Title:
Abstract:	The Koralm Tunnel (length 33 km) crossing the eastern Alps is part of the Koralmbahn line and one of the longest rail tunnels in the world. The installation of railway equipment in the tunnel is due to start soon and it is particularly important to now make current decisions considerung future developments and demands. In particular the conflicting goals of the scheduling horizon of the construction permit process nearly 20 years ago, the 150-year design horizon and the rapid development of electronics, data processing and telematics have to be considered. Experience of operation of long rail tunnels confirms that despite all logistical efforts, the maintenance of railway equipment leads to a great expense of time and finance and also to restrictions of the line availability for operations. Mit einer Länge von 33 km zählt der Koralmtunnel als östlichste Alpenquerung und Teil der Koralmbahn zu den längsten Eisenbahntunneln der Welt. Gegenwärtig steht man vor dem Beginn der bahntechnischen Ausrüstung des Tunnels, und es gilt in besonderem Maße, aktuelle Entscheidungen für die Zukunft vorausschauend zu treffen. Insbesondere muss der Zielkonflikt der terminlichen Betrachtungshorizonte von beinahe 20 Jahre zurückliegenden Baugenehmigungsverfahren, 150 Jahre Dimensionierungshorizonten und rasanten Entwicklungsgeschwindigkeiten im Elektronik-, Daten-, und Telematikbereich überwunden werden. Die Erfahrungen aus dem Betrieb langer Eisenbahntunnel bestätigen, dass trotz aller logistischen Anstrengungen die Instandhaltung [3] der bahntechnischen Ausrüstung zu großen zeitlichen und finanziellen Aufwänden und einhergehend auch zu Einschränkungen der betrieblichen Streckenverfügbarkeit führt.
