Class 626 (NE 81)

Updated: August 2026 – Not every vehicle on the German network comes from the state railway. The NE 81, now listed as Class 626, was the standard railcar of the non-federal railways: a deliberately plain diesel railcar that could be combined with driving and non-driving trailers to form longer trains. This page shows you how to recognise it and why its name reveals more about procurement policy than about technology.

What is Class 626?

Class 626 denotes the NE 81, a single-car diesel railcar that emerged at the start of the 1980s as a jointly developed standard vehicle for non-federal railways. NE stands for exactly that target group, and 81 for the development period.

The idea behind it is economic, not technical: individual small railways order too few vehicles to secure good prices. A jointly defined standard type lowers procurement costs, simplifies spares holding, and makes workshop knowledge transferable between operators. The result was a deliberately plain vehicle – boxy, functional, with no styling flourishes. It was procured by, among others, the SWEG Südwestdeutsche Landesverkehrs-AG.

In the vehicle classification system the NE 81 sits with the diesel railcars: UIC type code 95, the first two digits of the twelve-digit vehicle number. Whether a vehicle belongs to a state or private railway makes no difference to that.

The modular principle: VT, VS and VB

The real trick of the NE 81 lies not in the railcar itself, but in how it can be combined. Matching vehicles without their own drive belong alongside the railcar.

Car type	Engine	Driving cab	Purpose
Railcar (VT)	yes	yes	runs alone, the system’s base vehicle
Driving trailer (VS)	no	yes	allows turnaround without running the engine round
Non-driving trailer (VB)	no	no	extra capacity at high demand
VT + VS combination	yes	at both ends	typical push-pull formation of small railways

For spotters that has a practical consequence: a train can consist of several vehicles with different numbers. Anyone who only notes down the railcar’s data panel documents the train incompletely. You’ll find the same logic with railbuses such as Class 798, which were likewise assembled on the modular principle.

How to identify the NE 81 in the field

The general sequence for identification – type of traction, build, number – is explained in the guide to identifying rolling stock classes.

Spotting on private railway lines

Private railways work differently from the main network: smaller stations, longer standing times, a sparser timetable – but also less publicly available vehicle information.

What operationally distinguishes local from long-distance vehicles, and why regional vehicles follow quite different logic, is covered by the article local versus long-distance services compared. Because private railway vehicles change owner – and with it number and livery – more often than state railway vehicles, a fixed documentation scheme is worth setting up; see the guide on keeping a sightings log for how that can look.

Non-federal railways: what the term means

The class name contains a term that’s rarely encountered outside the railway world – and understanding it is worthwhile, because it explains a whole part of the German railway landscape.

Non-federal railways (nichtbundeseigene Eisenbahnen) was the term for railways that didn’t belong to the Deutsche Bundesbahn: state and district railways, industrial railways, regional private railways. Buyers of the NE 81 included the Hohenzollerische Landesbahn (HzL). Many of them operated individual lines or small networks, often branching off the main network and frequently with a very modest vehicle fleet.

That small scale is the root problem that led to the NE 81. Anyone needing three or four railcars doesn’t get bulk prices. Anyone running its own bespoke vehicle type has to hold its own spares and workshop know-how. Both are expensive for a small operator. A jointly defined standard type solves exactly these two problems at once – hence the name.

For observers this history is practically relevant, because it explains why private railway vehicles often look and behave differently from state railway vehicles. They frequently carry operator-specific numbers rather than a nationally uniform scheme, they change owner more often over the years, and their liveries follow no central design line. For documentation that means: always note down what’s actually written on the vehicle, and add the class assignment separately from that.

A second point concerns the information available. There’s less publicly available data on vehicles of small railways than on the state railway’s large-scale production runs. Fleet lists are often out of date, information contradicts itself, and changes are rarely reported centrally. That’s exactly why your own, dated observations are so valuable here – they close gaps that no list closes.

And because small fleets can shrink quickly, this applies to these vehicles more than to most others: if you have the chance, take it rather than waiting for better light. Withdrawn vehicles have found a home in some cases with heritage railways such as the Friesoythe-Cloppenburg Heritage Railway.

Common mix-ups and how to rule them out

The modern successor to this role is the single-car Regio-Shuttle RS1 of Class 650 – the same idea of a compact single vehicle, just in a current form. Similarly positioned is the light diesel railcar of Class 672.9, which played a comparable role on East German branch lines.

Conclusion

Class 626 tells a story you can see in the vehicle: a standard type born of economic necessity is bound to look plain. For spotters that’s actually an advantage – the boxy shape is unmistakable, and the modular principle turns every train formation into its own small documentation task.
