BBW Group - Track Construction with Passion

Bahnbau Wels has been dedicated to the construction and maintenance of infrastructure facilities in the railway sector for more than 70 years. This passion is shared with its five subsidiaries in the BBW Group, which are all active in different areas of track construction. As part of the Rhomberg Sersa Rail Group, it can access an almost comprehensive portfolio of services in the areas of railway construction, equipment and service. This allows the business to offer its customers tailor-made solutions for each particular project. 


Whether in mechanical track construction, commercial track construction, overhead line construction, electrotechnical equipment or control and safety technology - BBW Group has been convincing its customers for many years with competence and performance coupled with innovative ideas - even beyond Austria's borders. The group's mechanical track construction has been equally successful in Austria and throughout Germany for decades. The commercial track-laying units have also been welcome partners on construction sites in southern and south-western Germany for several years and are highly appreciated for their performance potential in this region too. 


In addition to the classic track construction sector, the BBW Group also provides services in the maintenance of special vehicles and freight wagons. In this segment, the range of services extends from maintenance in all maintenance stages, modernisation of track construction machines to complete overhauls. 

Did you know...

...that Bahnbau Wels was the first business in Austria to use mechanised track-laying machines and thus laid the foundation for mechanised track-laying in Austria?

Modernisation Port Railway Station Aschaffenburg

The port railway station at bayernhafen Aschaffenburg is undergoing extensive modernisation and is also fitted with new security technology. Bahnbau Wels was commissioned with the complex civil engineering and track construction work for this important logistics hub in the region Bayerisch RheinMain. 


Since May of this year, Bahnbau Wels has been implementing this project in close coordination with the client Bayernhafen GmbH & Co. KG. Based on the design planning, Bahnbau Wels also provided the recording and re-routing of the track systems for the new port railway station. 


The entire project can only be implemented in individual, pre-coordinated construction phases so that the construction work can be carried out while the port railway station remains in operation. In addition to the extensive earthworks and track construction work, the underground cabling work will also be carried out by Bahnbau Wels itself. 


The dedicated construction site team on site is the assurance of rapid construction progress and ongoing coordination with the client. Thanks to the trust shown and the solution-oriented collaboration on the part of bayernhafen, even major joint challenges, such as the current issues regarding material availability and the tense pricing situation for superstructure materials, can be mastered in the best possible way.
