Sicherheitsnachweis Dolderbahn
Systembetrachtung nach SN/EN 50126
Für diese Schnittstelle zwischen Domino und Ansteuerung der Weiche wurde die Zulassung des Bundesamtes für Verkehr (BAV) benötigt. Dazu musste mittels Sicherheitsnachweis gezeigt werden, dass die Schnittstelle alle möglichen Szenarien beherrscht und zu keinem Zeitpunkt unkontrollierbare Situationen auftreten können. Für den Sicherheitsnachweis wurden die Domino-Steuerung und die Ansteuerung mit der Weiche in die Betrachtung eingeschlossen. Als Ausgangslage dienten alle möglichen Zustände des Gesamtsystems und deren Auswirkungen auf die einzelnen Komponenten.
Eine sehr wichtige Analyse bei einem Sicherheitsnachweis einer derartigen Anlage ist die Untersuchung der Kabelverbindungen im Hinblick auf Kabelunterbrüche und Kurzschlüssen zwischen einzelnen Adern. Es muss nachgewiesen werden, dass alle diese Fälle von der Schnittstelle beherrscht werden und eine entsprechende Störung ausgelöst werden kann.
Der Sicherheitsnachweis diente als Basis für den Gutachter, der die Schnittstelle anschliessend dem BAV zur Zulassung empfohlen hat.
Der Umbau der Dolderbahn wurde im Dezember 2004 abgeschlossen und die Bahn funktioniert inklusive der Weiche seit Beginn einwandfrei.

Dazu musste mittels Sicherheitsnachweis gezeigt werden, dass die Schnittstelle alle möglichen Szenarien beherrscht und zu keinem Zeitpunkt unkontrollierbare Situationen auftreten können. Für den Sicherheitsnachweis wurden die Domino-Steuerung und die Ansteuerung mit der Weiche in die Betrachtung eingeschlossen. Als Ausgangslage dienten alle möglichen Zustände des Gesamtsystems und deren Auswirkungen auf die einzelnen Komponenten.
Eine sehr wichtige Analyse bei einem Sicherheitsnachweis einer derartigen Anlage ist die Untersuchung der Kabelverbindungen im Hinblick auf Kabelunterbrüche und Kurzschlüssen zwischen einzelnen Adern. Es muss nachgewiesen werden, dass alle diese Fälle von der Schnittstelle beherrscht werden und eine entsprechende Störung ausgelöst werden kann.
Der Sicherheitsnachweis diente als Basis für den Gutachter, der die Schnittstelle anschliessend dem BAV zur Zulassung empfohlen hat.
Der Umbau der Dolderbahn wurde im Dezember 2004 abgeschlossen und die Bahn funktioniert inklusive der Weiche seit Beginn einwandfrei.
