Track construction is at the heart of our work. We deliver construction projects on main lines, branch lines and industrial tracks across the full range of services: railway superstructure, trackside civil engineering, trackside cable construction, signalling and control technology, as well as sewer inspection and sewer cleaning in railway environments. As a company prequalified in accordance with Deutsche Bahn requirements, we understand the importance of possession closures, safety regulations and tight construction windows for successful execution.
You receive all track-related trades from a single source. Instead of having to coordinate several subcontractors, you benefit from our own teams and our own machinery fleet. We plan, build and hand over projects on schedule and in accordance with applicable Deutsche Bahn regulations. Get to know our individual services in detail or submit your project inquiry directly.

Whether you have a project inquiry, an application or a general question – we are personally available for you. Write to us, call us or visit us directly in Waldshut-Tiengen. You will receive a prompt response and a dedicated contact person who will follow up on your request.
Track construction is the invisible foundation of every high-performing rail network – from ICE main lines to industrial sidings at production plants. Requirements for construction execution, safety and adherence to schedules are higher here than in almost any other area of transport infrastructure. This is exactly where our strength lies: Klefenz is a construction company specialised in railway construction, with many years of experience in delivering demanding track construction projects for Deutsche Bahn, municipal transport companies and private rail siding operators across the DACH region.
Our team of more than 200 employees combines railway-specific expertise with the discipline required for work on active rail infrastructure. Whether track renewal, switch refurbishment, trackside civil engineering or the construction of a new siding: with Klefenz, you have a track construction partner who understands what the availability of rail infrastructure means for your operations.
