Herausforderung Instandhaltung Koralmtunnel im Spannungsfeld betrieblicher Verfügbarkeit und Anlagenmehrung

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.
