ZEFERINO

What ZEFERINO does

Zeferino SA is a Swiss railway construction and maintenance services company headquartered in Vallon, Canton of Fribourg (Switzerland), founded in 2020, operating across French-speaking Switzerland (Suisse romande). The firm provides railway track construction, modification, track assembly, maintenance, rehabilitation, and turnkey project delivery to institutional clients — including Swiss Federal Railways (SBB) and regional transport operators (TPF, Mob, TPC, MBC, Travys, TMR, LEB, TL) — as well as to private construction and engineering firms (Colas, Implenia, Vanoli, Groupe JPF, Grisoni, Gruner, Sersa, EFSA) and government entities (Armasuisse). The company reports a portfolio of 20+ institutional and private clients.

Zeferino's service platform rests on an owned fleet of specialized railway equipment — Rail-Route dumpers and excavators, MB8 ballast tamping groups, ballast brushes — operated by OCVM10-certified machine operators and supervised by personnel holding the Swiss federal patent for railway construction supervision (Brévet fédéral de contremaitre voie ferrée). Adjacent offerings include height work, safety supervision for SBB and private networks, equipment and tooling supply, personnel reinforcement for railway sites, salage/deneigement for quays and parking, patrol inspections, and Établissement d'ETF services. The company frames its offering as turnkey railway construction site delivery.

Revenue is generated via project-based, quote-driven B2B contracts awarded through direct sales engagement with public transport authorities, regional operators, and construction companies; pricing is custom per project scope and contract cadence spans multi-year periods. Go-to-market is sales-led, with referral and direct-tender pipelines and a minimal digital presence limited to a LinkedIn page and the corporate website. Zeferino SA is a privately-held Swiss private limited company with no parent, no public ticker, and no disclosed funding rounds or ownership structure.
