identifying features
Is this really the class in front of you?
- Very short body with only one cab – no continuous locomotive body like on mainline locomotives
- No pantograph on the roof: the Skd runs on diesel, even under overhead wire
- Data panel starts with the letters Skd, followed by the type number 220
- Usually stands alone or with a handful of wagons in the station area rather than at the head of a passenger train
- Noticeably short compared with the passenger coaches beside it – a useful gauge when scanning across the platform
- Conspicuous warning stripes and shunter's steps at the rear are typical for this vehicle type
Updated: August 2026 – A small, squat diesel locomotive shunting two wagons on a Norwegian station track: that’s exactly what the NSB Skd 220c stands for. It’s not a mainline locomotive but a working vehicle for station operations – and a good example of just how logical the Norwegian naming system is. This page shows you how to identify it, where you’re realistically likely to find one, and what to watch out for when photographing it.

What is the NSB Skd 220c?
The NSB Skd 220c is a diesel-powered shunting and small locomotive of the Norwegian state railway. Its job isn’t hauling trains along the line, but moving individual wagons and short groups of wagons within stations, workshops and on private sidings. NSB has traded as Vy since 2019, which is why you’ll come across both abbreviations in vehicle lists.
You can already tell that from the designation: Skd, in the Norwegian system, is the category code for the Skiftetraktor with a diesel engine – literally the shunting machine with internal combustion power. Only after that come the type number 220 and the variant letter, which marks a sub-variant. Once you know this pattern, you can place Norwegian vehicles you’ve never even seen before.
The Norwegian naming system in three building blocks
Norway names its rolling stock differently from Germany. Instead of a continuous three-digit class number, a letter code for the category comes first – and it tells you straight away what you’re looking at.
| Abbreviation | Vehicle type | What you see in the field |
|---|---|---|
| El | Electric locomotive | Pantograph on the roof, cabs at both ends |
| Di | Diesel locomotive | No pantograph, exhaust, used on non-electrified lines |
| Skd | Diesel shunting locomotive | Short body, one cab, station rather than mainline service |
| Type + number | Multiple unit | A continuous unit of several cars, no separate locomotive |
| BM + number | Power car within a multiple unit | Marked on the side of the vehicle, usually a multi-car set |
Norway’s electric vehicles run at 15 kV, 16.7 Hz – the same AC system as Germany, Austria, Sweden and Switzerland. That doesn’t matter for the Skd 220c, since it carries its own diesel engine, but it does explain why Norwegian electric locomotives like the El 18 of NSB and Vy are technically closer to central European machines than the map might suggest.
Read the letter code
If Skd is marked on the side of the vehicle, the matter is settled: diesel shunting locomotive. El or Di, by contrast, point to mainline locomotives.
Check the roof
No pantograph, but an exhaust: that rules out every electric locomotive, whatever the vehicle's livery.
Judge the length
Use a passenger coach standing beside it as a gauge. Small shunters fall noticeably short by comparison – something you can see even from further away.
Watch what it's doing
Moving wagons, coupling, running a short distance and back again: that pattern of movement belongs to a shunting locomotive, not a mainline machine.
If you want to practise this process systematically, the guide to identifying rolling-stock classes sets out a sensible order for working through features – the broad ones first, then the finer details.
What small shunters are for in railway operations
Shunting and small locomotives are the least conspicuous vehicles on the network, and at the same time the ones without which nothing would run. They position wagons for loading, pull sets out of sheds, serve workshop tracks and take on light engineering-train duties.
| Task | What that means for spotting | Chance of a sighting |
|---|---|---|
| Moving wagons within a station | Short, recurring movements near the platform | medium to high |
| Workshop and shed duty | Vehicle often only partly visible, rarely photographable in the open | low |
| Private sidings and industrial track | Operating times hard to predict, ground mostly private | low |
| Engineering and works trains | Irregular, but often in unusual locations | variable |
| Museum and society operation | Predictable via event dates, good photo conditions | high on running days |
The key difference from a mainline locomotive: a Di 4 or a diesel railcar of the Di 8 type turns up in the timetable and is therefore at least somewhat predictable. A small shunter doesn’t. Its use depends on the needs of the day – and that’s in no timetable book. The same holds true compared with heavy freight locomotives like CargoNet’s El 14, which run on fixed routes.
Fleet and whereabouts change
Small shunters are sold, re-marked or withdrawn more often than mainline vehicles. Older fleet lists found online are therefore often out of date. Before a dedicated trip, check the current status – via society websites, community sightings and your own observation.

Spotting and photography: what’s different in Norway
Norway is a railway country with long distances, plenty of winter and plenty of tunnels. For photography, that first of all means short windows of light during the winter half-year, but extremely long light in summer. And for small shunters, it also means you’ll almost always be working from a distance, because the interesting areas aren’t publicly accessible.
Choose a viewpoint from the platform end
The end of the platform is usually the last publicly accessible point with a view into the shunting area. It goes no further than that – the operational area begins beyond the barrier.
Choose a generous focal length
Since you have to keep your distance, you'll need more telephoto reach than for a platform shot. Plan for more reserve rather than too little.
Include the data panel in the frame
For small shunters, the data panel is the real information. A photo without a readable data panel is only half the job for documentation purposes.
Plan for winter light
Snow acts as a huge reflector and brightens shadow areas, but it also pushes exposure metering towards underexposure. One to two stops of positive compensation is a reasonable starting point.
The guide to spotting at a marshalling yard describes how to observe such areas legally and sensibly. And because that can quickly become tricky without clear rules, the article on safe distance from the track is essential reading: track areas, stabling groups and depots are off limits – and no vehicle, however rare, changes that.
Common mix-ups
It points to a Skd if …
- the vehicle is short and has only one cab
- there's no pantograph on the roof
- the data panel starts with Skd
- it's moving wagons around the station rather than heading a train
Look more closely if …
- the vehicle is in a company or society livery and no longer carries NSB markings
- you only see the front and can't judge the length
- it's stabled together with engineering-train wagons – it could then also be a departmental vehicle
It's not a Skd if …
- a pantograph is fitted – then you're looking at an El locomotive
- the vehicle has cabs at both ends and a continuous locomotive body
- it's running at the head of a passenger train on the open line
Verdict
The NSB Skd 220c isn’t a vehicle for the big stage, but one for everyday station work – and that’s exactly what makes it worth learning about. Once you’ve correctly placed the letter code Skd, you understand the Norwegian system and will identify small shunters within seconds from then on. For German spotters, it remains a purely foreign vehicle: you can only see it on site, and only document it properly if you take note of the data panel, date and location.
In short
Short body, one cab, no pantograph, data panel marked Skd: that's the signature of a small shunter in Norway. It works within the station, not on the line – and its whereabouts change faster than online lists can keep up.
Summary
- The NSB Skd 220c belongs to the family of Norwegian small shunters that move wagons around a station instead of hauling trains along the line.
- The Norwegian naming scheme uses letters for the category and numbers for the type – once you understand it, you can place even unfamiliar vehicles.
- For German spotters the Skd 220c is a purely foreign vehicle: it doesn't run in Germany, and it can only be documented on site or through archives.
- Sightings are especially worthwhile when the number, date and location are all logged – for small shunters, whereabouts are often poorly documented.
Frequently asked questions
What does the designation Skd 220c mean?
In the Norwegian system, the letters stand for the diesel-powered shunting locomotive, i.e. the Skiftetraktor with a diesel engine. The number 220 denotes the type, and the trailing letter marks a sub-variant within that type. Unlike in Germany, the category is already readable from the letter code alone, before you even see a number.
How do I tell a Skd apart from a Norwegian mainline locomotive?
By size and build. Mainline locomotives in Norway carry the abbreviations El for electric and Di for diesel-powered machines and have a continuous locomotive body with a cab at each end. The Skd is much shorter, has only one cab, and works within the station rather than on the open line.
Does the NSB Skd 220c also run in Germany?
No. Small shunters of this type are confined to the Norwegian network and neither approved nor intended for German operation. To see one, you need to travel to Norway or rely on archive material. That's exactly what makes it interesting for collectors of foreign sightings.
Why doesn't the Skd have a pantograph, given Norway is electrified?
Because shunting locomotives need to work independently of the overhead wire. In workshops, on sidings and on private tracks, overhead wire is often absent or switched off. Diesel traction solves that problem – which is why it's the standard for small shunters worldwide, even on electrified networks.
Where are the best chances for a sighting?
At stations with stabling and workshop areas, on private sidings, and with heritage railways and societies. Exactly where individual vehicles are kept today changes with sales and overhauls – don't rely on older lists, check the current situation before your trip.
Am I allowed into shunting areas to take photos?
No. Tracks, stabling groups and depots are operational railway land and generally private property. Photos are taken from publicly accessible spots – from the platform, a bridge or an adjoining road. That applies in Norway just as much as in Germany.
How do I properly log a small-shunter sighting?
With the full data panel reading, date, location and a note on the livery. Ownership and location change more often for small shunters than for mainline vehicles, and publicly available fleet lists are often incomplete. Your own note is often the more accurate source as a result.
Is the Skd 220c still in regular use today?
Vehicles of this type come from an older procurement generation, and the operating status of individual machines varies widely. Some still work for industrial operators, others are preserved in museums or stored out of use. A blanket statement about the current fleet wouldn't be credible – researching the specific vehicle is the only way to be sure.
