Rail Construction

Klefenz GmbH is a certified partner of Deutsche Bahn AG, performing track construction on main and branch lines—from maintenance and sleeper replacement to new track bed installation during ongoing operations.

Decades of expertise in track construction

Track construction is the discipline for which Klefenz is known throughout the region. As a qualified partner of Deutsche Bahn AG, the company carries out track construction on main and branch lines, utilizing certified personnel, road-rail vehicles, and experience gained from hundreds of projects across the DB network. Core services include sleeper replacement, rail renewal, new track systems, ballast profiling, and the maintenance of existing line sections.

What sets Klefenz apart from other track construction companies is our ability to bundle multiple measures within a single track possession. This minimizes operational disruption and saves the client the costs associated with multiple possessions—an advantage that is directly reflected in the project outcome.

All track construction is carried out in compliance with DB safety standards and track construction guidelines. Klefenz is a qualified supplier for the relevant product categories at Deutsche Bahn AG and holds the necessary certifications for track construction on the rail network. This includes working in close proximity to active rail operations, as well as during night and weekend shifts within defined track possessions.

Our track construction services

Sleeper replacement on main and branch lines is just as much a part of our service range as rail renewal, new track installation for industrial and connecting railways, ballast profiling with specialized machinery, and the repair of damaged areas in the track bed, such as mud spots in the ballast. Klefenz operates its own fleet of road-rail vehicles and track construction equipment, ensuring independence from external equipment rentals.
