Key takeaways

  • The 101 is DB's long-distance electric locomotive: 145 engines, built 1996–1999 by Adtranz, designed for 220 km/h.
  • Fastest way to recognise it: four axles, angular front with a raked windscreen, number starting with 101.
  • Its typical use is loco-hauled IC/EC – where multiple units run, the 101 is rare.
  • Advertising locomotives are routine: a large share of the class carries or has carried special liveries.
  • Risk of confusion is greatest with the Class 120, which is technically related but older and differently proportioned.

Identifying features

Is this really the class in front of you?

Tick off everything that applies to the vehicle you are looking at.

  • Angular, slightly forward-raked windscreen with a continuous dark window band
  • Four axles in two bogies – not a six-axle design
  • Single-arm pantograph and a flat, tidy roof without large fittings
  • Vehicle number starts with 101, three-digit running number up to 145
  • Usually at the rear or leading an IC/EC coach rake, not in front of freight trains
  • Often carries an advertising or special livery rather than traffic red

Updated: August 2026 – A red electric locomotive, four axles, an Intercity in front of it: nine times out of ten, you’re looking at a Class 101. This page shows you how to identify it beyond doubt, where you’ll realistically find it, and how to photograph it so the shot actually delivers something.

Spotted a 101? Note the number.

With advertising locomotives especially, precise documentation is worthwhile – done in a few seconds in Traintrack.

What is the Class 101?

The Class 101 is a four-axle electric locomotive for fast passenger service, built between 1996 and 1999 by Adtranz. In total 145 engines were built with numbers 101 001 to 101 145. They’re rated for 220 km/h, produce roughly 6,400 kW, and were procured to replace the ageing Class 103 in Deutsche Bahn AG’s premium long-distance service.

Operationally the 101 is therefore clearly placed: it’s the locomotive in front of loco-hauled Intercity and Eurocity trains – and so the direct successor to the Class 103. Wherever long-distance service has switched to multiple units, it disappears from the picture – and that’s exactly what makes it more interesting for spotters than it was twenty years ago.

The three features that are enough for identification

You don’t need detailed knowledge to identify a 101. Three observations are enough, and they work even from some distance.

Count the axles

Four axles, spread across two bogies. Six-axle locomotives such as the Class 151 or 155 are ruled out immediately.

Look at the front

Angular front, slightly forward-raked windscreen, continuous dark window band. The silhouette looks flat and tidy, without bulky roof fittings.

Check the train behind it

A classic coach rake in IC colours is a strong indicator. You'll practically never see the 101 in front of freight trains.

Once you’re confident of a 101, the main remaining confusion is with the technically related but older Class 120. If any doubt remains, the vehicle number settles it: it starts with 101 and ends at 145. How to quickly read and correctly place such numbers in service is explained in the guide to finding train numbers and vehicle numbers; the full international system behind it is in the article on the UIC number and its check digit.

Practical tip for the first glance

Count the axles first, not the details. You can see the axle count even in poor light and from 200 metres away – you can check the front shape and number afterwards, at your leisure.

Which red electric locomotive is that, really?

The most common mix-ups don’t happen with exotic classes, but among the well-known red electric locomotives. The following finder narrows it down using three observations.

Quick identification: red electric locomotive in passenger service

Three questions, one assessment. The vehicle number remains the final word.

Likely

Class 101

Four axles, a flat angular front, long-distance coaches behind it: that's the typical picture of the 101. Check the vehicle number to be sure.

Likely

More likely a regional locomotive

Other classes usually run in front of double-deck coaches in local service. Watch the number – if it starts with 111, 112, 114 or 146, the 101 is ruled out.

Likely

Not a 101

Six axles or a freight train attached clearly speak against the Class 101. Freight classes and older general-purpose locomotives are candidates here.

If you want a systematic approach rather than just this one class, the general guide to identifying locomotive classes helps – it explains the order in which to work through features.

Where you’ll find the Class 101

The locomotive follows loco-hauled long-distance service – no longer only DB’s, either, since individual hired-in engines also run in front of FlixTrain trains. That gives a simple rule: the more classic IC coach rakes run on a route, the higher your hit rate. A hub like Frankfurt (Main) Hauptbahnhof is therefore productive: a locomotive stands in front of every IC coach rake there, and the change of direction at the terminus gives you time for the number.

Location Chance of a sighting Why
Major hub stations with long-distance service High Locomotive changes, turnaround times and long standing times at the platform
Long-distance routes with IC/EC service High This is where the loco-hauled stock runs on schedule
Routes served purely by ICE Low Multiple units dominate there, without a separate locomotive
Regional hubs without long-distance service Very low No scheduled use
Stabling sidings and station approach areas Medium Locomotives wait there between two workings – often clearly visible

Stock and use change

Which diagrams are currently run loco-hauled shifts with every timetable change. Don't rely on lists from the internet, but check the current situation – via real-time information, community sightings and your own observation.

In local service, this role is traditionally taken by the Class 111, which you’ll find at the same stations, but in front of different coach rakes. For choosing a specific location it’s worth looking at the overview of the best stations for trainspotting in Germany. If you’d rather go out spontaneously, combine that with live sightings and real-time data.

Advertising locomotives: why documentation pays off

Hardly any other German class runs as an advertising medium as often as the 101. Over the years a considerable share of the 145 engines has carried special liveries – some for years, others for just a few months.

For spotters that means two things:

  • A 101 isn’t just a 101. Anyone who only notes “saw a 101” loses the actually interesting information.
  • Timing beats location. A particular livery exists only within a certain window of time. Miss it, and you won’t get it back.

That’s why every sighting should include at least the vehicle number, date and livery. How to record this cleanly and in a usable way is shown in the guide to keeping a sighting log; how to specifically search for special liveries is covered in the article on advertising locomotives and special liveries.

Photo tips specifically for the 101

The 101 is a rewarding but unspectacular locomotive: a flat front, little structure, often in unfavourable platform lighting. If you want to show it working rather than standing still, the Geislingen Incline offers a suitable line-side photo spot. These four points make the difference.

Three-quarter view instead of a head-on shot

An angle of roughly 30 to 45 degrees to the vehicle axis shows the front and side wall at once – making the flat front look more three-dimensional.

Sun behind you, but not overhead

Low light in the morning or late afternoon draws out the edges. Midday light makes the smooth front look flat.

Short shutter speed for passing trains

For a sharp still shot of a passing locomotive, 1/1000 s is a usable starting point – adjust it for speed and distance.

Include the livery in the shot

With advertising locomotives, the side wall is the actual information. Plan the framing so it's fully in shot.

Which focal length is sensible for this, and where the limits of cheap telephoto lenses lie, is covered in the guide to the best telephoto lens for railway photography. The fundamental technique – panning, the plane of focus, exposure – is in the guide good photos of trains.

Common mix-ups and how to rule them out

It points to the 101 when …

  • the locomotive has four axles
  • an IC or EC coach rake is attached
  • the front looks flat and angular
  • the number starts with 101

Look more closely when …

  • the locomotive carries a special livery and you can't place the shape
  • it's in front of a substitute or special train
  • you only see it from behind or against the light

It's not a 101 when …

  • you count six axles
  • a freight train is attached behind it
  • the number starts with 111, 112, 146 or 193 – then you're looking at classes such as the 111 in local service

Verdict

The Class 101 is one of those vehicles you learn properly once and then recognise everywhere afterwards. Axle count, front shape and train type lead to the right answer within seconds, and the vehicle number provides the confirmation. What makes it exciting is less its technology than its liveries and the shrinking amount of loco-hauled long-distance service – both good reasons not just to make sightings, but to record them too.

In short

Four axles, flat front, IC coach rake: that's the 101. Anyone specifically looking for it should focus on loco-hauled long-distance service – and note the number and livery, because those are exactly what change.

Summary

  • The Class 101 replaced the Class 103 in premium passenger service from 1996 and still shapes the image of loco-hauled long-distance trains today.
  • Three features are enough for identification: axle count, front shape and the vehicle number.
  • Anyone wanting to photograph the 101 deliberately should look for long-distance routes with loco-hauled trains – that's where the hit rate is highest.
  • Documenting sightings with number and livery is especially worthwhile, because advertising locomotives change regularly.

Frequently asked questions

How do I reliably recognise the Class 101?

By three things: it has four axles in two bogies, an angular front with a slightly raked windscreen and a continuous dark window band. The vehicle number starts with 101. If it's in front of an Intercity or Eurocity, the identification is practically certain.

How many Class 101 locomotives are there?

145 engines were built, numbered 101 001 to 101 145. How many are actually in service at any given time changes constantly due to inspections, accident damage and withdrawals.

How fast does the Class 101 run?

The top speed is 220 km/h. That's only reached on suitably cleared lines; in everyday operation the timetable sets the pace, not the locomotive.

What's the difference between the Class 101 and the Class 120?

Both are four-axle three-phase locomotives for passenger service, but the 120 is significantly older (1980s) and looks differently proportioned with its more rounded front and larger roof fittings. If in doubt, the vehicle number settles it.

Why do you see so many advertising locomotives from the Class 101?

The class runs in highly visible long-distance service and so lends itself as an advertising medium. A considerable share of the 145 engines has carried special liveries over the years – some for only a few months, which makes them especially interesting for spotters.

Does the Class 101 also haul freight trains?

That's the exception. The 101 is a passenger locomotive designed for fast long-distance service. In front of freight trains in Germany you're more likely to find classes such as 185, 189 or modern Vectron engines.

Where are the best chances of seeing a 101?

On long-distance routes with loco-hauled IC and EC trains, especially at major hub stations with longer standing times. On routes served purely by ICE you'll barely encounter it.

How do I tell exactly which 101 is in front of me?

By the full vehicle number on the side and at the cab. It follows the pattern 101 0xx to 101 145 and, together with the UIC number, is the unique identifier – important if you want to document sightings cleanly.
