Last year, Tremonia Mobility's City 75 ELECTRIC was honoured as "Minibus of the Year 2025" and won over the international jury of experts. From 15 December 2025, six e-vehicles of this type will be making their rounds in Traun as "Mein Spetzi". They are the quietest e-buses in their class, have a long range, are easy to drive and feature state-of-the-art safety assistants. A further two diesel-powered buses from the same manufacturer complete the Traun city bus fleet. These were also recognised as the best vehicles in their class in 2019. The new, improved city bus service can be tested free of charge at the start: The new Traun city bus will be on the road from 15 December and can be used free of charge on any number of journeys up to and including 31 January 2026.
With the launch of the new city bus concept on 15 December 2025, the city of Traun is facing a significant change in local public transport. Four routes (631, 632, 633 and 634) will serve the Traun urban area every half hour. New areas such as (Alt-) St. Martin will be integrated into the public transport network, and three of the four lines will run to the Traun junction. A key aspect of the timetable design was to provide attractive transfer options to local trains, regional buses and trams, thus creating access to the region's entire public transport network. "The new city bus concept expands the timetable offer by 45% compared to the previous offer in Traun. 335,000 timetabled kilometres per year mean a massive improvement and optimisation of the existing service, with attractive transfer connections to local trains, regional buses and the tram," says a delighted Günther Steinkellner, Provincial Councillor for Mobility and Infrastructure.
"The new city bus concept will make public transport in Traun much more attractive and create convincing incentives for more and more people to leave their cars at home and switch to environmentally friendly public transport," says Herwig Mahr, Member of Parliament and Deputy Mayor, with conviction.
Traun Mayor Karl-Heinz Koll also wants to position the new city bus as a reliable, trusted helper in everyday life: "We also wanted to express this with the name "My Spetzi". As a friendly friend and daily companion to the people of Traun, the Traun city bus fulfils key mobility needs in a simple, convenient and sustainable way. 'Mein Spetzi' takes everyone in Traun safely, comfortably and stress-free to every important place in the city - even free of charge for the first seven weeks."
The municipality is deliberately breaking new ground with the Traun city bus: "Six of our eight new vehicles are 100% electric. This not only means significant CO2 savings, but also less environmental and noise pollution for the people of Traun. Due to their small and manoeuvrable design, they provide significant traffic relief, especially in the city's narrow residential areas," says Transport Councillor Gernot Metka.
However, it is also important to raise awareness of this environmentally friendly mobility option. "By offering free travel for the first seven weeks until 31 January 2026, we want to give all Traun residents who otherwise rarely or never use public transport the opportunity to hop on and try out the new city bus service in a simple and uncomplicated way. Our aim is to make the 45% expansion of the city bus service visible right from the start and thus get even more people interested in public transport," explains Klaus Wimmer, Managing Director of OÖ Verkehrsverbund Gesellschaft .
On the road with the "minibus of the year 2025"
The new city bus concept implements precisely the changes that the people of Traun had requested in a public survey in advance: smaller and more manoeuvrable vehicles, predominantly electrically powered and therefore much quieter in residential areas. The right partner was found in the German manufacturer Tremonia Mobility. "The City 75 ELECTRIC is designed for routes that are too narrow for larger buses in order to ensure a flexible and efficient service. It has a range of up to 300 kilometres and the powerful electric drive ensures a smooth and efficient speed in urban areas and therefore also low emissions," explains Christian Wünsch, Head of Sales at Tremonia Mobility GmbH. Accessibility is another important issue: the e-bus has a low entrance and is suitable for both wheelchairs and pushchairs. The renowned title of "Minibus of the year 2025" - an award that is given to buses up to 8.5 metres, i.e. also to buses classified as "MIDI" in Austria - was also awarded primarily because it was the quietest minibus in the test. "It is easy to drive, offers comfortable access, flexible seat configurations and state-of-the-art safety assistants," says Christa Trixl, Managing Director of Wilhelm Verkehrsbetriebe GmbH, confirming the advantages of the vehicle type in day-to-day operations.
New old bus operator: Wilhelm Welser Verkehrsbetriebe GmbH
Six of the eight new vehicles are electrically powered. The two other vehicles also have the same small and manoeuvrable design, but are diesel-powered. The new city bus system will continue to be operated by Wilhelm Welser Verkehrsbetriebe GmbH on behalf of the Upper Austrian Transport Association, which will also supply the electricity required for the electrically powered vehicles from its own photovoltaic system: "With a 408 kWp photovoltaic system at our site in Haid, we can supply all of the green electricity for the six e-buses in Traun," emphasises Managing Director Christa Trixl. With the renewable energy community (EEG), this electricity is also available for the charging stations in the Traun bus garage of Wilhelm Welser Verkehrsvertriebe.
The operation of the new Traun city bus routes is financed two thirds by the city of Traun and one third by the state of Upper Austria.

Timetable on the individual city bus routes
631 Oedt - Traun main square - Traun railway station (Traun line)
Line 631 connects the western district of Oedt with Traun main square and Traun railway station. At the main square there are connections with tram line 4 to/from Linz. At Traun railway station, the timetable for line 631 is coordinated with the Pyhrnbahn trains every hour.
632 Trauner Kreuzung - Traun Steinhumergutsiedlung - Oedt (Oedt line)
Line 632 also starts in the Oedt district and runs via Steinhumergutsiedlung and Siebenbürgersiedlung to the central interchange at Trauner Kreuzung. Tram lines 3 and 4 (Traun - Linz), several regional bus lines and three of the four new city bus lines come together at Trauner Kreuzung. In addition, a specialist retail centre, a large park & ride facility and local shops are located in the immediate vicinity of the stop. Serving the Traun junction is an important new feature of the future city bus system. The city bus did not previously serve this stop.
633 Trauner Kreuzung - St. Martin Bhf - St. Dionysen - Traun Hauptplatz (St. Martin line)
The 633 line serves the north-eastern districts of St. Dionysen and St. Martin, including the St. Martin railway station. The start and end stations of line 633 are Trauner Kreuzung and Traun Hauptplatz, which is why these two most important hubs can be reached from both districts without having to change trains.
634 Trauner Kreuzung - St. Dionysen - St. Martin (St. Dionysen line)
The service is completed by the completely redesigned line 634, which connects the district of Alt-St. Martin, which was previously not served by the city bus, with the district centre of St. Dionysen and Trauner Kreuzung. Several schools, the primary care centre and the sports centre are on the route of this line. All facilities have or will have stops in the immediate vicinity. Lines 634 and 632 will be linked to each other, allowing passengers to remain seated on the bus. This through-connection makes it possible to travel between Alt-St. Martin in the far east of the city and Oedt in the far west of the city via Trauner Kreuzung without having to change buses.
