LEONHARD WEISS GmbH & Co. KG is a German construction firm based in Göppingen, in the state of Baden-Württemberg. As a family-owned business with a history spanning more than 125 years, it ranks among Germany's larger construction companies. The company operates through three main segments — roads and network construction, rail infrastructure, and engineering and turnkey construction — delivering integrated services across civil, industrial, and infrastructure projects. This structure supports a workforce capable of handling large-scale, multi-disciplinary endeavors and positions the firm to manage complex projects end-to-end. Its primary customers are organizations seeking substantial infrastructure developments in road, rail, and related turnkey solutions, with a focus on long-term project delivery and coordination across trades. In March 2026, LEONHARD WEISS announced a partnership with European Loc Pool AG to add a EURO9000 hybrid locomotive to its rail fleet, reflecting ongoing investments in equipment and rail operations.
