Key takeaways
- The Mireo is Siemens' modern regional multiple unit platform and runs in Germany under several class numbers, including 463, 464, 563 and 1463.
- Four-digit class numbers such as 1463 arise when the three-digit base block is already assigned.
- Fastest way to identify it: articulated train with Jacobs bogies, very flat and smooth front, large side windows.
- Risk of confusion exists with the FLIRT and Coradia Continental – all three are aluminium-built articulated trains of the same size class.
- Network and operator are changeable and don't work as an identifying feature.

Updated: August 2026 – Flat front, smooth aluminium skin, barely visible roof fittings: the Siemens Mireo belongs to the newest generation of German regional multiple units, and the Class 1463 is one of the number groups under which it runs. This page shows how to recognise it and how to tell it apart from the FLIRT, Coradia and Desiro.
Spotted a Mireo? Note the full number.
With modern multiple units, the number is the only unambiguous identifier – Traintrack stores it along with location and date.
What is the Class 1463?
The Class 1463 denotes units from Siemens’ Mireo family – electric multiple units for regional service. They’re built as articulated trains with Jacobs bogies, have a lightweight aluminium body shell, run on 15 kV / 16.7 Hz AC and are designed for 160 km/h.
The Mireo is laid out as a modular platform: the number of body sections and parts of the equipment vary depending on the order. That’s exactly why it appears in Germany under several class numbers – alongside 1463, among others as Class 463/464 and as Class 563. For spotters that means: family and class aren’t the same thing. In everyday life you’ll encounter Mireo units under network brands such as the S-Bahn Rhein-Neckar anyway.
How to pin down the Mireo
Modern multiple units differ less in large body shapes than in details. Even so, there’s a reliable order in which you can proceed.
Count the bogies
If only one bogie sits between two body sections, it's an articulated train. That immediately rules out all conventionally built trains.
Assess the front
The Mireo looks slim and smoothly rounded, with a wide windscreen and flush-mounted lights. More angular fronts point more towards a FLIRT.
Look at the side windows
Large, high-set windows and a lightly panelled aluminium side wall are typical. Strong ribs and steps point to other families.
Read the number
Only the vehicle number decides. If it starts with 1463, the identification is unambiguous – everything before that is a probability estimate.
The system behind the twelve-digit number – from the design code 94 to the check digit – is explained in the guide to the UIC number. The general order of operations for identifying classes is given by the guide to identifying classes.
Where it fits into railway operations
Regional multiple units of this class replace locomotive-hauled local trains: traction is distributed across the train, acceleration from a stop is better, and turning round doesn’t require shunting. Such vehicles are ordered and financed by transport authorities such as the Nahverkehrsgesellschaft Baden-Württemberg. For observation this results in a clear pattern.
| Location | Chance of a sighting | Why |
|---|---|---|
| Electrified regional lines in clockface service | high | Core area of use for this vehicle generation |
| Terminal stations with turnaround time | high | The train stands long enough for clean pictures and the number |
| Major hub stations | medium | Lots of traffic, but short stops and often difficult light |
| Long-distance routes without local stops | low | No scheduled use |
| Non-electrified branch lines | very low | No use without a contact wire – diesel or battery vehicles run there instead |
Network information is a snapshot
Which operator runs which vehicles in which network is tied to service contracts. After a new award, entire fleets change region, colour and markings. So always take the current status – via real-time information and current community sightings.
Report a sighting before it's forgotten
Number, location, date – logged in Traintrack in seconds and useable for good.
Spotting and photo tips
The Mireo is a rewarding but restrained subject: lots of smooth surface, little structure. Anyone who only photographs it head-on gets interchangeable pictures.
Three-quarter view as the default
Around 30 to 45 degrees off the vehicle axis shows front and side wall at once. With very flat fronts, that's the difference between three-dimensional and flat.
Use raking light
Low sun brings out ribs, door gaps and the roof edge. Hard midday light makes aluminium surfaces look featureless.
Whole unit or nothing
With articulated trains, the full silhouette tells the body design. If the length doesn't fit in the frame, deliberately show a joint with a Jacobs bogie instead.
Number as a mandatory shot
A second, tight picture of the side markings makes every sighting solid – even if the main picture is composed more artistically.
Platform edge and track area
Photography happens behind the safety line, not in front of it. Track areas, operational railway land and sidings are off limits – that's not a formality, it's the condition for keeping the hobby trouble-free.
How to record a sighting so it stays useful for others later is described in the guide to reporting sightings.
Platform rather than single class: why that makes identification harder
A class number used to stand fairly reliably for a particular vehicle type. With modern multiple units that’s different. Manufacturers develop platforms, from which they build different configurations depending on the order: more or fewer body sections, different step-in height, different equipment, sometimes a different drive type. The Mireo is a textbook example of this.
That leads to a situation you have to get used to: one family, many class numbers. Two trains can look identical at first glance and still belong to different number groups because they come from different orders. Conversely, two units of the same class number can differ in details of interior fit-out.
For practical purposes that means three things. First: recognising the family is valuable, but not the same as determining the class. Second: the full vehicle number isn’t optional, but the only route to unambiguous identification. Third: features such as livery, destination boards or network names are pure snapshots and never work as a basis for identification.
Practical tip for platform vehicles
Get into the habit of always taking a second picture of just the side markings on modern multiple units. When reviewing the pictures in the evening, that lets you reconstruct the unit even if the main picture doesn't show the number legibly.
Common mix-ups
Several aluminium-built articulated trains run in the same size class. Realistic candidates are the Coradia Continental as Class 1440, the FLIRT as Class 428, and – at a fleeting glance – the Desiro HC as Class 2462, although that one has a double-deck intermediate car.
It points to a Mireo when …
- the train is an articulated train with Jacobs bogies
- the front looks very flat and smoothly rounded
- the side windows are large and sit high
- the vehicle number comes from a Mireo block such as 463, 464, 563 or 1463
Look more closely when …
- the end bogies sit noticeably short and far outboard – hint of a FLIRT
- the front is rounder and the side wall more strongly panelled – hint of a Coradia
- the train carries additional large roof fittings – then a battery variant comes into play
It isn't a Mireo when …
- intermediate cars are double-deck – that's the pattern of the Desiro HC
- a separate locomotive is moving the train
- two separate bogies sit between the body sections instead of one
Verdict
The Class 1463 stands for the current generation of electric regional multiple units: light, smooth, typically articulated – and with a number that reveals more about the German class system than about the vehicle. Anyone checking body shape, nose shape and number in that order is almost always right, and the full vehicle number turns a guess into a solid sighting.
In short
Articulated train with Jacobs bogies, very flat smooth front, large high side windows: that's the Mireo look. The four-digit 1463 additionally tells you that the three-digit block was already taken.
Your multiple-unit collection keeps growing
Every logged number sharpens your own statistics – and shows which units you're still missing.
Summary
- The Class 1463 is one of the number groups under which the Siemens Mireo runs in Germany.
- Technically it is an electric articulated train in lightweight aluminium construction for 160 km/h.
- It can be told apart from the FLIRT and Coradia via nose shape and window layout – reliably only via the vehicle number.
- Where the train runs is decided by service contracts; for lasting statements only the vehicle number itself is any use.
Frequently asked questions
What is the Siemens Mireo?
A modular platform for electric regional multiple units from Siemens. It's built as an articulated train with Jacobs bogies and an aluminium body shell and can be built with a varying number of body sections. In Germany, Mireo units carry several class numbers, including 463, 464, 563 and 1463.
Why does the Mireo have a four-digit class?
Because the three-digit number blocks are limited. Once a block is taken, a digit is placed in front of it: 463 becomes 1463. The same logic explains classes such as 1440 for the Coradia Continental or 2462 and 3462 for the Desiro HC.
How do I tell a Mireo apart from a FLIRT?
The FLIRT has short, far-outboard powered bogies under the end cars and a more angular, more strongly wraparound windscreen. The Mireo looks slimmer, the front is flatter and more smoothly rounded, and the side windows sit higher. Only the vehicle number separates them reliably.
What does the design code 94 mean?
The first two digits of the twelve-digit UIC vehicle number give the design. 94 stands for electric multiple units and railcars. A diesel railcar would carry 95, an electric locomotive 91. The code says nothing about manufacturer, number of body sections or operating area.
How fast does the Class 1463 run?
The maximum speed is 160 km/h. That keeps the train able to keep pace on mixed-traffic main lines without holding up the rest of the traffic. In dense local service, the sequence of stops decides the actual travelling speed.
Is there a Mireo without overhead wire too?
Yes. The platform also exists as a battery-electric variant that bridges short non-electrified sections from the battery. Such vehicles carry their own class numbers and can be recognised by additional roof fittings for the energy storage.
Where does the Class 1463 run?
That changes. Regional multiple units run under time-limited service contracts; after a new award, network, operator and often the livery change too. Rely on current real-time data and sightings rather than older network overviews.
What is a Jacobs bogie and why does it matter?
It's a bogie shared by two neighbouring body sections. Only one bogie sits at the join, instead of two. For identification purposes that's worth gold: counting bogies along the train tells you immediately whether you're looking at an articulated train or a conventional one.
