Europe is gearing up for a rail revolution that could redefine cross-border travel — and Copenhagen is set to be one of its biggest winners. Under a new EU plan unveiled this week, passengers could soon make the trip from Copenhagen to Berlin in just four hours, almost halving today’s travel time.
The initiative is part of a broader European Commission effort to accelerate the development of high-speed rail across the continent. The goal is ambitious: to connect major cities with fast, reliable, and sustainable train services that make flying on short routes unnecessary. If all goes to plan, the Copenhagen–Berlin route could be ready by 2030.
From Seven Hours to Four
Today, the journey between the Danish and German capitals takes around seven hours — a route that, for most travelers, remains faster by plane. But once new high-speed lines are completed and key infrastructure projects come online, rail could become the preferred choice.
The EU envisions sleek, next-generation trains traveling at up to 300 km/h, offering shorter travel times, comfortable cabins, and far less environmental impact. The project has already attracted international attention, with The Guardian calling the Copenhagen–Berlin link “a symbol of Europe’s green mobility ambitions.”
The Fehmarn Connection
Central to this plan is the Fehmarn Belt Fixed Link, a massive underwater tunnel connecting Denmark and Germany. Once completed, the 18-kilometer link will cut hours off travel times and form a key section of the Scandinavian–Mediterranean Corridor, one of Europe’s most important transport routes.
Originally expected to open in 2029, the project has faced technical delays, but it remains a cornerstone of the EU’s strategy to connect northern and southern Europe by high-speed rail. The corridor will also benefit from other major upgrades — including the Brenner Base Tunnel between Austria and Italy, which will drastically reduce journey times through the Alps.
Linking the Continent — From Sicily to the Baltics
Europe’s railway renaissance doesn’t end in Central Europe. Farther south, the long-discussed Messina Bridge will finally connect mainland Italy with Sicily. The suspension bridge, expected to be completed by 2032, will span about 3.3 kilometers — more than twice the length of Denmark’s Great Belt Bridge — and give the Scandinavian–Mediterranean corridor its final southern link.
To the east, the Rail Baltica project is moving forward, promising to unite Estonia, Latvia, and Lithuania with the rest of Europe’s high-speed network. And in the west, a new line between Lisbon and Madrid aims to reduce travel time from ten hours to just three by the end of the decade — just in time for the 2030 FIFA World Cup hosted by Spain, Portugal, and Morocco.
Investing in the Future of Travel
These projects are supported by the EU’s Connecting Europe Facility (CEF) fund, which helps finance infrastructure seen as strategically vital for the continent’s economic and environmental goals. But money alone won’t make it happen — regulations must also change.
To make cross-border rail travel simpler, the EU plans to overhaul ticketing systems, allowing passengers to book international journeys with multiple operators in one step. It also aims to open routes to new competitors, streamline licensing for train drivers across borders, and promote research into high-speed trains capable of handling Europe’s varied climates and long distances.
When complete, the network will put Copenhagen in the heart of a transformed European rail system. Trips to Berlin will take four hours, Stockholm just under that, and onward travel to southern Europe will become faster and smoother than ever before.
