Key takeaways
- The 225 isn't its own new-build class: it was created from Class 215 locomotives that lost their train heating.
- No train heating means freight locomotive. That's exactly what the new class number expresses, without the vehicle changing much on the outside.
- Visually it belongs to the V 160 family: four axles, closed body, cab at both ends, roof-mounted radiator.
- The number is the only reliable feature against the 215 and 218 – body shape and wheel arrangement are identical.
- Keeper and use keep changing: many locomotives today stand with construction firms and private freight operators.

Updated: August 2026 – The Class 225 is a good example of how a German class number describes not just the design, but also what a vehicle may be used for. Visually it belongs to the well-known V 160 family, operationally it’s a pure freight locomotive. This page explains how that came about and how you can identify it.

What is the Class 225?
The Class 225 is a four-axle diesel-hydraulic main-line locomotive for freight traffic, created from Class 215 locomotives that lost their train heating. Wheel arrangement B’B’, maximum speed 140 km/h, closed body with a cab at both ends.
The step was purely operational: locomotives that only worked freight trains any more didn’t need heating equipment. Without it they’re lighter, simpler to maintain – and no longer passenger locomotives. The class system reflects this change of purpose with a number of its own.
How the German class system reflects rebuilds
Anyone who only compares vehicles doesn’t understand the 225. You need to know the logic behind the numbers.
Since 1968, German railways have worked with three-digit class numbers. The range 200 to 299 belongs to diesel locomotives, with main-line locomotives sitting in the lower groups and shunting and small locomotives further up. Within this framework, a new number isn’t only assigned for new designs, but also when something operationally relevant changes on existing vehicles:
- Train heating removed – the 215 becomes the 225.
- New engine fitted – the 219 becomes the 229, the 232 becomes the 233 and the 241.
- Cleared speed changed – that too can justify a new class.
For you in the field, that means: the number tells you more about a vehicle than its looks. Two visually identical locomotives can belong to different classes, and conversely, vehicles of the same class can differ noticeably in detail, for example through retrofitted train protection, changed front lighting, or different buffer and frame designs. The guide to identifying classes explains how to find and read vehicle numbers quickly and correctly.
The historical background matters too: the Bundesbahn, from which Deutsche Bahn AG emerged in 1994, named diesel locomotives up to 1968 with a leading V and a number that roughly indicated the power class – V 60, V 100, V 160, V 200. In 1968 it switched to the three-digit scheme that still applies today. Vehicles that only came about after this switch therefore carry a purely numeric designation from the start, while older classes have two names. The 225 belongs to the second generation of this system: it never ran under a V designation, but is the result of a later operational reclassification.
How to identify a 225 in the field
Establish the family
Four axles in two bogies, a continuous body, a cab at both ends, a radiator on the roof: that's the V 160 family.
Check the train formation
If a freight, engineering or transfer train is coupled behind, that points to a heating-less variant. A clue, not proof.
Read the number
This is the only reliable way to decide between 225, 215 and 218. Front, side wall and UIC markings show it.
Note the keeper markings
For private owners, they reveal who currently runs the machine – often more telling than the livery.
Practical tip: train formation as a pre-filter
If you see a locomotive of the V 160 family in front of tank wagons, ballast hoppers or an engineering train, the likelihood of a heating-less variant is clearly higher. That doesn't replace the number, but it saves time when sorting large photo series.
Collect freight classes systematically
Every documented sighting grows your picture of which machines are in service where.
Placing it within railway operations
A freight diesel locomotive moves in different spaces from a passenger locomotive. That determines where you’ll get to see it at all.
| Location | Chance of a sighting | Why |
|---|---|---|
| Marshalling and freight yards | high | Transfers, train formation, standing times – easy to view from the public edge |
| Private sidings and industrial areas | medium | Serving runs are irregular, often in the morning |
| Engineering sites with works trains | medium | Private keepers use the class in front of engineering trains |
| Passenger stations without freight traffic | low | Without train heating, no scheduled passenger workings |
| Purely electric lines with no diesel traffic | very low | Diesel duties there are worked electrically instead |
Marshalling yards are the richest observation ground for this type of vehicle – how to spot there sensibly and within the rules is described in the guide to spotting at marshalling yards.
Only from public locations
Track installations, shunting areas, depots and stabling sidings are operational or private land and must not be entered. Observation and photography happen only from platforms, public paths, bridges and streets. In shunting areas, vehicles often move without warning and quietly – that's not a theoretical risk.
What changes and what doesn’t
For the 225, one caveat belongs firmly in the description: keeper, livery and operating area are in motion. Withdrawn locomotives move to construction firms, private freight operators and locomotive lessors. That means markings, colour schemes and operating areas often change on a yearly rhythm.
A close look pays off in detail too. Frame and buffer-beam shape, the layout of grab rails, retrofitted train-protection and radio aerials on the roof, and extra shunting steps often distinguish individual vehicles more clearly than class membership would suggest. Such retrofits happen vehicle by vehicle and spread over years – two locomotives of the same class don’t have to look alike, then. For identification that means: differing details are no argument against a class assignment, but normal.
What stays constant, by contrast, are the basic technical features: wheel arrangement, body shape, drive type, and the fact that no train heating is fitted. Base your identification on these features, then, not on the colour. And log every sighting with a date – only that way does it later become clear what condition and which keeper you found the machine with. The guide to the sighting logbook shows how to do that in a structured way.
For distinguishing within the family, the direct comparison with the widespread Class 218 and with the base type, the Class 216, helps.
Common mix-ups
It points to the 225, when …
- the vehicle number begins with 225
- the locomotive belongs to the V 160 family and stands in front of a freight or engineering train
- no connections or displays for train heating are visible
Look more closely, when …
- you can't read the number – then the 215 and 218 are equally possible
- the machine is running in a private-operator livery with no visible class marking
- it's running solo and the train formation gives no clue for identification
It's not a 225, when …
- you count six axles
- the locomotive has a centre cab with a long and a short bonnet
- the number begins with 218, 232, 261 or 265
Conclusion
The Class 225 is less a vehicle of its own than an operational decision that got its own number. Anyone who understands that reads German class numbers differently: not as a type plate, but as a statement about permitted use. In the field, the simple rule still holds – determine the family by axle count and body shape, the class by the number, the keeper by the markings.
Bottom line
A four-axle V 160-type vehicle without train heating, intended for freight trains: that's the 225. Not distinguishable from the 215 and 218 by looks alone – the number decides. Keeper and operating area keep changing, so check the current picture.
Summary
- The Class 225 is a textbook example of how the German class system reflects changes to equipment through a new number.
- Technically it's a 215 without train heating – intended for heavy freight traffic on lines without overhead wires.
- Identification in the field goes via the family first, then the number; the train formation only gives a clue.
- The current stock lies mostly with private keepers and keeps changing.
Frequently asked questions
What is the Class 225?
A four-axle diesel-hydraulic main-line locomotive for freight traffic. It was created from Class 215 locomotives whose train heating was removed because they were only used in front of freight trains any more. Wheel arrangement, body shape and top speed stayed unchanged – what changed was the use, and with it the class number.
How do I tell the 225 and the 218 apart?
Hardly, on the outside. Both belong to the V 160 family with the B'B' wheel arrangement and a closed body. The difference lies in the train heating: the 218 has a heating generator for passenger trains, the 225 has none. In the field, the vehicle number decides, together with the clue of what's coupled behind the locomotive.
Why does a locomotive get a new class number when only the heating changes?
Because the German class system reflects not just the design, but also what the vehicle may be used for. A vehicle without train heating can't haul passenger trains, so it's assigned its own class. That way, the number alone tells you what a locomotive is allowed to do.
Where can you see the Class 225 today?
Mostly with private freight operators, railway construction firms and on engineering-train duties. It no longer plays a role at DB Cargo. Which keeper is currently running which locomotive changes with contracts and sales – check the current picture through sighting reports rather than older overviews.
What does diesel-hydraulic mean?
Engine power is transmitted to the axles through a hydraulic torque converter, rather than through a generator and electric traction motors. That was the Bundesbahn's standard approach for main-line diesel locomotives. Six-axle types from former Reichsbahn stock work diesel-electrically instead.
How do I tell exactly which 225 is standing in front of me?
By the full vehicle number on the front and side wall. For currently registered locomotives, the twelve-digit UIC number with country and keeper code is added. Especially with private keepers, the keeper markings are the quickest way to the current owner, because liveries change.
Does the 225 have a different top speed from the 215?
No, the 140 km/h rating was kept. In freight service that's rarely reached anyway, because wagon consists and line clearances set lower values. In practice, the reserve still matters: it allows transfer and replacement workings without a path conflict.
Does the Class 225 also haul passenger trains?
Not as a matter of course, because it has no train heating. On special trains with unheated or self-supplied coaches, use is conceivable, but it stays the exception. For passenger workings, classes with electric train heating are used in practice.
