Class 462 (Siemens Desiro HC)

Updated: August 2026 – Class 462 belongs to the Desiro HC family from Siemens Mobility and stands out with a silhouette you don’t need to explain twice: flat front end, tall middle section. Trickier is placing the number itself, because the 46x range is tightly packed within the German class scheme. This page shows you how to keep both apart cleanly.

What is Class 462?

Class 462 designates end cars of an electric regional multiple unit from the Siemens Desiro HC family. The layout is distinctive: the two cars with a driving cab are single-deck and carry the traction equipment, while the intermediate cars between them are double-deck and supply the seating. There’s no separate locomotive.

It runs under the German overhead line at 15 kV and 16.7 Hz. The pantograph sits on the roof – an important detail, because it separates the vehicle from every system with a side-mounted conductor rail.

Important for understanding the number: 462 applies to the end cars, not the entire unit. The double-deck intermediate cars run under their own class number, because they’re technically a different car type. You’ll find the same principle across practically every multiple unit.

The 46x block: tightly packed, easy to confuse

Class numbers are allocated sequentially and aren’t sorted by manufacturer. That’s why vehicles with nothing in common sit close together in the 46x range. This overview sorts out the levels that get muddled during identification.

Level	Example	What it tells you	Changeable?
UIC type code	94	electric multiple unit, uniform across Europe	no
Class of the end cars	462	car type with a driving cab	rarely
Class of the intermediate cars	own number	car type without a driving cab in the same unit	rarely
Four-digit variant	2462, 3462, 4462	same family, different numbering block	rarely
Operator and network	changing	who’s currently providing the service	yes, with every award

Direct neighbours in the same number range belong to entirely different vehicle families – for example Class 463 / 464 (Siemens Mireo), a single-deck regional multiple unit with no double-deck element at all. Conversely, Class 2462 and Class 4462 designate the same manufacturer family as the 462, just in a different numbering block.

Identification in four steps

The basic sequence – vehicle category, design, class – is explained in the guide to identifying classes. How the twelve-digit number is structured and what the check digit means is covered in the piece on the UIC number.

Place in railway operations

Multiple units with mixed car height are capacity vehicles for high-demand Regionalexpress services. They close the gap between single-deck regional multiple units, which let passengers board and alight faster, and pure double-deck trains, which offer more seats but need more time at the platform.

For observation this means: you’ll find them on the main axes in and around conurbations, not on lightly used branch lines. Exactly which relations that means, though, is not a fixed property of the class. Service contracts are re-tendered, vehicles migrate between networks, engineering works lead to substitution concepts. Anyone searching deliberately therefore checks the current status via real-time information and current sightings rather than older overviews.

Another point matters more for choosing your spot than it sounds: these vehicles are long. A unit no longer fits fully into the frame at many platforms, and certainly not when running in multiple. Anyone wanting to show the characteristic step up in height needs not the nearest platform but one with a clear end and enough distance from the track centre line. A place where the trains also stop as scheduled is nearly always better than a pure passing point – standing still, you can compare car heights, read numbers and calmly decide which variant you’re actually looking at.

Photography and safety

The Desiro HC is a subject where the camera angle makes half the picture.

• From an angle. Only this way do the flat front end and the tall middle section come together in the frame – head-on the train looks like an ordinary single-deck multiple unit.
• Longer focal length, more distance. This reduces converging lines on the tall car sides.
• A second shot of the side wall. A tight crop with a fully legible class number makes the sighting verifiable.
• Early or late light. Flat light draws out edges and the step in height far better than midday sun.

The technical basics for this – depth of field, shutter speed, panning – are covered in the guide to taking good photos of trains.

On the platform, without exception: stay behind the safety line, don’t enter the track area and don’t flash towards the driving cab. Tracks, operational installations and storage sidings are operational railway land; entering trains generate a slipstream that’s especially strong against tall car sides. The binding rules are always the local ones and the instructions of staff.

Common mix-ups

The practically most common misidentification doesn’t happen between designs but between numbers: 462 and 4462 are barely distinguishable in a blurry photo. A clean second shot of the side wall solves this problem permanently.

Conclusion

Class 462 is visually easy and number-wise hard. You recognise the design from a single feature – the step up in height between the flat front end and the double-deck middle section. Getting the exact match within the family right, though, only works with a fully read class number, because the same vehicles run under three- and four-digit numbers. Keeping both apart gives you a sighting you can rely on.
