Class 293 (V 100 East)

Updated: August 2026 – A stocky four-axle diesel locomotive in an unfamiliar company livery, its cab visibly shifted off-centre, a short engineering train in front of it: there’s a good chance you’re looking at a Class 293. This page explains where these machines come from, what the class number really tells you, and how to identify them properly in the field.

What is Class 293?

Class 293 is a four-axle diesel-hydraulic locomotive derived from a Deutsche Reichsbahn V 100. The vehicles were originally built at the Hennigsdorf locomotive works, later withdrawn or sold, and then re-engined – given a new diesel engine and usually overhauled auxiliary equipment too.

Important for understanding this: 293 is a registration number, not a description of the design. It assigns the vehicle to a class group in the national vehicle register. How an individual machine is technically equipped – which engine, which control system, which additional fittings – isn’t stated in the number but in the vehicle’s documents. Two locomotives with a 293 number can differ considerably in detail.

Where these machines come from

The Reichsbahn’s V 100 was a general-purpose machine: light enough for branch lines, strong enough for transfer and shunting tasks, robust enough for continuous duty. It’s exactly these qualities that meant the vehicles weren’t scrapped after their state-railway careers ended, but sold on – to private operators as well as to heritage organisations such as the Eisenbahnfreunde Traditionsbetriebswerk Staßfurt.

This stock gave rise to several conversion families side by side. In the vehicle register you’ll find them under various class numbers – for instance as Class 203, Class 204, or Class 298. Which number a particular machine carries depends on its conversion status and the time of registration, not on a fixed technical feature.

Identifying it in the field: three looks are enough

How the twelve-digit vehicle number is structured and what each block means is explained in the article on the UIC number and its check digit. If you want a systematic approach beyond just this class, the guide to identifying classes helps.

What re-engining means in practice

The term sounds technical, but it has very visible consequences. Re-engining replaces the original diesel engine with a modern unit. Because new engines need different dimensions, different cooling capacity and different exhaust routing, it rarely stops at swapping the engine alone: the cooling system, fans, exhaust and often the cladding of the long bonnet are adapted too.

The reasons are economic. A base vehicle with a robust frame and proven bogies lasts for decades, while engines fall short on fuel consumption, spare-parts availability and emissions rules. Anyone who keeps the base vehicle and renews the powertrain gets a locomotive that meets current requirements for a fraction of the price of a new build.

For you as a spotter, that means: the underframe tells you the origin, the superstructure tells you the conversion. The frame, bogies and cab shape reveal the V 100 ancestry. The cooling grille, vents and exhaust arrangement reveal that the machine has had a second life. Together, the two give you the classification – and also explain why two locomotives with the same class number can look different.

Where the 293 fits into railway operations

The class fills a niche that exists everywhere on the network yet rarely catches the eye: robust four-axle locomotives of medium power for tasks where a large main-line locomotive is too expensive and a light locomotive too weak – operators such as the Preßnitztalbahn use them on engineering, freight and special trains.

Field of use	Likelihood	Why
Transfer runs between freight yard and siding	high	Classic task for robust four-axle locomotives
Engineering trains and construction-site logistics	high	Construction companies lease such machines project by project
Industrial and port railways	medium	Access usually restricted, observe only from outside
Shunting duty at freight yards	medium	Depends on the local keeper
Regular passenger services	very low	These machines are practically no longer used for this today

Spotting and photography

These locomotives rarely stand at the platform. Anyone specifically looking for them has to change their observation strategy: away from watching trains pass through, towards places where shunting happens.

The guide to spotting at marshalling yards shows how to observe shunting facilities sensibly and from publicly accessible points. Industrial, port and private sidings, and regional networks such as Regio Infra Service Sachsen, are private land: entering them is permitted only with the operator’s explicit permission, and tracks and operational facilities are always off limits. Which rules apply around tracks, and why the safety distance is a limit rather than a guideline, is covered in the article on safety distance from the track.

Common mix-ups

Conclusion

Class 293 is a good example of how, in the modern vehicle register, a class number is more of a pigeonhole than a technical data sheet. The basic shape reveals the origin, the fittings reveal the conversion, and only the complete vehicle number reveals the specific machine. Anyone who keeps these three levels apart quickly arrives at a reliable result for almost all private-operator diesel locomotives.
