 Malmö became the centre of the new Öresund train regional railway system spanning eastern Denmark and much of southern Sweden, which in 2009 became integrated with local buses and trains in most of its service areas.The trains were, however, forced to reverse direction in Malmö’s terminal station, creating delays for anyone travelling to Denmark from Lund and beyond, and restricting the frequency of service, as each train had to both enter and leave Malmö by the same tracks, taking up space in between.This situation was solved with the opening of the City Tunnel in December 2010, finally allowing through traffic.
