Room to Grow
The Channel Tunnel has a capacity problem, but not the kind most infrastructure projects face. Only about half its available train slots are currently used. That gap has caught the eye of several would-be operators, and Gemini Trains is now the latest to put firm dates on paper. The UK start-up announced it intends to launch a London to Cologne service by 2030, with journey times around four hours. That cuts roughly two hours off the current indirect route, which requires at least one change.
Gemini first floated the idea in 2025, when CEO Adrian Quine framed the tunnel as underused and ripe for competition. The company is not alone in sensing opportunity. Spanish start-up Evolyn, Italy's Trenitalia, and Virgin Trains have all signaled interest in cross-Channel routes, with Virgin eyeing Paris, Brussels, and Amsterdam by the end of the decade. The tunnel, it turns out, has space for ambition - whether the market does is another question.
A Different Station Strategy
Gemini is staking part of its pitch on geography. Instead of operating from London St Pancras, the hub Eurostar has made synonymous with continental rail, Gemini plans to use Stratford International in east London. The company will also stop at Ebbsfleet International and Ashford International, the latter a station that lost its Eurostar service in 2020.
The logic is partly practical. St Pancras is constrained, and Gemini wants to avoid the bottleneck. But the choice also carries risk. Stratford is less central for many London travelers, and while it has good transport links, it lacks the prestige and convenience St Pancras offers. Whether passengers will trade location for potentially lower fares remains to be seen.
The company says introductory one-way tickets to Paris could start at fifty-nine pounds, roughly sixty-nine euros. That undercuts Eurostar's typical pricing, though fares fluctuate. Standard class will include Wi-Fi and ambient lighting; business class adds food and privacy screens. The initial fleet is planned at eight electric trains, each seating 550 passengers.
Speed and Network Plans
The London to Cologne route is part of a broader rollout. Gemini intends to start with London to Paris, including stops at Disneyland Paris and Charles de Gaulle airport, then extend to Brussels. After that, the company has named Frankfurt and Düsseldorf as expansion targets. The Cologne service, if it materializes, would be the longest haul in the initial network.
Four hours from London to Cologne is competitive with flying when check-in and airport transfers are factored in, though still slower than a plane in the air. The appeal hinges on convenience, pricing, and whether travelers see rail as preferable for environmental or comfort reasons. Gemini is betting enough do, especially if the price is right.
Eurostar's Response
Eurostar is not standing still. The operator, which currently carries around twenty million passengers a year, has stated it aims to grow to thirty million. It has committed up to two billion euros for new double-decker Celestia trains from Alstom and has been laying groundwork for routes to Frankfurt and Geneva. A memorandum of understanding with Deutsche Bahn was signed in 2025, signaling intent to expand into Germany.
That puts Gemini in direct competition not just with Eurostar's existing network, but with its expansion plans. The incumbent has brand recognition, established slots at St Pancras, and a head start on regulatory approvals. Gemini has lower costs, a willingness to use secondary stations, and the promise of cheaper tickets.
The question is whether the market can support multiple operators, or whether the tunnel's spare capacity will remain largely theoretical. Other industries have shown that new entrants can force down prices and improve service - low-cost airlines did exactly that in Europe over the past two decades. Rail is more capital-intensive and regulated, but the dynamics may be similar.
What It Means for Travelers
If Gemini and its rivals succeed, cross-Channel rail could become more affordable and more frequent. More operators would likely mean more destinations, more departure times, and pressure on Eurostar to keep fares competitive. The return of service to Ashford could also benefit passengers in Kent who currently face longer journeys to London terminals.
But there are caveats. Start-ups in transport often announce ambitious timelines that slip. Regulatory approval for new train operators is complex, and financing remains a hurdle. Gemini has not yet disclosed funding details or confirmed orders for rolling stock. Until trains are running, these remain plans on paper.
Still, the fact that multiple companies see a business case suggests the market is shifting. Cross-border rail in Europe has been growing, driven by environmental concerns, frustration with airport hassles, and improving infrastructure. The Channel Tunnel, built in the 1990s, was always meant to carry more than one operator. It may finally get the chance.
