Key takeaways
- The ICE 4 is the capacity backbone of German ICE services, not a record-breaking vehicle.
- Powercar concept: powered cars are added to the train in variable numbers – this produces different train lengths.
- Fastest way to identify it: very long, no power cars at the ends, blunt nose.
- 250 to 265 km/h – slower than the ICE 3, but with significantly more seats.
- Fleet size and deployment keep growing and shifting – figures and route assignments are only a snapshot.

Identifying features
Is this really the class in front of you?
- Very long train with no power cars at the ends – passenger windows run right through to the front of the train
- Blunter, taller nose than the ICE 3; the front doesn't taper to a flat point
- Wide, dark-tinted window band running the entire length of the train
- Pantographs on only a few cars – the rest of the roofline looks uncluttered
- Vehicle numbers in the 412 and 812 series
- Bicycle-space pictograms on the longer variants
Updated: August 2026 – A very long white train with no power cars at the ends, a tall, blunt nose and a window band that seems to go on forever: that’s the ICE 4 of Class 412. It’s not the fastest ICE, but it’s the one that moves the most people. This page shows you how to identify it, what’s behind the powercar concept, and how to photograph it well.

What is the Class 412 (ICE 4)?
The Class 412 is the ICE 4, a high-speed multiple unit with no power cars at the ends. It’s rated for 250 km/h, with the thirteen-car variant rated for 265 km/h, and has been in scheduled service with the Deutsche Bahn group since late 2017. The intermediate cars carry numbers in the 812 series.
Its standout feature is the powercar concept. Instead of putting power cars at the ends or spreading the traction evenly across the whole train, the 412’s traction equipment sits in individual, fully equipped intermediate cars. A train is then assembled from unpowered cars plus a matching number of these powercars. If a longer train is needed, more cars and powercars are added – the vehicle concept stays the same.
That makes the ICE 4 a business answer to a simple observation: most of the German long-distance network doesn’t allow 300 km/h. Where speed is already limited by the route – its upgrading is decided by DB InfraGO – extra seating capacity is worth more than a higher top speed. That’s exactly where the ICE 4 belongs, unlike the ICE 3 of Class 403, which is optimised for high-speed lines.
The fastest way to identify it
Check the front of the train
Passenger windows running all the way to the front? Then the ICE 1 and ICE 2 are ruled out – they have windowless power cars.
Assess the nose
Does the nose look tall and blunt rather than flat and pointed? That's the key difference from the ICE 3. The ICE 4 has a noticeably more compact, upright front end.
Judge the length
Twelve or thirteen cars is a strong indicator. Only the ICE 1 reaches similar lengths – but it has power cars and a raised-roof restaurant car.
Read the number
412 on end cars and powercars, 812 on the intermediate cars. That settles the identification for good.
Exactly where on the vehicle these numbers appear is shown in the guide Finding the train number; the structure of the twelve-digit number is explained in the article on the UIC number.
Nose beats length
Train lengths are hard to judge from the platform because your view breaks off at the end. The shape of the nose, on the other hand, you can see in a second: flat and pointed → ICE 3, tall and blunt → ICE 4.
Context: capacity instead of top speed
| Vehicle | Maximum speed | Concept | Strength |
|---|---|---|---|
| ICE 4 (Class 412) | 250 to 265 km/h | Powercars in variable numbers | many seats, flexible train length |
| ICE 3 (Class 403) | 330 km/h | distributed underfloor traction | high-speed lines |
| ICE 3neo (Class 408) | 320 km/h | Velaro platform, multi-system capable | fast and cross-border |
| ICE 1 (Class 401) | 280 km/h | two power cars | classic long trains for long-distance services |
| ICE T (Class 411) | 230 km/h | tilting technology | winding existing lines |
The table shows why several ICE generations are procured in parallel: they solve different problems – and the locomotive-hauled ICE L from Talgo solves yet another one. The ICE 4 mainly replaces the oldest long trains and covers high-demand routes, while the ICE 3neo of Class 408 covers the fast, cross-border connections. The full comparison is in the article ICE classes 1 to 4.
Which ICE 4 variant was it?
Seven, twelve or thirteen cars – log the length, not just the class.
Spotting: what train length means for your viewpoint
A thirteen-car ICE 4 doesn’t fit every shot or every platform equally well. For choosing a viewpoint that means:
- End of the platform, not the middle. Only from there do you get the front and several cars into a coherent frame.
- Look for distance. A full-length shot of the train needs considerably more distance than an eight-car ICE 3. A viewpoint with a clear view over several hundred metres is gold, such as the Geislinger Steige offers on open track.
- Favour major hubs. Trains stand there longer, so you can count cars, read numbers and work without rushing. An overview is in the article on the best stations for trainspotting in Germany.
- Document the car formation. For a vehicle with variable length, the configuration is genuine information – and one you can’t reconstruct afterwards.
Slipstream: especially long-lasting with long trains
A passing ICE first creates a pressure wave and then a strong suction effect towards the track. On a thirteen-car train this suction lasts correspondingly long – the train is several hundred metres in length. Consistently stay behind the safety line, step back for announced passages, secure your tripod, bags and camera strap, and only move forward again once the train has fully passed. The rules are set out in the guide on safety distance at the track. Track areas and operational railway land are not permitted vantage points.
Photo tips for the ICE 4
- Three-quarter angle. About 30 to 45 degrees to the vehicle axis shows the upright front and the flank at the same time – shot head-on, the ICE 4 looks flat.
- Expose tightly. All that white burns out quickly in sunshine; detail lost in blown-out white can’t be recovered afterwards.
- Short shutter speed. 1/1000 s is a starting point at 250 km/h, and often still too long.
- One record shot per train. A photo where the vehicle number is legible makes the sighting verifiable, regardless of how good the main shot turns out.
The basic technique is covered in the guide how to take good photos of trains, the focal-length question in the guide to the best telephoto lens for railway photography.
The powercar principle compared with other traction concepts
The ICE family now has three fundamentally different ways of housing traction within a train. The ICE 4 sits exactly between the two older solutions.
- Power cars. All the traction sits in one or two dedicated vehicles at the ends of the train. Advantage: clean separation, simple maintenance. Disadvantage: two vehicles with no seats and high axle loads.
- Fully distributed traction. Motors and converters sit under many cars. Advantage: low axle loads, good acceleration, every car usable. Disadvantage: the technology is spread across the whole train and the train length is fixed by design.
- Powercars. The traction sits in individual, fully equipped intermediate cars. Advantage: the train length can be varied without touching the vehicle concept – you simply add more cars and more powercars. Disadvantage: some cars carry heavy equipment, and power output only grows in steps.
It’s exactly this third approach that explains why the ICE 4 comes in several lengths and why all the variants nonetheless carry the same class number. It isn’t a kit of different vehicles, but one vehicle with a variable configuration. For spotters, that’s why the car count becomes the real piece of information for this class – it’s the only feature that distinguishes the variants. Where the trains stand long enough, such as at Hamburg Hauptbahnhof, counting them takes two minutes.
Common mix-ups
It points to the ICE 4 if …
- the train is very long and has no power cars at the ends
- the nose looks tall and blunt
- pictograms indicate bicycle spaces
- the number begins with 412 or 812
Look more closely if …
- you only have a front-on shot and can't judge the train length
- a short, seven-car variant is running
- the train is backlit and the nose shape looks flat
It's not an ICE 4 if …
- one end of the train is a windowless power car – then it's an ICE 1 or ICE 2
- the nose tapers to a flat point – then it's an ICE 3
- the body is tapered at the bottom and tilts in curves – then it's an ICE T
If the train is long but has windowless ends and a car with a raised roof, you’re looking at the ICE 1 of Class 401.
Verdict
The ICE 4 is the most pragmatic ICE generation: not the fastest, but the one that fits the German network best. To identify it, the nose shape is enough – tall and blunt rather than flat and pointed – combined with its striking length. What makes it interesting for spotters is its variants: a seven-car and a thirteen-car train are the same class, yet two very different sights.
In short
Very long, no power cars at the ends, tall blunt nose, 250 to 265 km/h: that's the ICE 4 of Class 412. Always note the car count alongside the number – for this vehicle, that's the real piece of information.
Car formation and number in one place
Log the variant, number, date and station – that's how a log becomes genuinely useful later on.
Summary
- The Class 412 is the ICE 4, a multiple unit whose traction sits in individual powercars.
- The number of these powercars can be scaled up or down, which is why there are different variants.
- You can identify it by the combination of great train length, no power cars at the ends, and a blunt nose.
- Areas of use and fleet numbers change constantly as the fleet continues to grow.
Frequently asked questions
What is the Class 412 (ICE 4)?
The Class 412 is the ICE 4, a high-speed multiple unit with no power cars at the ends. Its traction sits in individual powered cars known as powercars. Depending on how many powercars are fitted, trains of different lengths result – seven-, twelve- and thirteen-car variants.
How fast does the ICE 4 go?
The maximum speed is 250 km/h, with the thirteen-car variant rated for 265 km/h. This makes the ICE 4 slower than the ICE 3, but it offers significantly more seats. On most routes, that's the more relevant advantage.
What is a powercar?
A powercar is an intermediate car with a complete set of traction equipment under the floor. The train is made up of unpowered cars plus a chosen number of these powercars. This lets the power output be matched to the train length instead of developing a separate vehicle for every variant.
How do I tell the ICE 4 and ICE 3 apart?
Both have no power cars at the ends and windows running right to the front. But the ICE 4 has a blunter, taller nose, while the ICE 3 tapers to a flat point. The ICE 4 is also considerably longer in its long variants. The vehicle number settles it for good: 412 instead of 403, 406, 407 or 408.
Why is the ICE 4 slower than the ICE 3?
Because it was built for a different job. The ICE 3 is designed for maximum speed on high-speed lines, the ICE 4 for capacity and cost-effectiveness across the network. A large part of the German long-distance network doesn't allow 300 km/h anyway – there, seating capacity matters more than top speed.
How many cars does an ICE 4 have?
That depends on the variant: there are seven-, twelve- and thirteen-car trains. For identification in the field this means: counting cars helps you tell the variant, but not the class – all variants are Class 412.
Can you take bicycles on the ICE 4?
The longer variants have bicycle spaces, recognisable from outside by the corresponding pictograms. Whether and how these spaces can be booked on a given service depends on the current offering and changes – always check up to date.
What does the 93 at the start of the vehicle number mean?
93 is the UIC type code for high-speed multiple units. It appears in the first two positions of the twelve-digit vehicle number and applies equally to all ICE classes. The vehicles are only distinguished from each other by the following digits and the class number.

Who is behind it
Groups, brands, manufacturers and operators – who owns whom and how to recognise them out in the field.
DB InfraGO
DB InfraGO has been Deutsche Bahn's infrastructure company since 2024: network and stations under one roof, oriented towards the public good. It doesn't run any trains – but it decides where you're allowed to stand and which line is currently closed.
GroupDeutsche Bahn AG
Deutsche Bahn AG doesn't run a single train itself. It's a holding company under which dozens of independent companies hold their own licences, rolling stock and transport contracts. Spotting the red DB logo doesn't tell you the operator.
ManufacturerKnorr-Bremse
Knorr-Bremse is the rare case of a supplier whose name appears on almost every freight wagon in Europe. The code KE in the brake marking stands for Knorr-Einheitsbremse (Knorr standard brake) – and anyone who can read the marking also reads the brake setting, brake weight and often the approximate build year.
ManufacturerTalgo
Talgo doesn't build trains to the European standard design but to its own idea: short car bodies that rest on single-axle running gear between the cars. Once you understand the principle, you can spot a Talgo at any distance – even when it says ICE on the side.
Where to see the DB Class 412 (ICE 4)
Specific viewpoints with lighting times, coordinates and an honest verdict on whether the trip is worth it.
Berlin Hauptbahnhof
Berlin Hauptbahnhof is no ordinary station, but a crossing structure: above the east-west Stadtbahn under a glass roof, below eight tracks in the north-south tunnel. Both levels demand completely different settings – knowing that in advance saves you half the visit.
Junction stationDresden Hauptbahnhof
Dresden Hauptbahnhof combines two terminal platform halls with elevated through tracks in between - and over it all lies a membrane roof that diffuses daylight evenly instead of breaking it into hard stripes. Add to that the Elbe valley line towards the Czech Republic: eastern Germany's most interesting international connection.
Mountain lineGeislinger Steige
The Geislinger Steige is one of the oldest steep inclines in Europe and, to this day, a place where you can hear the railway at work. Since the new high-speed line opened, fast long-distance traffic runs elsewhere – what remains is freight traffic under full load, regional services, and photo spots you have to walk to.
Junction stationHamburg Hauptbahnhof
Hamburg Hauptbahnhof funnels the whole of Germany's north-south traffic, plus the route to Scandinavia, onto a handful of tracks. That makes it one of the most rewarding spots in the country – and one of the most uncomfortable. Plan around the crowding and you get a hit rate here that hardly any other station can match.
