In September 2011, the local governments in Copenhagen and the neighbouring Malmö in Sweden announced that they were seeking European Union funding to study a potential metro line under the Øresund to the neighbourhood of Malmö Central Station, providing faster trips and additional capacity beyond that of the existing Øresund Bridge.
[3] The study, for which the EU granted funding in the following December,[4] will consider both a simple shuttle between the two stations and a continuous line integrated with the local transport networks on each side, and they anticipate a travel time of approximately 20 minutes between the two city centers.
[6][7] In May 2018 the Øresund Metro Executive was announced, formed of representatives from the two cities, industry and researchers, to explore the proposal to link Copenhagen and Malmö via a driverless metro system, with travel time of around 20 minutes compared to 35 minutes by train.
[8] Capacity constraints are expected on the Øresund Line rail services once the Fehmarn Belt Fixed Link is completed, and the €4 billion metro proposal would ease this bottleneck.
The line is planned to have capacity for 36 trains per hour in each direction, a maximum speed of 120 km/h (75 mph) and be connected to the existing Copenhagen Metro system.
