Rhomberg Sersa Bahntechnik GmbH

What Rhomberg Sersa Bahntechnik GmbH does

Rhomberg Sersa Bahntechnik GmbH is a family-owned Austrian railway infrastructure general contractor (Totalunternehmer) headquartered in Bregenz and Vienna, operating under the Rhomberg Sersa Rail Group brand alongside wholly-owned subsidiaries in Switzerland, Germany, Australia, the Nordics, the UK, Ireland, and North America. The company delivers the full lifecycle of rail infrastructure projects — planning, project management, mechanized and manual track construction, fixed/slab track (Feste Fahrbahn) systems, tunnel rehabilitation, electrotechnical equipment, track-bound noise protection installation, and construction site logistics — for state-owned mainline railway operators, public transport authorities, and industrial customers with private rail networks.

The company's core technology centers on high-performance Feste Fahrbahn slab track systems, supported by a dedicated RSRG Showgleis exhibition facility and a modern mechanized track-construction fleet; tunnel rehabilitation and digital rail services for construction, operation, maintenance, and servicing round out the technical offering. Revenue is generated through project-based general contracting (multi-year contracts with public rail operators), supplemented by equipment and machinery sales/rental, construction materials trade, machine maintenance services, and site logistics/provisional works. Go-to-market is direct enterprise sales targeting public rail infrastructure buyers, supported by country-specific websites, trade fair participation, and detailed project reference marketing.

The Bahntechnik GmbH legal entity sits within the Rhomberg Sersa Rail Holding GmbH group structure and operates as the Austrian project business arm, with sister entities handling Swiss, German, Australian, and Nordic operations. The Sersa Group was previously acquired by Rhomberg, and in 2022 the combined operations were rebranded as Rhomberg Sersa Rail Group. Customer relationships are anchored in multi-year framework agreements and project tenders with marquee public clients including ÖBB-Infrastruktur, SBB, BLS Netz AG, and Rhätische Bahn, while the company pursues adjacent growth through the Railtozero sustainability initiative and the Digital Rail Services platform.
