Unrestricted work permit:The foundation construction train is ready for nationwide deployment

Our foundation construction train (GGZ) has reached a major milestone: As of July 3, 2025, it has received the one-year work permit from DB InfraGO. This allows the GGZ to operate without route restrictions and serve construction sites across the entire German rail network for one year.

The approval process was challenging, but the intensive efforts of the consortium (Techne-Kirow & RTG Bauer) have paid off: All documents have been completed and officially submitted to the Federal Railway Authority (EBA). While the EBA is now working on granting the permanent approval – expected within the next two to four months – we can already announce today: What once began as a vision is now a reality – the GGZ is ready for nationwide deployment.
