Key takeaways
- Coradia Max is a product name, not a class – don't expect to see it marked on the vehicle.
- It's about double-deck vehicles: two decks, entrance set low.
- What matters is the class number on the vehicle; it's the only unambiguous identifier.
- The platform came into Alstom's portfolio via the Bombardier rail business takeover.
- What's actually delivered depends on the contract – consist, livery and operator all change.

- Two decks – the body is noticeably taller than on single-deck vehicles
- A characteristic narrowing of the body around the doors
- Entrances set low, with stairs leading up and down from there
- The product name doesn't appear on the vehicle – there you'll only find the class or coach number

Updated: August 2026 – Anyone searching for the Alstom Coradia Max is searching for a product name, not a class. It refers to double-deck vehicles from Alstom’s catalogue – and it almost never appears on the vehicle itself. This page explains what’s behind the designation, how to correctly place such vehicles in the field, and why the vehicle number always decides in the end.
Seen a product name, looking for the class?
Always note the vehicle number – it's the only identifier that still holds up later.
What’s behind the Alstom Coradia Max?
Coradia Max is a product designation from manufacturer Alstom for double-deck vehicles in passenger rail service. It belongs to the Coradia family, under which Alstom groups its vehicles for regional and local service – alongside names such as Coradia LINT, Coradia Continental or Coradia Stream.
Important for practice: this is not a German class designation. In Germany, rail vehicles are managed via class numbers, and it’s exactly those that appear on the vehicle. Product names are marketing and catalogue designations. They help in placing a vehicle family, but they aren’t what you should be looking for on the platform.
The double-deck vehicle families now carried under this name came into Alstom’s portfolio with the takeover of Bombardier Transportation’s rail business. That’s why there are technically related vehicles still running under older designations – such as the Bombardier Twindexx Express of Classes 445 and 446. Knowing this context lets you correctly place manufacturer names, instead of mistaking them for classes.
How to identify such vehicles in the field
Establish the number of decks
Two decks, a tall body, an entrance set low with stairs leading up and down: that's a double-deck vehicle. That already settles the vehicle category.
Clarify the drive question
Is a locomotive attached to the train? Then it's a loco-hauled train, often with a driving trailer at the other end. If the train runs without a locomotive, it's a multiple unit. That separates two quite different vehicle worlds.
Read the number
The class or coach number is shown on the side wall and in the data panel. It's the only way to a definite identification.
Note the operator
Livery and markings follow the customer. They change with tenders – so note them in your log, but they're of no use for class identification.
The systematic order for identifying vehicles is explained in the guide to identifying rolling-stock classes. Where the numbers appear on the vehicle is shown in the guide finding the train number.
Manufacturer name is not an identification feature
Product names like Coradia, FLIRT, Mireo or Desiro are useful for understanding vehicle families. For identifying a specific vehicle they're useless, because they're never marked anywhere on it. Get into the habit of always noting the number – not the name you read in a press release.
Placement: double-deck vehicles in German passenger service
Double-deck vehicles solve a simple problem: more seats over the same train length. That’s valuable wherever platforms can’t be extended indefinitely and demand is high. The table below places the different variants.
| Body style | Drive | Typical use | Recognition aid |
|---|---|---|---|
| Double-deck loco-hauled train | Locomotive on the train | Regional and long-distance service | separate locomotive, often a driving trailer at the end |
| Double-deck multiple unit | integrated into the train | Regional and Regional Express service | no locomotive, continuous train formation |
| Single-deck multiple unit | integrated into the train | Local and long-distance service | lower body, one deck |
| High-speed multiple unit | integrated into the train | Long-distance service | one deck, aerodynamic head shape |
In practice that means: the difference between local and long-distance service can’t be read from the number of decks – both exist in double-deck form. What really distinguishes the types of service is covered in the article on local versus long-distance service from a spotter’s perspective. A single-deck counterexample from the long-distance world is the ICE 4 of Class 412; another double-deck concept is Class 462.
Number instead of product name
A log that contains vehicle numbers is still usable in ten years' time. Marketing names aren't.
Spotting and photo tips for double-deck vehicles
Double-deck trains are more demanding to photograph than they look. The tall body noticeably changes perspective and lighting.
- Plan for more distance. From close up, the tall body tips strongly backwards in the frame. Greater distance with a longer focal length looks calmer.
- Look for a higher viewpoint. From a slightly elevated, publicly accessible spot, the upper deck can be shown better. Accessible footbridges are the classic place for this.
- Keep the number legible. For record shots, a crop that keeps the data panel sharp makes sense.
- Document both ends of the train. With loco-hauled trains that have a driving trailer, the two ends look completely different – one shot isn’t enough.
The photographic basics are covered in the guide to good train photos; properly recording the data is covered in the article on the sightings log.
Safe distance and slipstream
Even on platforms without high-speed traffic: passing trains create a pressure wave followed by a pull towards the track. At high speeds it's enough to knock people off balance and pull loose equipment along with it. Stay consistently behind the safety line and secure your tripod and bags. Track areas, operational railway land and stabling sidings are private land and not a permitted photo spot. The rules are set out in the guide to safe distance from the track.
Product names, classes, and why both exist
The confusion between manufacturer names and class designations isn’t unique to the Coradia Max. It runs through the entire modern vehicle fleet – and there’s an understandable reason for it.
Manufacturers think in platforms. A vehicle concept is developed once and then adapted for many customers: different length, different door layout, different certification. The product name keeps this relationship together and serves sales.
Railways think in classes. For operation, maintenance and certification, an unambiguous identifier is needed for each vehicle type and each individual vehicle. That’s exactly what the class number provides, supplemented by the twelve-digit vehicle number with its UIC type code in the first two positions.
For you as an observer, a clear division of labour follows:
- The product name helps with understanding. It tells you which vehicle family you’re dealing with and which related vehicles exist.
- The class number helps with identification. It’s marked, unambiguous and permanent.
- The livery helps with neither. It follows the customer and changes with every new tender.
Anyone who gets into the habit of always recording the number sidesteps the problem entirely – regardless of what a manufacturer currently calls its product line.
Common mix-ups
The classification fits if …
- the train has two decks
- the entrance sits low with stairs leading up and down
- the markings show a German class number
- you've noted that number
Look more closely if …
- you want to adopt a product name from a report without having checked the number
- the train is running in an unfamiliar livery
- you're not sure whether a locomotive is attached to the train
It doesn't fit if …
- the train has only one deck
- it's a high-speed multiple unit with an aerodynamic head shape
- the number clearly belongs to a different vehicle family
Conclusion
The Alstom Coradia Max is a good example of why product names and class designations aren’t the same thing. The name describes a double-deck vehicle family from Alstom’s catalogue; you won’t find it on the vehicle. Anyone working properly determines the body style – two decks, drive on board or a locomotive in front – and then reads the vehicle number. That’s the information that still holds true even after brands, operators and liveries have long since changed.
In short
Coradia Max is a product name for double-deck vehicles, not a class. Identify it by body style and drive type – and always note the vehicle number, because only that is unambiguous.
Sightings that still hold up tomorrow
Vehicle number, date, location and operator in one place – that's how observation becomes a reliable archive.
Summary
- Coradia Max is the product designation under which Alstom markets double-deck vehicles for passenger service.
- For identification in the field the name is of little use, because it doesn't appear on the vehicle.
- What matters is the body style – two decks, entrance set low – and the class number.
- Operator, livery and train formation depend on the specific contract and change with each tender.
Frequently asked questions
What is the Alstom Coradia Max?
Coradia Max is a product designation by Alstom for double-deck vehicles in passenger rail service. It belongs to the Coradia family, under which Alstom bundles its vehicles for regional and local service. It's not a German class designation but a name from the manufacturer's product catalogue.
Does Coradia Max appear on the vehicle?
As a rule, no. On the vehicle you'll find the class or coach number, along with the operator's markings. Manufacturer product names show up, at best, in press releases and data sheets. For identification in the field, the number is therefore the only reliable way.
How do I recognise a double-deck vehicle from this family?
By its body style: two decks, a noticeably taller body, and the typical narrowing around the doors. The entrance sits low, with stairs leading up to the upper deck and down to the lower deck from there. Which specific class results from that is only revealed by the number on the vehicle.
Why is this train listed under type code 93?
The first two digits of the twelve-digit vehicle number make up the UIC type code, which describes the vehicle type. In this database the entry is filed under 93. For practical identification, what matters more is which number is actually shown on the vehicle – that's the decisive reference point.
How does Coradia Max relate to Bombardier?
The double-deck vehicle families now carried under this name originate from the rail business of Bombardier, which Alstom took over. Product names were then folded into Alstom's system. Older vehicles therefore still carry designations from the Bombardier era, even though they technically belong to the same line.
Do these vehicles run in local or long-distance service?
Double-deck vehicles of this design are found in both areas: in regional service as well as in double-deck long-distance service. Which variant is deployed where depends on the specific contract and changes with tenders and timetable years.
How do I find out exactly which class is in front of me?
Via the vehicle number. It's shown on the side wall and in the data panel and assigns the vehicle unambiguously to a class. Note it in full – with class number and running number. Only then is a sighting verifiable and usable later.
Are double-deck trains and double-deck multiple units the same thing?
No. A double-deck loco-hauled train is pulled by a locomotive and often has a driving trailer at the other end. A double-deck multiple unit carries its own traction equipment on board. Both exist in double-deck form – to tell them apart, always check whether a separate locomotive is attached to the train.

Who is behind it
Groups, brands, manufacturers and operators – who owns whom and how to recognise them out in the field.
Alstom
After taking over Bombardier Transportation, Alstom is Europe's broadest vehicle manufacturer. Diesel railcars, freight locomotives, trams – much of it comes from the same house, recognisable not by the logo but by the platform names and their body styles.
ManufacturerBombardier Transportation
Bombardier Transportation was for decades one of Europe's largest rolling stock manufacturers, with plants in Hennigsdorf, Görlitz and Bautzen. Since 2021 the company has been absorbed into Alstom. The product names TRAXX, Talent and Twindexx live on – the company name on the vehicle, however, is history.
