What is the Class VT 11.5?
The VT 11.5 is a diesel-hydraulic multiple unit of the Deutsche Bundesbahn, put into service in 1957 for the Trans Europ Express. The Bundesbahn was absorbed into Deutsche Bahn AG in 1994, whose museum stock now holds some of the surviving vehicles. It consists of two power cars with unpowered intermediate coaches placed between them – a closed train with a continuous gangway that runs as a single unit.
The reason for the diesel drive lay in Europe’s 1950s infrastructure. Cross-border lines were in some cases not electrified at all, in others electrified with different electrification systems. A diesel multiple unit ran across all these system boundaries without locomotives having to be swapped at the border. That made the VT 11.5 the ideal vehicle for a European train system aiming to cut journey times.
The body style is remarkable: unlike a locomotive-hauled train, the traction equipment is spread over both ends, while the intermediate coaches are pure passenger coaches without drive. The train runs as a closed unit that isn’t split up and reassembled on the platform. This very principle – power cars on the outside, unpowered coaches inside – later shaped the first generation of high-speed trains too, and is still found in many long-distance trains today.
With the 1968 EDP renumbering, the VT 11.5 became Class 601.
Three designations for one vehicle family
Few vehicles show German numbering history so compactly:
- VT 11.5 was the original category designation. The abbreviation VT stood for diesel railcar (Verbrennungstriebwagen) – its counterparts in the system were VS for driving trailer and VB for unpowered trailer. This system described the vehicle’s role, not its manufacturer.
- Class 601 came about with the switch to EDP numbers in 1968. Letters became number blocks, and the 6xx range took in the railcars.
- Class 602 denoted power cars converted to gas-turbine drive – an episode that stayed technically interesting but had no future.
Above all this sits today’s twelve-digit UIC number, whose first two digits give the vehicle type: 95 for diesel railcar. The code separates by category, not by standing – the TEE multiple unit and the branch-line railbus sit side by side in it. How the number is built up in detail is explained in the guide to the UIC number.
How to identify the VT 11.5
Look at the nose shape
Strongly rounded, deeply drawn down, with a raised driving cab. This silhouette is unique among German diesel vehicles.
Check the colour scheme
Red and cream with a wraparound dividing line – the classic TEE livery. It's unmistakable even from a great distance.
Take in the train layout
Power cars at both ends, with unpowered intermediate coaches and a continuous gangway between them. The train runs as a closed unit.
Read the markings
Depending on the state of preservation, you'll find historic markings as VT 11.5 or later Class 601 numbers. Photograph both.
How to build such feature chains in general is described in the guide to identifying locomotive classes.
Its place in railway operation
The VT 11.5 has long belonged to the historic stock. The same rule applies to the search as for any museum vehicle: the events calendar replaces the timetable.
| Search route | Chance of success | What you get there |
|---|---|---|
| Railway museums and heritage sites | high | Exhibition vehicles, reliable opening hours |
| Anniversaries and special events | medium | Rare movements, often announced well in advance |
| Enthusiast forums with special-trip threads | high | Tips on transfer runs and dates |
| Community sightings with date and photo | medium | Current location and actual condition |
| Older location lists online | low | Often outdated – vehicles get moved and restored |
| Scheduled timetable | none | No more scheduled service |
Location and condition are changeable
Surviving vehicles of this scale get restored, moved and put into storage for periods. Check directly with the museum or society before any trip whether the vehicle is even accessible – that saves long and wasted journeys.
Where was it last reported?
Current sightings from other spotters are the most reliable snapshot for rare historic vehicles.
Spotting and photo tips
The VT 11.5’s strength is its shape. A front-on shot flattens the rounded nose and wastes exactly what makes the vehicle special.
Go low and shallow
A low viewpoint and an angle of about 30 to 45 degrees to the vehicle axis let the curve of the nose read as three-dimensional. Flat light in the morning or late afternoon picks out the edges, while midday light makes the large blocks of colour look flat.
Inside museum halls, the light is the real challenge: mixed light sources, strong contrasts between window fronts and dark corners. A tripod is often not allowed there, so a steady hand and high sensitivity are the more realistic solution. The basic technique is covered in the guide to good photos of trains; how to find dates in the heritage-railway world is in the heritage railway guide.
The operator’s house rules apply without exception on museum grounds. Keep to marked paths and barriers and don’t enter track areas – not even to get a better angle. Shunting takes place in exhibition halls, and many vehicles stand on operational track.
Common mix-ups
It points to the VT 11.5 if …
- the nose is strongly rounded and deeply drawn down
- the vehicle is painted in the red-and-cream TEE colour scheme
- power cars run at both ends with intermediate coaches in between
- the markings show VT 11.5 or a 601-series number
Look more closely if …
- only a single power car is visible without a train formation
- the vehicle stands in a different state of preservation
- you're unsure whether it's a 601 or a converted 602
It is not a VT 11.5 if …
- the train carries a pantograph
- the front end is angular and modern in design
- the vehicle number falls into a different class block
The East German counterpart from the same era is the VT 18.16, likewise a premium diesel express multiple unit. The late revival of the concept – long-distance travel with diesel multiple units – is represented by the Class 605 (ICE TD), while the Class 610 stands for fast diesel service on winding main lines.
Verdict
The VT 11.5 is more than a vehicle: it stands for a time when diesel drive was the most elegant solution in European long-distance travel, because there was no continuous electrical network. Its shape is unmistakable, and its numbering path from VT 11.5 via 601 to 602 is a lesson in German designation systems. Today you only get to see it where museums and societies keep it alive – and that’s exactly why it’s worth documenting every encounter properly.
Quick verdict
Rounded nose, red-and-cream TEE colours, power cars at both ends: that's the VT 11.5, later Class 601. It no longer runs to schedule – the search runs through museums, anniversaries and current sighting reports.
Capture rare encounters
Number, place, date and occasion in one app – with historic multiple units, every sighting is a one-off.
Summary

- Its rounded nose and TEE livery make its body style unmistakable.
- The path from VT 11.5 via 601 to 602 shows three chapters of German railway history in a single vehicle family.
- Surviving vehicles are museum stock; services are one-off events and deserve careful documentation.
Frequently asked questions
What is the VT 11.5?
The VT 11.5 is a diesel-hydraulic multiple unit of the Deutsche Bundesbahn, put into service in 1957 for the Trans Europ Express. It consists of two power cars with unpowered intermediate coaches placed between them. With the switch to EDP numbers in 1968 it became Class 601.
What was the Trans Europ Express?
The TEE was a European train system for premium, cross-border travel, first class only. Because many lines at the time weren't continuously electrified, or used different electrification systems, diesel multiple units were used – doing away with a system change at the border.
How do I recognise a VT 11.5?
By the combination of a rounded, deeply drawn-down nose, the raised driving cab and the red-and-cream TEE colour scheme. Add to that the layout: a closed train with power cars at both ends and unpowered intermediate coaches in between.
Why did the VT 11.5 become Class 601?
Because the Deutsche Bundesbahn replaced the old category designations with EDP numbers in 1968. The abbreviation VT for diesel railcar (Verbrennungstriebwagen) disappeared, and vehicles moved into numbered class blocks. The 6xx range took in the multiple units.
What's the story with Class 602?
Some of the power cars were converted to gas-turbine drive and subsequently run as Class 602. The experiment remained an episode in the vehicle's history. For identification, that means a vehicle of this body style may have run under three different designations depending on the period.
Is the VT 11.5 still running?
Not in scheduled service. Surviving vehicles stand in the museum world. Whether and when one of them is moved is up to its owner – only the museum or society's up-to-date information is reliable, not an older list found online.
Where can I see the VT 11.5?
Realistically at exhibitions, anniversaries and special events in the museum world. The way there leads through museums' and heritage railways' event pages, through enthusiast forums and through current sighting reports from other spotters. Fixed location details from older sources should be treated with caution.
What does the type code 95 say about this train?
The first two digits of the twelve-digit UIC vehicle number describe the vehicle type, and 95 stands for diesel railcar. The code separates by category, not by standing or speed: a TEE multiple unit and a branch-line railbus fall into the same type group.
