Expert Opinions


Changes, new developments and alterations require an understandable assessment with regard to the correct function principle.


The assessment is conducted in line with recognised technical regulations and safety judgements.


The wide range of examined objects primarily refers to interlocking technology (including older technologies) and its components, level crossings and level crossing protection systems, automatic train control systems such as ETCS and others. Audits and expert opinions on processes of planning, project planning, production and verification are conducted.


The CERSS Kompetenzzentrum Bahnsicherungstechnik renders expert opinions on various concerns of railway safety technology. We focus on the proof of safety and function, project inspections and accident reports.
