The tunnel, which is part of Spoorzone Delft (Railway Zone Delft), consists of an East tube and a West tube, both fitted with 2 separate rail lines. The operating system is the technical heart of the tunnel, from where all the electromechanical systems for safety measures and audio and video communication are operated and controlled.

In order to meet the high availability requirements, the Siemens operating system is fully implemented in duplicate, so that rail traffic can continue to run even if there is a malfunction. The maintenance activities include configuration management, incident management and preventative and corrective maintenance. The service processes have been configured to fulfill the operating system’s high reliability and availability requirements. The contract will be implemented by the Outsourced Services unit of ICT Group, which specializes in software life-cycle management and Asset Management in addition to the above-mentioned service activities.
