Control and safety technology (LST) is the system that ensures trains travel on the right track, stop in the right place, and maintain the correct distance. Signals, electronic signal boxes, turnout drives, axle counters, and cable connections are all part of LST and must function reliably around the clock, in all weather conditions. Klefenz GmbH is an approved DB-qualified specialist company for LST work and carries out assembly and commissioning on the German rail network.
Approval for LST work on the DB network requires supplier qualification from Deutsche Bahn AG and certified specialists. Klefenz meets both requirements: the company is prequalified for the relevant LST product categories and employs trained personnel familiar with all technical and safety regulations. All LST work is fully documented and approved in accordance with defined processes in coordination with the responsible operator.
Track construction and control and safety technology are intertwined in many projects: turnout upgrades require the integration of new turnout drives into the signal box, new track systems require signals and axle counters, and DB Digital Rail installs new digital interlocking technologies on existing lines. Klefenz coordinates these interfaces between track construction and LST, offering both from a single source — a clear advantage for clients who want to avoid the coordination costs of managing multiple specialist companies.
Klefenz operates a dedicated branch in Germersheim to carry out LST projects on routes in southwestern Germany. This branch serves as an operational base for our LST teams, enabling short travel times, quick responses, and direct contact with local DB project management. Contact us if you are looking for a qualified LST specialist for your project.
Whether it is a demanding construction project or a professional perspective – Klefenz stands for experience, reliable collaboration and a clear commitment to quality. If you would like to realise a project or become part of our company, we look forward to speaking with you and taking the next step together.
