Siemens Vectron

Updated: August 2026 – Anyone standing at a German freight line today will sooner or later spot a Siemens Vectron. The platform shapes European freight services like hardly any other class family – and poses spotters a problem of its own: all the variants look almost identical. This page shows you how to tell the differences apart anyway.

What is the Siemens Vectron?

The Vectron is a modular locomotive platform that Siemens has built since 2010. All versions are four-axle, full-width locomotives in the Bo’Bo’ wheel arrangement with two end cabs. What comes out of it is decided by the order: an AC locomotive, a DC locomotive, a multi-system locomotive for cross-border services (MS), or a diesel-electric machine (DE).

This makes the Vectron the successor to the EuroSprinter generation, which includes the ES64F, also known as Class 152. The difference lies less in the base technology than in the thinking behind it: instead of separate classes for separate railways, a platform emerges from which country approvals and electrification systems can be assembled. That’s exactly why the Vectron carries not one but several class numbers in Germany.

Telling the variants apart

The silhouette won’t help you determine the variant – it’s the same across all of them. So you need to look at the roof and the number instead.

Beyond these three basic forms there are hybrid solutions such as the Vectron Dual Mode, which can run on electric or diesel power. Anyone wanting to understand the system behind such identifications in general will find it in the guide to identifying classes.

What the number tells you about the locomotive

The German class scheme has been three digits since 1968. Before that, electric locomotives carried E-numbers – the E 10 became the 110, the E 40 became the 140. Since then the leading 1 has marked electric locomotives, the 2 diesel locomotives. This same logic also applies to the Vectron family and explains an observation that seems confusing at first glance.

Version	German class	Identifying feature on the vehicle
Vectron MS (multi-system)	193	several pantographs, often used cross-border
Smartron (single-system, standard package)	192	two pantographs, German AC network
Vectron DE (diesel-electric)	247	no pantographs, roof housings for cooling and exhaust
Vectron Dual Mode	248	pantographs and diesel housings at the same time

So the diesel variants carry a number in the two-hundreds, even though they’re outwardly sibling models of the electric locomotives. That’s not a contradiction but consistent logic: the first digit describes the mode of traction, not the body shape. The full twelve-digit vehicle number on the side wall adds country and keeper identification – how it’s structured is explained in the article on the UIC number and its check digit.

Spotting: why the Vectron is the most rewarding modern locomotive

Hardly any other current class family offers so much variety. A large share of the fleet belongs to leasing companies such as Angel Trains and changes hirer over the years – and often changes markings with the hirer too. Hirers include Europe-wide freight operators such as Captrain. On top of that come advertising and special liveries that sometimes last only a few months.

For practical purposes that means two things:

• A Vectron isn’t just a Vectron. Anyone who only notes “saw a 193” loses the actually interesting information.
• Timing beats location. A particular livery only exists in a certain window of time. Miss it, and you won’t get it in that form again.

How to search specifically for special designs is covered in the article on advertising locomotives and special liveries. And because the most interesting Vectron sightings often happen in cross-border services, it’s worth taking a look at the overview of border stations for spotting in Germany.

A second reason for this platform’s productivity lies in its deployment pattern. Multi-system locomotives are procured precisely so they can cross borders without a locomotive change – at a system-change station like Bad Bentheim they therefore run straight through, where every train used to swap locomotives. This means a particular machine can be in Germany one day and several countries away just a few days later. Anyone who documents sightings with date and location will actually see such movement patterns in their own data after a while – something that’s barely possible with fixed-roster classes.

In practice that means: note the train type alongside the number and, if identifiable, the direction. A container train heading towards the border – say, at the transfer station Aachen West, where traffic towards Belgium is bundled – tells you more about a locomotive’s diagram than a plain still shot at the platform. And because keeper markings change on leased vehicles, it’s also worth checking the small panel with the full vehicle number – it’s the only detail that stays stable over the years.

Common mix-ups

The most important alternative in German freight services is the TRAXX family from Bombardier. Both families occupy the same niche but differ clearly in their front design – once you’ve seen them side by side, you’ll tell them apart reliably afterwards.

Verdict

The Vectron shows how class identification has changed. In the past, the shape led you to the vehicle; today it only leads you to the platform. Only the roof fittings and vehicle number tell you which variant is in front of you. Anyone who consistently takes this second step has much better data on the current locomotive generation – and quickly recognises how much movement there is in keepers and liveries.
