S-Bahn Berlin Class 483 / 484

Classes 483 and 484 are the newest generation of the Berlin S-Bahn: the 483 as a two-car unit, the 484 as a four-car unit with a walk-through gangway. Here's how to tell them apart with confidence.

Key takeaways

  • 483 and 484 are two lengths of the same vehicle type: a two-car and a four-car unit from the same class family.
  • The four-car unit is the break with tradition: for the first time in Berlin, you can walk through all four cars.
  • Visibly younger than 480, 481 and 485 – large glazed front end and a continuous light strip.
  • No roof pantograph, because the Berlin network runs on DC current drawn from the third rail.
  • Where they operate shifts with delivery progress and contract awards – check the current picture.

Is this really the class in front of you?

Tick off everything that applies to the vehicle you are looking at.

  • Very modern front end with large glazed areas and an LED light strip
  • Class 484: four cars with a continuous, walk-through gangway
  • Class 483: two cars, the classic quarter-train cut
  • No roof-mounted pantograph – current collector shoes sit on the side of the bogie

Updated: August 2026 – A large glazed front end, a continuous light strip and a train you can walk through across four cars: Classes 483 and 484 are the newest generation of the Berlin S-Bahn. This page shows how to tell the two-car and four-car units apart, why the two numbers belong together, and how to distinguish them from the older Berlin classes.

What are Class 483 and 484?

Classes 483 and 484 are electric multiple units of the Berlin S-Bahn from the same vehicle family, but built in two lengths: the 483 is a two-car unit equivalent to the classic quarter-train, and the 484 is a four-car unit you can walk through from end to end. Both run on 800 V DC from the side-mounted third rail and therefore carry no roof pantograph. They are operated by S-Bahn Berlin.

They build on Berlin’s basic principle and extend it in one place: two cars remain the smallest unit, but the four-car unit is the first to bundle four cars together with no break. For identification this means: unit length is a genuine feature here, whereas with the Class 481 / 482 and the Class 480 it is always two cars.

The Berlin classes side by side

Class Unit length Gangway within the unit Visual impression
480 2 cars no angular, older generation
481 / 482 2 cars no the network’s standard image
483 2 cars no modern, large glazed front end
484 4 cars yes, walk-through throughout modern, longer unit
485 / 885 2 cars no rounded older-build shape

The table makes the key point visible: between 483 and 484 the number of cars decides, between the modern and older classes the front-end design decides – and in any case of doubt, the vehicle number. The guide to identifying classes describes how to work through this checking order cleanly.

How to identify them in the field

Recognise the network

No pantograph, narrow car body, red-and-yellow livery: Berlin S-Bahn. Regional multiple units are ruled out immediately.

Count as far as the next driving cab

Two cars point to a two-car unit, four to the 484. Make sure you don't miss the gangway between two units.

Check the gangways

If you can walk through within the unit, it's the four-car type. Older Berlin classes don't offer that.

Read the number

483 or 484 on the car body settles the identification – regardless of how the train is made up.

Photographing a network in transition

A network where a new vehicle generation is replacing an old one is rewarding for photography – but only for a limited time. The same is currently true of the underground network of the Berliner Verkehrsbetriebe (BVG), where a new vehicle generation is also arriving.

The shot that won't be possible later

Photos with an old and a new class at the same station won't be reproducible in a few years' time. Such transitional images are more valuable than the hundredth clean single portrait – plan for them deliberately instead of hoping for luck.

Four points for practice:

  1. Large glazed areas reflect. An angle of 30 to 45 degrees to the vehicle axis reduces reflections and shows the front and side at once.
  2. Four-car units need space. A 484 is significantly longer than the familiar quarter-train – check your framing beforehand.
  3. Keep the number visible. Without a legible number, the identification stays uncertain in the archive.
  4. Keep a safe distance. Next to the track runs a live third rail; the track area is off limits without exception.

The guide to taking good photos of trains covers how to expose and sharpen your shots properly. To keep the pictures findable later, the article on building a photo archive for spotters is worth reading.

What the walk-through gangway changes in operation

For the Berlin S-Bahn, the four-car unit is more than just a longer vehicle. For decades the rule was: two cars, then a coupling, then two more cars. Passengers couldn’t walk through the train, and the vehicle technology was designed around this two-car split. With the 484, a continuous interior spanning four cars exists for the first time.

For you as an observer, this has several visible consequences:

  • Unit boundaries lie further apart. Anyone used to expecting a boundary every two cars will miscount on the four-car unit. Watch for the driving cab, not the rhythm of the cars.
  • The gangway is recognisable from outside. A bellows with a walk-through passage looks different from a simple coupling point between two units. This difference is visible even from several metres away.
  • Train formations become more varied. Different train lengths can be formed from two-car and four-car units. That makes counting more demanding and documentation more interesting.

Always count to the driving cab

The only reliable unit boundary is the driving cab. Bellows exist both within a unit and between two units – you can tell the coupling between units apart by the missing gangway and the extra front-end section.

For documentation it’s therefore worth noting the train’s composition: how many two-car and how many four-car units it contained. This detail doesn’t age and later makes it possible to trace how vehicle deployment on the network has developed – especially in a phase where new vehicles keep arriving and older ones keep disappearing.

Common mix-ups

It points to 483 / 484 if …

  • the vehicle number starts with 483 or 484
  • the front end is extensively glazed and carries a continuous light strip
  • you can walk through within a four-car unit
  • there's no pantograph on the roof

Look more closely if …

  • a train is made up of a mix of two-car and four-car units
  • you might be missing the unit boundary in a long train
  • the train is standing in the dark and only the light strip is visible
  • you can't reliably read 483 or 484 from a distance

It's not a 483 / 484 if …

  • a car carries the number 482 – then it's the 481
  • a car carries the number 885 – then it's the 485
  • both cars carry the same number 480
  • the unit is three cars long: that's the Hamburg build

How differently the same basic idea can turn out is shown by looking at the older Class 485 – the same train formation, a completely different design language.

One final point on context: new vehicle generations don’t arrive all at once but are rolled out over several years. During this time, old and new classes run side by side, sometimes even in mixed trains. Anyone who regularly visits the same station and logs their sightings with a date is documenting this transition almost as a side effect – and ends up with a time series that no report assembled after the fact can ever provide.

Conclusion

For Classes 483 and 484, exceptionally it isn’t the number alone that decides, but an observation you can make from twenty metres away: how many cars form a unit, and can you walk through it? Two cars with no gangway means 483, four cars with a gangway means 484. Everything else follows the familiar Berlin pattern.

In short

Modern front end, no overhead line, two or four cars per unit: that's the new Berlin S-Bahn. The walk-through gangway on the four-car unit is the one feature no older class on the network offers.

Summary

  • Classes 483 and 484 form the newest generation of the Berlin S-Bahn and are gradually replacing older classes.
  • The 483 is a two-car unit, the 484 a four-car unit with a walk-through gangway – that's the quickest distinction in the field.
  • Every other feature of the Berlin system stays the same: third rail, narrow loading gauge, trains formed from units.
  • Because the fleet is growing and older classes are disappearing, the picture on the network keeps changing – dated sightings are correspondingly valuable.

Frequently asked questions

What's the difference between Class 483 and Class 484?

The 483 is a two-car unit, equivalent to the classic Berlin quarter-train. The 484 is a four-car unit that you can walk through from end to end. Technically both belong to the same vehicle family; only the length and the cut differ.

Can you walk through the whole train on a Class 484?

Within a single four-car unit, yes – that's new for the Berlin S-Bahn. Between two coupled units there is still no walk-through gangway. When identifying a train, only count as far as the next driving cab, never across the whole train.

How do I recognise the new Berlin S-Bahn at a glance?

By the front end: it's extensively glazed and carries a continuous light strip, while older Berlin classes look markedly more angular and broken up. For a final confirmation, read the vehicle number on the car body.

Why don't these vehicles have a pantograph?

Because the Berlin S-Bahn runs on 800 V DC drawn from a side-mounted third rail. Instead of a roof pantograph, current collector shoes sit on the side of the bogies. All Berlin S-Bahn classes share this feature.

Do 483 and 484 replace the older classes?

The new vehicles are gradually taking over duties from older classes. How far this process has progressed and which lines are affected keeps changing with deliveries and service contracts. Always check the current status rather than relying on older overviews.

How many cars does a complete train have?

That depends on how it's made up. Different train lengths can be formed from two-car and four-car units. Total length is therefore useless for identifying the class – what matters is the length of the individual unit between two driving cabs.

What does the 94 in the vehicle number mean?

94 is the UIC type code for electric multiple units and railcars, and forms the first two digits of the twelve-digit number. It says nothing about the electrification system – only a look at the roof and bogie reveals whether it's overhead line or third rail.

Is it worth photographing the new vehicles now?

Yes, precisely because the network is in transition. Photos showing new and old classes standing side by side can never be recreated later. Keep the vehicle number legible in the frame and always keep a safe distance from the platform edge.
