Maintenance of Øresund Landanlæg - road and railway
The tasks are outsourced
A/S Øresund has outsourced all operational and maintenance tasks on the Øresund motorway. The main tasks include the operation and maintenance of the Tårnby tunnel, the pumping stations, signaling systems and other mechanical and electrical installations. In addition to this are general road operations including inspections, winter services, green maintenance and remedial action folllowing an accident. A number of operational contracts have been entered into in collaboration with the Danish Road Directorate.
The facilities are monitored around the clock
Sund & Bælt's objective is for the company's motorway sections are open around the clock throughout the year, and that traffic flows smoothly and safely with a high level of service and as few disruptions from operations and maintenance as possible. Traffic accidents are prevented through proactive efforts, and it should be at least as safe to drive on the company's sections as on other motorways in Denmark.
An SCADA system (Supervisory Control and Data Acquisition) monitors ventilation, lighting, traffic management and operational status in the Tårnby tunnel and the water level of the groundwater along the facility.
Operation of the Øresund line
On 1 September 2015, A/S Øresund took over maintenance of the Øresund line from Banedanmark. As on the motorway, external contractors operate and maintain the line.
The Øresund line should be safe - both for those who use it and for those who work on it. Traffic on the Øresund line is monitored and controlled from the regional remote control centre at Copenhagen Central Station (RFC Kh), where staff have an overview of the traffic and the ability to intervene in the automatic remote control. Information for travellers also originates from here.
The Øresund line is equipped with a modern, fully electronic interlocking system, Ebilock 850. Together with ATC (Automatic Train Control), the interlocking system provides users with maximum security and the rail line with significant capacity. The interlocking systems are usually operated from the remote control centre at Copenhagen Central Station (RFC Kh). For handling faults, local service areas have been set up for the interlocking systems at Copenhagen Airport and at Kalvebod.
ATC functions as an adjunct to the interlocking and line block system. ATC transmits information from the interlocking system to the train - and vice versa. The transmitter and receiver are mounted on the train and at the lineside respectively.
Until 2021, Banedanmark will be replacing the signaling systems on the railway network across Denmark in favour of the common European system ERTMS level 2, which eliminates the majority of the external signals in favour of signals directly into the driver's control panel. This also applies to the Øresund line, and will generally mean greater operational safety, punctuality and capacity for more trains on the railway.
