Sersa Group AG (Schweiz)

What Sersa Group AG (Schweiz) does

Sersa Group AG (Schweiz) is the Swiss operating entity of Rhomberg Sersa Rail Group (RSRG), a privately held, family-owned provider of rail construction, maintenance, and digital asset management services headquartered in Zurich. The group was formed in 2012 from the merger of Sersa Group (founded 1948) and Rhomberg Rail, and remains controlled by the Rhomberg and Schnyder families across multiple generations. Through 17 legacy subsidiaries being consolidated under a unified RSRG brand, the group delivers services across track construction and renewal, overhead catenary (electrification) systems, signaling, and civil structures, and operates across nine or more markets including Austria, Switzerland, Germany, the UK, Ireland, Australia, North America, and the Nordics.

Sersa's technology stack spans both physical infrastructure and an emerging digital layer. The Q-tainer product provides rail asset management with AI capabilities built on Microsoft Azure, and the group has deployed the SPOT quadruped robot equipped with LIDAR for automated track inspection. These sit alongside long-standing ECM (Entity in Charge of Maintenance) certifications under EU regulation, ISO quality certifications, and established safety protocols that meet the qualification standards of major European rail operators. The combination of certified maintenance capability and digital instrumentation positions the group as a hybrid industrial-services / rail-tech provider rather than a pure civil contractor.

The business model is primarily project-based and framework-contract based: revenue is generated through multi-year master service agreements with national rail operators (Deutsche Bahn, ÖBB, SBB and equivalents in other served markets) and through participation in major capital programs such as the Koralmtunnel (EUR 270M contract value), Semmering Base Tunnel, Gäubahn, and the Cottbus ICE facility. Pricing is anchored in unit rates, mobilization fees, and milestone-based project billing typical of rail services work, with an emerging recurring component from digital subscriptions and data services offered through Q-tainer. The Swiss AG entity shows 22 employees, while the consolidated group operates at materially larger scale; revenue is not publicly disclosed due to private family ownership.
