Plans for an incredible new train line that connects 39 cities have been revealed.

21st Europe has proposed the ambitious Starline network - a high-speed, Tube-style aiming to streamline European travel.

It will reportedly be publicly funded and run by national rail companies, overseen by a proposed Rail Authority - a new EU body that would be responsible for the system's coordination and expansion.

The think tank estimates that the will decrease short-haul flights by 80% and offer travel 30% faster than cars and traditional rail services, with trains operating at up to 250 mph. This means you could get from Helsinki to Berlin in three hours.

The 13,700-mile network seeks to connect 39 destinations in countries. It will have lines linking Naples and Helsinki, Lisbon and Kyiv, Madrid and Istanbul, and Milan and Oslo. The train will also make stops in London, Paris, Rome, Zurich, and Vienna, among 39 total locations across more than a dozen countries.

All-new stations would need to be built outside each city and double as 'cultural hubs' with restaurants, shopping, concert halls, museums, sports venues and links to urban transport systems.

The yellow and blue carriages will not be divided by classes but by spaces for different needs, such as quiet zones for working and family-friendly sections.

21st Europe's Starline network hopes to reinvent the continent's "fragmented, uneven, often slow" rail infrastructure and introduce ultra-fast connections to rival air travel.

"A truly integrated rail system is no longer just a matter of convenience; it's a strategic necessity for Europe's resilience in the 21st century," the think tank states.

"Designed like a metro system, [Starline] changes how Europeans perceive their own continent - not as a collection of distant capitals, but as a single, fast-moving network where every connection, whether for people or goods, is within easy reach."

"From the golden age of night trains to today's 400,000+ Interrail users annually, the desire for open, accessible travel is clear," the think tank said. "Yet, despite public demand, cross-border travel remains fragmented, slow, and expensive."
