Key takeaways
- The 450 is not an everyday class: finding it takes local and timing knowledge, not general timetable reading.
- The 45x block isn't used consistently – neighbouring numbers belong to very different vehicles.
- The full number decides: a three-digit and a four-digit class part are two different things.
- Type code 94 classifies the vehicle as an electric multiple unit before the class even comes into play.
- No claims without evidence: for classes this sparsely documented, no estimated numbers built or performance figures are given.

Identifying features
Is this really the class in front of you?
- The twelve-digit vehicle number starts with 94 for electric multiple units
- The class part of the number reads 450 – three digits, not four
- Check the type of current pickup: roof pantograph or side-mounted collector shoe
- Count the number of car sections per unit, up to the next pair of driving cabs
- Note the gangway design: one shared bogie or two separate ones
- Note the route: pure railway operation or mixed operation with tram lines
Updated: August 2026 – Not every class number belongs to a vehicle you see on the way to work. The Class 450 is such a case: a number from the block of electric power and intermediate cars, for which there’s no broad, well-established everyday knowledge. This page therefore doesn’t claim anything it can’t back up – instead, it shows you how to properly classify a vehicle with this number in the field.
A rare sighting? Then document it properly.
With unusual classes especially, every detail counts: number, location, date, photo – all in one place in Traintrack.
What’s behind the Class 450?
The Class 450 is a number from the German class block 4xx, reserved for electric power, intermediate and driving trailer cars. The associated UIC type code is 94, which stands uniformly Europe-wide for electric multiple units and railcars. That settles the broad vehicle type before any detail even comes into play.
What this number does not provide, however, is a reliable picture of the vehicle. The 45x range is used inconsistently in the German scheme, and some numbers cover only small fleets or borderline cases that are poorly documented in public. Anyone throwing around numbers built, build years or performance figures they can’t back up produces misinformation. This page therefore deliberately avoids such claims.
A look at the immediate neighbourhood shows how inconsistent the block is: the Class 0450 (Bombardier Flexity Link) designates a dual-system light rail vehicle that switches between the railway and tram network – a completely different vehicle concept from a classic regional multiple unit, yet classified in the same number range.
The safe route: observe first, then read the number
For rare or unclear classes, the route never runs via guesswork, but via a fixed chain of observation.
Determine the vehicle type
Multiple unit or locomotive-hauled train? Electric or internal combustion? This first fork decides the entire number range that can even be in question.
Check the current pickup
A roof pantograph means overhead line. Side-mounted collector shoes on the bogies mean DC via a side-mounted conductor rail. The two generally rule each other out.
Record the structure
How many car sections does a unit have up to the next pair of driving cabs? How many bogies sit at the gangways? Note both, even if you don't yet know the class.
Read the number in full
Only now look for the twelve-digit vehicle number and note it completely – including the number of digits in the class part.
Why this order and not the reverse? Because memory likes to fit images to familiar patterns. Anyone who reads a number first and only then looks at the vehicle ends up seeing what they expect. The full system is set out in the guide to identifying classes; the structure of the number is explained in the article on the UIC number.
No estimated figures
Surprisingly precise-looking figures circulate online for sparsely documented classes, figures that can't be backed up. Don't adopt them. A sighting with a correct number and honest uncertainty is worth more than a second-hand data sheet.
What the number actually tells you
It helps to keep the levels of information cleanly separated. This table shows what you can rely on and what you can’t.
| Level | Example | Reliability | Note |
|---|---|---|---|
| UIC type code | 94 | very high | uniform Europe-wide, marked on the vehicle |
| Number block | 4xx | high | electric power and intermediate cars |
| Class part | 450 | high, if read in full | three- and four-digit numbers differ |
| Running number | varies | high | identifies the individual unit |
| Manufacturer, build year, numbers built | – | often low | for rare classes, use only with evidence |
| Operator, network, livery | varies | low | changes with contract awards and timetable years |
The bottom two rows are why experienced spotters base their sightings on numbers rather than appearance. How to report a sighting so others can follow it is described in the guide to reporting sightings.
Unsure sighting? Log it anyway.
Note what you saw and flag any uncertainty – everything can be corrected later, nothing can be invented after the fact.
Borderline cases between railway and light rail
Part of the confusion in the 45x range arises where vehicles shuttle between two worlds. Dual-system light rail vehicles run on railway lines and on urban tram tracks. They therefore carry a vehicle number under the railway scheme, but look like a tram.
For identification, that means:
- The route is a feature. A vehicle that runs on the street and then switches onto a railway line belongs in this category.
- The build height reveals a lot. Light rail vehicles are lower, more finely articulated, and often have more but narrower doors than railway multiple units.
- Two power systems are possible. Some of these vehicles can handle both DC and AC; that’s barely detectable in the field, though.
- The number remains decisive. Even in borderline cases, the twelve-digit vehicle number is the only reliable identifier.
Classic electric local-service multiple units such as the Class 420 / 421 are clearly distinct from this: pure railway operation, larger vehicle dimensions, overhead-line operation.
Safety: extra care with mixed operation
Where railway and light rail operation meet, the rules aren’t identical – but the hazards are real.
- The platform edge and safety line always apply. Incoming vehicles create a slipstream and have no way to swerve.
- The track area is off-limits. Tracks, operational facilities and sidings are railway premises, regardless of how accessible they look.
- Side-mounted conductor rails are life-threatening. In DC networks with a conductor rail, the rail alongside the track stays permanently energised, even when no vehicle is in sight.
- Road traffic rules apply on the street. Anyone photographing a light rail vehicle on the street is standing in live traffic – with all the consequences that entails.
Common mix-ups
You're on the right track if …
- the vehicle number starts with 94
- you've read the class part in full
- you've noted the number of cars and the type of current pickup
- you have a photo of the side wall with a legible number
Look more closely if …
- the number might have a leading digit – 450 and 0450 aren't the same
- the vehicle looks like a tram but runs on railway tracks
- you want to infer the classification from a livery or a logo
It's not the 450 if …
- the class part shows a different number, even with a similar digit sequence
- the type code at the start of the number isn't 94
- you're relying solely on a memory rather than a number you actually read
Related numbers from the same block can be found on the pages for the Class 452 and the Class 455 – the same applies there too: observe the structure, read the number, don’t make anything up.
Conclusion
The Class 450 is a good example of how an honest page sometimes claims less than a poor one. What’s certain is the framework: type code 94, the number block of electric power and intermediate cars, an inconsistently used 45x range with borderline cases between railway and light rail. Everything else belongs to the vehicle itself – and that’s best checked yourself, with a fully read number and a photo that makes the classification verifiable.
Quick verdict
Type code 94, number block 4xx, three-digit class part 450: that's as much as can seriously be said without the actual vehicle in front of you. That's exactly why the full vehicle number matters more here than for any everyday class.

Summary
- The Class 450 belongs to the number range for electric power and intermediate cars, but it isn't a nationwide everyday vehicle.
- For a reliable classification, there's no way around the full twelve-digit vehicle number.
- The 45x range is used inconsistently, which especially causes misclassification at the borderline between railway and light rail.
- Anyone spotting a rare class should log number, location, date and a photo of the side wall – guesswork helps no one.
Frequently asked questions
What is the Class 450?
The Class 450 is a number from the German class block for electric power and intermediate cars. Unlike the major regional and S-Bahn classes, it's not a nationwide everyday vehicle. Reliable public detail is correspondingly thin – this page therefore focuses on the safe way to identify it rather than on claims.
How do I safely classify a vehicle numbered 450?
Via the full twelve-digit vehicle number. For electric multiple units it starts with type code 94, followed by the country code, class, running number and check digit. Add the number of car sections, the type of current pickup and the gangway design to your observation – that gives you a verifiable sighting.
Why can I find so little reliable information on the Class 450?
Because not every class number belongs to a large, well-documented fleet. Small series, special vehicles and borderline cases between railway and light rail are often only fragmentarily described in public. Invented numbers built or performance figures would be worse in such cases than an honest gap.
What does the 4xx number block mean?
In the German class scheme it's assigned to electric power, intermediate and driving trailer cars. S-Bahn vehicles, regional multiple units and special cases sit side by side within this block. The numbers are assigned sequentially and not sorted by build type or manufacturer – so neighbouring numbers say nothing about similar vehicles.
What does the 94 at the start of the vehicle number stand for?
The first two digits of the twelve-digit UIC number are the type code. 94 marks an electric multiple unit or railcar. This code applies uniformly Europe-wide and classifies a vehicle before you even get to the national class. It's therefore the most robust piece of information on the whole vehicle.
What's the difference between 450 and 0450?
The number of digits. A three-digit class like 450 and a number written with a leading digit like 0450 belong to different entries in the vehicle fleet. On a blurry photo, that looks almost the same – so always read the number in full, rather than only catching the last three digits.
How do I report a sighting I'm unsure about?
Note what you actually observed: the number, as far as legible, the number of car sections, the type of current pickup, location and date. A photo of the side wall is worth more than any guess. A sighting honestly marked as uncertain is more useful to everyone than a wrong classification that nobody corrects later.
How do I tell whether a vehicle is built for conductor rail or overhead line?
By the roof and the bogies. A pantograph on the roof means overhead-line operation. Side-mounted collector shoes on the bogies point to a DC system with a side-mounted conductor rail, as used by the S-Bahn networks in Berlin and Hamburg. The two systems generally rule each other out.
