Stern & Hafferl Verkehrsgesellschaft m.b.H.

Updated: August 2026 – Anyone looking into Austrian local railways quickly comes across a company name made of two personal names: Stern & Hafferl Verkehrsgesellschaft m.b.H. The company stands for a form of operation that still goes its own way technically today. This page explains why local railways can have differing overhead line voltages, what that means for their vehicles – and how to recognise such lines in the field.

What is Stern & Hafferl Verkehrsgesellschaft m.b.H.?

Stern & Hafferl Verkehrsgesellschaft m.b.H. is an Austrian transport company that stands for operating local railways. The company name follows a classic pattern: two personal names, joined by the ampersand, plus the suffix Verkehrsgesellschaft and the Austrian spelling m.b.H. for the company with limited liability. The corporate group Stern & Hafferl Verkehrsgesellschaft is profiled separately in the company overview.

Such double names are a hint at a long-established, personally shaped firm – as opposed to invented names or abbreviations, as newer companies tend to carry. You’ll find comparable regional operators in this database too, for example the Lambach–Vorchdorf-Eggenberg Local Railway, the Linz AG Lines or the Vienna Local Railways. All three show how differently the term local railway is filled out in Austria – from a pure valley line to a near-urban interurban service. With its own livery, the Salzburg Local Railway operates in the same segment.

Why local railways go their own way on overhead line

On main lines the power supply is largely standardised today. Local railways look different: many of these lines were electrified early and regionally independently, often in connection with a local power plant. Back then there was no system that would have imposed itself; operators chose what suited the line length, the available power and the vehicles on offer.

These early decisions still have an effect today, because a system change never affects only the overhead line.

Affected part	What a system change means
Overhead line	new design of cross-section, insulation and clearances
Substations	different conversion and different feed-in
Traction vehicles	conversion or complete new procurement
Workshops	new test equipment, new spare parts, new training
Operations	transition points and operating pauses during the conversion

Because all five points arise at once, established systems often persist for decades. For vehicles this means: they’re tied to their system. A multiple unit built for a particular voltage can’t simply be deployed elsewhere – unless it’s expressly built to be multi-system-capable.

Multi-system capability: the exception, not the rule

Vehicles that can handle several power systems exist above all in international traffic. They carry the necessary technology with them: different pantograph heads, additional protection and switching equipment, and correspondingly more elaborate control systems.

A well-known example from Austrian main-line service is Class 1216 (Taurus III), which is designed for use under several systems. For local railways, this effort usually isn’t worthwhile, because the vehicles never leave their own network. That’s why simpler but precisely matched vehicles are common there. How different electric traction vehicles can be is shown by comparing the main-line locomotive Class 1063 with the electric multiple unit Class 4020.

How to systematically classify unknown vehicles is described in the guide to identifying classes.

Recognising and documenting local railways in the field

Local railway lines look different from main lines – and that can already be observed from a public path.

Tips on a safe location are given in the guide on safe distance from the track; how the long vehicle number is structured is explained by the guide on the UIC number.

Why small systems are so long-lived

A second reason local railways stay technically self-contained lies in the size of their vehicle fleets. Anyone who only needs a few traction vehicles doesn’t buy a large series. They buy one-offs, small series or second-hand vehicles – and then keep them in service for a very long time.

That creates a cycle that stabilises itself: the workshop knows exactly these vehicles, keeps matching spare parts, and builds up years of experience with their technology. A system change would devalue all of that. For observers this is a stroke of luck, because vehicle generations last noticeably longer there than in the wider network.

Feature	Large networks	Local railways
Procurement	large series, Europe-wide tender	small series, one-off or second-hand vehicle
Service life	planned replacement after generations	often noticeably longer operating periods
Spare parts	series supply from the manufacturer	in-house manufacture and stockpiling
Technical diversity	standardised	historically grown, sometimes inconsistent
Photographic significance	standard vehicles, comparable everywhere	rare types, barely documented

That’s exactly why sightings at local railways are unusually valuable: what runs there is often seen nowhere else – and when such a vehicle is retired, it disappears for good. How far such vehicle worlds reach back is shown by the museum-operated Bregenzerwaldbahn (Wälderbähnle).

Common mix-ups

• Light overhead line read as harmless – every overhead line carries lethal voltage, regardless of the system.
• Local railway equated with tramway – both can look similar but follow different sets of rules.
• Running number assumed to be unambiguous – without the company stated, it can’t be matched up.
• Vehicle swapping between lines assumed – with differing power systems, that’s simply not technically possible.
• Little traffic read as low risk – on quiet lines especially, trains arrive unexpectedly.

Verdict

Local railways aren’t scaled-down main lines but independently grown systems. The overhead line voltage is the most striking example of that: it was decided regionally, it ties down the vehicles – and it explains why such railways have their own, often long-lived vehicle fleets.
