Surge protection in electronic interlockings and level crossing systems

May 2024 | Editor

Both modern electronic interlocking systems (ESTW)and level crossing systems (BÜSA) have many widely distributed, decentralised electronic components and therefore long cable runs. In the worst-case scenario, overvoltage-related transient couplings via the external system can disrupt or even destroy the centralised control electronics. This is an unacceptable situation for train traffic. Deutsche Bahn AG (DB) Guideline 819.0808 sets out specific requirements for the planning of surge protection concepts for control and safety technology (LST)....
