ÖBB Class 1044

Updated: August 2026 – If one locomotive class embodies an entire railway era for the ÖBB, it’s the Class 1044. Four-axle, 160 km/h fast, with 1970s thyristor technology, and deployed ahead of pretty much whatever the network required. This page shows you how to recognise it, how it relates to the Class 1144, and how to photograph it well.

What is the ÖBB Class 1044?

The Class 1044 is a four-axle general-purpose electric locomotive of the Austrian Federal Railways. It has the wheel arrangement Bo’Bo’, works under 15 kV at 16.7 Hz and is designed for 160 km/h. It’s driven via thyristor control – the technology that marked the transition from classic contactor-controlled locomotives to modern power electronics in the 1970s.

Operationally it was the workhorse of the Austrian Federal Railways: heavy passenger trains over the mountain routes, freight trains, express service. It sits precisely between two worlds – the six-axle vintage classes of the post-war era and the modern Taurus family, which later took over main-line service.

From the 1044 to the 1144: what a conversion means

Some of the machines were later retrofitted and have since carried the class designation 1144. That’s not a detail for statisticians but a pattern you’ll constantly encounter with European railways.

You’ll find the details on the converted variant on the page about the Class 1144. How to quickly find and correctly match vehicle and train numbers in service is explained in the guide to finding the train number.

Field recognition features

Identification always follows the same sequence, and it works even from a greater distance.

The ÖBB’s four-digit class number is more than a catalogue number here. Its first digit encodes the vehicle type: 1xxx electric locomotive, 2xxx diesel locomotive, 4xxx electric railcar or multiple unit, 5xxx diesel railcar. This rule applies consistently and is thus the most useful piece of knowledge for anyone identifying vehicles in Austria. The guide to identifying rolling-stock classes additionally describes the general order in which to work through features.

Placement in railway operations

The following comparison shows where the 1044 stands technically and operationally.

Criterion	Vintage class (1950s)	Class 1044 (1970s)	Taurus generation (from 1999)
Axles	six	four	four
Drive technology	classic contactor control	thyristor control	three-phase drive
Maximum speed	designed lower	160 km/h	up to 230 km/h
Design language	boxy, riveted	boxy, angular, smoother	wedge-shaped, aerodynamic
Role in the network	building up electrification	standard general-purpose locomotive	modern general-purpose use

It’s worth comparing with the Class 1042, which represents the generation before it and had a very similar general-purpose role in the network.

Why thyristor technology was a turning point

To understand why the Class 1044 formed the backbone of Austrian main-line service for so long, it helps to look at its drive technology. Older electrics controlled tractive effort through contactors: traction current was switched in in fixed steps, each step a noticeable jump. That worked, but it was crude, prone to wear, and susceptible to wheelslip when starting heavy trains on wet rails.

Thyristor control replaced these mechanical steps with power electronics. Tractive effort could then be dosed much more finely and steplessly. For a network with long gradients, that’s a real advantage: a locomotive that can precisely match its tractive effort to adhesion hauls more trailing load over a gradient than an equally powerful machine with coarse control.

At the same time, this technology marks an intermediate stage. The next generation moved to three-phase drives with asynchronous motors, as later used in the Taurus family – even more finely controllable, less maintenance-intensive, and the basis for speeds of 200 km/h and more.

For you as an observer, that means: if you see a four-axle Austrian electric with a boxy, functional-looking body running ahead of mixed trains, you’ve almost always landed on this intermediate generation. Only the marking reveals the exact class – but you can recognise the era from the shape.

Spotting and photography

Boxy 1970s locomotives have a photographic advantage over modern wedge shapes: their edges catch the light. That’s exactly what you should work towards.

• Look for low-angle light. In the morning and late afternoon, shadows trace the contours of the locomotive body. Midday light makes the surface look flat.
• Prefer a three-quarter view. Around 30 to 45 degrees to the vehicle axis shows the front and the side wall with the marking at once – important, because only the marking tells 1044 apart from 1144.
• Choose your focal length deliberately. For clean side-on shots from a safe distance, a telephoto lens makes sense. What really matters here is covered in the guide to the best telephoto lens for railway photography.
• Choose your location responsibly. Publicly accessible areas only. Tracks, operational railway land and stabling sidings are closed and life-threatening – without exception.

Common mix-ups

Conclusion

The Class 1044 is the key to understanding modern ÖBB fleet history: it stands at the transition from post-war electrification to power electronics, was the standard tool of main-line service for decades, and lives on in the converted Class 1144. Three looks are enough to identify it – axles, shape, marking.
