DB Class 110 (E10)

Updated: August 2026 – If a boxy, blue or red electric locomotive with four axles stands in front of a rake of coaches from another era, chances are high that an E 10 is hauling it – officially the Class 110. It was Bundesbahn’s standard passenger locomotive for decades. This page shows you how to recognise it, how it relates to its sister designs, and where you can encounter it today.

What is the Class 110 (E10)?

The Class 110 is a four-axle electric locomotive for passenger services, built between 1956 and 1969 for Deutsche Bundesbahn. It was rated for 150 km/h; the faster 110.3 sub-variant reaches 160 km/h. Until the 1968 renumbering it carried the designation E 10, which remains more common in the enthusiast community today than the plain number.

Its significance stems from the procurement concept behind it: it’s part of the standard-locomotive family, with which Bundesbahn put post-war electric operations on a shared technical footing. For spotters, that’s the key piece of information – because this family looks similar and is therefore regularly confused.

The standard-locomotive family at a glance

Old designation	Current class	Role	Wheel arrangement
E 10	110	Passenger service, faster trains	Bo’Bo’
E 40	140	Freight service	Bo’Bo’
E 41	141	Light general-purpose locomotive for local services	Bo’Bo’
E 50	150	Heavy freight service	Co’Co’

Four designs, one technical basis, different configurations. For identification, that gives a clear order of steps: six axles rule out the 110 immediately – then you’re looking at the family’s heavy freight design. If four axles remain, only the class number helps, because the four-axle members look very alike: 110 stands for the passenger machine, the Class 140 (E40) for the freight variant with a different configuration.

Two classes of their own later emerged from the 110: the Class 113 (E10) and the Class 115 (E10). Both carry their origin in their name – a good example of how the German class number is not just a label but an assignment. The guide to identifying classes explains how to use this system systematically.

Recognition in four steps

Where it fits in: regular service is history

Important for planning: there are no scheduled Class 110 passenger services left. Anyone wanting to see one works with dates, not timetables.

Opportunity	Realistic chance	How you’ll find out
Special trains run by societies and organisers	good on specific dates	Event calendars, society websites, specialist forums
Heritage railways and railway museums	good, partly on static display	Opening hours and announcements
Transfer and workshop runs	down to luck	Short-notice community reports
Engineering-train and special duties by private operators	rare, variable	Check current sightings
Regular passenger timetable	none	The class has been withdrawn

The guide to heritage railways and special trains describes how to find such dates in the first place.

Why the standard-locomotive concept was so successful

It’s worth taking a brief look at the idea behind the family – it explains why these vehicles shaped the German rail scene for decades.

After the war, Bundesbahn faced the task of re-equipping a largely destroyed and only partially electrified network. Instead of developing a separate design for every task, it opted for a shared technical toolkit: the same motors, the same transformers, the same control technology, plus a largely identical locomotive body. The main differences were gear ratio, braking equipment and axle count.

The advantage lay in maintenance: a workshop able to repair the passenger locomotive could also repair the freight locomotive. Spare parts fitted across the family, and staff only had to master one technology.

For you as an observer, that has an immediate consequence: the family is visually hard to tell apart. That’s exactly why the vehicle number is so central for these locomotives – it’s often the only difference you can reliably read from the outside.

Photo tips for the 110

Vintage locomotives reward a different approach than modern vehicles – their appeal lies in detail and material.

• Look for side light. The angular surfaces and rivet rows of older locomotives only stand out in flat light. Midday sun makes them look flat.
• Emphasise the bügelfalte. On the 110.3 sub-variant, the front edge is the design’s signature feature – a slight three-quarter angle shows it best.
• Photograph the markings too. Society locomotives with historic markings often carry the old E 10 number. It belongs with the sighting.
• Use the train as context. With special trains, the coaching stock tells half the story. A shot including the rear of the train is often more expressive than a pure locomotive portrait.

The basic technique – choosing a spot, shutter speed, composition – is covered in the guide to taking good photos of trains. And without exception: tracks, operational railway land and depots are off limits. They are private property, entry is prohibited and dangerous – even on heritage railway premises, the operators are in charge.

Common mix-ups

Verdict

The Class 110 is the starting point for an entire chapter of German electric locomotive history: classes of their own emerged from it, its sister designs covered freight and local services, and its number still explains how the German system works today. You can recognise it by four axles, a boxy shape and – on the fast sub-variant – the bügelfalte nose. You’ll only encounter it now at special trains and in collections such as the DB Museum Koblenz.
