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. The study, for which the EU granted funding in the following December, 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 15 minutes between the two city centers. Work on the study is expected to continue until 2020.
In May 2018 the Oresundsmetro 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. Capacity constraints are expected on the Oresund Line rail services once the Fehmarn Belt Fixed Link is completed, and the €4 billion metro proposal would ease this bottleneck.
