Key takeaways

  • The TW 2000 is Hanover's Silberpfeil: unpainted aluminium, round front, procured at the end of the 1990s.
  • The car number is the type: 2001 onwards are two-section cars, 2501 onwards the three-section TW 2500 variant.
  • High floor instead of low floor: the Hanover Stadtbahn runs with high platforms – that sets it apart from classic tram networks.
  • There's a risk of confusion with the TW 3000, which continues the design language but is younger and detailed differently.
  • Deployment and fleet numbers change with route changes and the arrival of new vehicles.

Identifying features

Is this really the class in front of you?

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

  • Unpainted, shiny silver aluminium body – unmistakable on the network
  • Strongly rounded front end with a large, curved windscreen
  • High-floor vehicle: step-free boarding at high platforms, via fold-out steps at low stops
  • Car number begins with 20 (two-section) or 25 (three-section)
  • Often runs in double or triple formation, with a coupler between the units
  • Operates on a mixed system of tunnel sections and surface sections

Updated: August 2026 – Bare aluminium, an almost sculptural round front, plus high platforms instead of street-level boarding: the TW 2000 is one of the few local transport vehicles in Germany that you can recognise beyond any doubt from a hundred metres away. This page explains what’s behind the Silberpfeil (“Silver Arrow”), how to tell the two-section and three-section cars apart, and where the line with the younger TW 3000 runs.

Spotted a Silberpfeil? Note the number.

On Hanover's light rail cars, the car number doubles as the type identifier – ideal for a clean sighting.

What is the TW 2000?

The TW 2000 is a high-floor light rail car of the Stadtbahn Hannover, procured in the second half of the 1990s in the run-up to EXPO 2000. Its most striking feature is the unpainted aluminium body, which earned it the nickname Silberpfeil.

The vehicle family consists of two versions: the two-section TW 2000 and the three-section TW 2500. Technically the two belong together; they are used together and can be coupled into longer trains. You can tell them apart by the car length – and even faster by the number block.

The car number is the type

In Hanover a rule applies that makes identification unusually easy: the number block corresponds to the type.

Number block Type Feature
from 2001 TW 2000 two-section, silver aluminium body
from 2501 TW 2500 three-section, same design language
from 3001 TW 3000 youngest generation, modern front details
from 6001 TW 6000 older generation, angular design language

This clearly distinguishes Hanover from networks where vehicle types and car numbers are assigned independently of each other. If you can read the number, you only need the shape analysis as a cross-check. How systematic identification works in principle is described in the guide to identifying classes.

Number first, shape afterwards

With Hanover's light rail cars, the reverse order pays off: first read the car number on the front, then check the shape and number of sections as confirmation. That saves time when a train only stops briefly.

Stadtbahn means: neither tram nor underground

The Stadtbahn Hannover operates under BOStrab (the German tram regulations), but uses tunnel sections in the city centre and mostly segregated track further out. The vehicles are designed for high platforms; at stops without high platforms, fold-out steps help with boarding.

For observers this has several consequences:

  • High floor instead of low floor. Unlike modern trams, the vehicle floor sits high. That’s the quickest dividing line from low-floor networks such as those in Leipzig or Dresden.
  • Tunnel and surface in the same diagram. A vehicle switches between underground stations and surface sections within a single journey.
  • Trains made up of several units. Capacity is controlled by the number of coupled vehicles, not by single vehicles of different lengths.

Conceptually, the Stadtbahn is therefore closer to underground vehicles such as Hamburg’s DT5 than to classic tramcars. Where exactly the system boundaries lie in German public transport is explained in the article local and long-distance services compared.

Keep track of the fleet

Record car numbers systematically – and you'll see which vehicles on the network you're still missing.

Reading train lengths: one unit or several?

Because capacity in Hanover is controlled via coupled units, train length isn’t a feature of the type – it’s a feature of the time of day. One and the same type runs as a triple formation in the rush hour and on its own in the evening. If you don’t take that into account, you’re guaranteed to miscount.

Here’s how to go about it:

Count the driver’s cabs. Each unit has a driving position at both ends. Two fronts back to back in the middle of the train mean: this is where one unit ends and the next begins.

Look for the coupler. Between two units there’s a coupler, not a gangway bellows. The connection can’t be walked through – passengers can’t change cars there.

Note the car numbers separately. A train made up of three units has three numbers. For a clean sighting, all three belong in the record, not just the leading vehicle’s.

Distinguish two-section and three-section cars. Within a unit, the number of sections tells you whether you have a TW 2000 or a TW 2500 in front of you. That boundary runs within the unit; the coupler boundary runs between units.

Define the unit first, then identify

The order is crucial: first work out where a unit begins and ends. Only then count the sections within that unit. If you do it the other way round, you add up sections across two vehicles and end up with a type that doesn't exist.

Incidentally, the same logic applies to all local transport vehicles that run in multiple – from the S-Bahn to the tram.

Photo tips for the Silberpfeil

An unpainted aluminium body is demanding to photograph: it reflects its surroundings, shows every dent and completely changes its look depending on the angle of the light.

Prefer soft light

Light cloud is often better for bare metal than blazing sun. Direct midday light produces glaring reflections without detail.

Watch the reflections

The body reflects façades, sky and trees. Moving just a few metres changes the picture considerably.

Emphasise the round front

The design language lives from its curves. A three-quarter view from a slightly lower perspective shows them off better than a head-on shot.

Tunnel stations with care

Underground it's dark, high in contrast and cramped. Higher ISO values and calm positions at the end of the platform are the practical approach here.

Platform edge and track area

Space is tight at tunnel platforms in particular. Consistently keep a safe distance from the platform edge and never enter the track area under any circumstances. Flash aimed at the driver's cab is off limits.

For the special lighting conditions in tunnels, the guide to underground photography is worth a look. How to record sightings so that they can still be analysed years later is shown in the article on the sightings log.

Common mix-ups

The only realistic mix-up on its own network is the TW 3000: it deliberately continues the Silberpfeil’s design line, but is the younger generation with different front details and modern lighting. It was built by a consortium led by HeiterBlick. The electrical equipment comes from Kiepe Electric. The older TW 6000, by contrast, stands out immediately – angular design language, a completely different front.

It points to the TW 2000 if …

  • the body looks silver and unpainted
  • the front is strongly rounded with a large curved windscreen
  • the car number begins with 20 or 25
  • the vehicle runs on the Hanover Stadtbahn network

Look more closely if …

  • the design language fits but the front details look more modern – then check for a TW 3000
  • an advertising wrap covers the silver body
  • several units are running coupled and you misread the train length

It's not a TW 2000 if …

  • the car number begins with 30 or 60
  • the vehicle has low, step-free boarding at street level
  • a twelve-digit vehicle number is displayed

Conclusion

The TW 2000 is one of the few German local transport vehicles with genuine recognition value – and at the same time one of the easiest to identify, because the car number directly supplies the type. It remains interesting because, as a vehicle generation, it is now getting on in years and is gradually being joined by younger stock. The Stadtbahn’s retired predecessor generations are preserved at the Hannoversches Straßenbahn-Museum.

In short

Silver aluminium body, round front, number from 2001 or 2501: that's the TW 2000 or TW 2500. The only serious risk of confusion is with the younger TW 3000 – the number decides.

Summary

  • The TW 2000 is Hanover's silver light rail car and has shaped the look of the network since the late 1990s.
  • It exists as a two-section and a three-section version, distinguishable by car length and number block.
  • As a high-floor vehicle it differs fundamentally from the low-floor trams of other German cities.
  • Distinguishing it from the younger TW 3000 works via the front, the lighting and the number block.

Frequently asked questions

Why is the TW 2000 called Silberpfeil?

Because of its unpainted aluminium body. Instead of a paint finish, the vehicle shows the bare metal surface, which gives it a characteristic appearance in sunlight. Together with the strongly rounded front, this makes the vehicle visually unmistakable in German local transport. Silberpfeil means “Silver Arrow”.

What is the difference between the TW 2000 and the TW 2500?

The number of car sections. The TW 2000 has two sections, the TW 2500 three, and is correspondingly longer. Technically both belong to the same vehicle family and are used together. The quickest way to tell them apart is by the car number: 2001 onwards versus 2501 onwards.

Is the Hanover Stadtbahn a tram or an underground railway?

It is a light rail (Stadtbahn) system: operated under BOStrab, but with tunnel sections in the city centre and surface sections further out. The vehicles are designed for high platforms. That places it between a classic tram and an underground railway – which also explains the vehicle design.

How do I tell the TW 2000 apart from the TW 3000?

Both continue the same design line, but the TW 3000 is the younger generation with modern LED lighting and differently styled front details. The unambiguous feature is the car number: numbers from 3001 belong to the TW 3000, numbers from 2001 or 2501 to the TW 2000 or TW 2500 respectively.

Does the TW 2000 have a UIC number?

No. Type code 94 for electric traction units comes from the railway's twelve-digit numbering system. Light rail and tram vehicles operate under BOStrab and carry an operational car number – on the Hanover vehicles, it's exactly this number that is also the best identification feature.

Why do the cars often run coupled?

Because that lets capacity be matched to demand. Two or three units are coupled into one train and separated again at off-peak times. For identification that means: count the driver's cabs. Two fronts back to back mean two vehicles, not one longer one.

Where is a good place to watch the TW 2000?

On the surface sections of the network and at termini, where vehicles stand and turn. In the tunnel sections, photography is considerably more difficult because of the lighting conditions and the cramped platforms. Which lines get which stock changes constantly.
