Bybanen: Renaissance of the tram in Bergen
After 45 years with no rail-based local passenger transport, the Norwegian town of Bergen is using trams again in order to cope with the rising volume of traffic: the Bybanen. Work has been progressing on the rail network for Line 1 measuring 18.2 kilometres in total, since 2007. The Braunschweig company, BBR Verkehrstechnik, has been commissioned to set up the signalling systems.
The first tram was operating in Bergen as early as 1897. But it was soon superseded by the car. The subject of trams only became news again in the 1990s. Two lines were planned with a total length of 40 kilometres. Line 1 with 18.2 kilometres connects the town centre with the airport to the south, and Line 2 provides a link between north and west. Construction work on the first section of Line 1 began in 2007. The third and final section has been under construction since completion of the second section in 2013. It was officially opened on 15.08.2016 and approved for passenger transport.
BBR successful in Norway
The signalling system for the rail network in Bergen comes from Braunschweig, from BBR Verkehrstechnik. Taking into account strict EU regulations – particularly the CENELEC standards – and further Norwegian standards, the customer was provided with individually tailored products. Additional requirements and changes were requested on the basis of the experience gained from the first section of the project – and BBR responded proactively. The points positions and trackside stop/proceed signals have been designed in LED matrix technology, and the BBR operator computers in the control room deliver all the current data relating to the particular line to the EFACEC control system. PZB600-M track magnets were fitted as an intermittent train control system due to the limited visibility in tunnels. These magnets can be relied upon to trigger automatic braking if a stop signal is overlooked. The enormous growth of the tram network was taxing the Kronstad depot to its limits. For that reason, a further depot for 50 trams is being created in Kokstad to the south which will also be controlled using technology from the transport specialists from Braunschweig.
