The Court Challenge Over Germany's Long-Distance Rail Capacity

Germany's state-owned rail group Deutsche Bahn is taking the Bundesnetzagentur to court to block a competition order that would force its infrastructure arm to reserve more track access for rival passenger operators. The company said DB InfraGo would seek fast-track proceedings at the Cologne Administrative Court to test the legal basis, proportionality and practical workability of the regulator's requirements.

The contested decision requires DB InfraGo to allocate at least one quarter of capacity on heavily used long-distance routes to competitors. The regulator says that reservation should ensure at least one rival operator can run services where demand is strongest. The trigger is a complaint from Italian rail company Italo, which plans to enter the German long-distance market from April 2028.

Deutsche Bahn argues the order could make annual train-path allocation more complicated. Operators request specific paths for each timetable period, and long-distance, regional and freight services already compete for limited capacity on the same German network. The Bundesnetzagentur said it was not surprised by the legal challenge and argued that its decision had already considered the company's points.

The regulator stressed that fair competition should bring more choice and lower ticket prices. It noted that DB Fernverkehr still holds roughly 93 percent of the long-distance passenger rail market. Flix, the best-known rival, has also announced an expansion push for 2028 with new trains and connections.

What the Italo Entry Fight Means for Deutsche Bahn and Rivals

Why Deutsche Bahn is resisting the decision

Deutsche Bahn's objection is operational as much as legal. The 25 percent reservation limits its ability to prioritise its own services on the most congested corridors, and it creates a scheduling constraint in a network where long-distance, regional and freight traffic already compete for scarce paths. From DB's perspective, the rule forces it to protect competitor slots even when its own trains are heavily booked.

Italo and Flix are the clear beneficiaries

The agency decision directly supports Italo's planned April 2028 entry by giving it a legal route to secure paths on busy German corridors. Flix's announced 2028 expansion with new trains and connections would also benefit from the same access framework. However, the order lowers entry barriers rather than removing them: the challengers still need rolling stock, staff, timetable approvals and distribution capacity before they can compete effectively.

The regulator's competition logic

The Bundesnetzagentur is framing the case around market concentration. With DB Fernverkehr holding roughly 93 percent of long-distance passenger rail, the agency is using mandatory capacity reservation as a structural tool to open the market. The consumer benefit is only potential: more choice and lower prices depend on whether rivals can convert reserved paths into reliable, commercially viable services.

What to Watch for Rail Operators, Regulators and Passengers

The dispute has different implications for the parties involved.

  • Rail challengers: Italo and Flix should treat the 25% minimum capacity on busy routes as a provisional planning basis, but prepare for the possibility that DB InfraGo's injunction request suspends or delays the order.
  • Deutsche Bahn and its stakeholders: Watch the Cologne Administrative Court ruling. If the regulator's decision survives, DB Fernverkehr will face its clearest structural pressure on its 93% long-distance share since market liberalisation.
  • Passengers and corporate travel buyers: Expect possible new long-distance options around April 2028 if the order is upheld and challengers execute their plans. Ticket prices could become more competitive on the affected routes.

Risk & Opportunity Assessment

Commercial RiskMediumDeutsche Bahn could be required to surrender up to 25% of capacity on high-utilisation long-distance routes while its DB Fernverkehr unit holds about 93% market share, opening room for rivals to win traffic.
Competitive RiskHighItalo's planned April 2028 entry and Flix's announced 2028 expansion directly target DB's concentrated long-distance passenger market, which the regulator has identified as structurally limited in competition.
Regulatory RiskHighDB InfraGo is challenging a binding Bundesnetzagentur order at the Cologne Administrative Court; if the challenge fails, mandatory capacity reservation and related access obligations are likely to be entrenched.
Reputation RiskMediumA state-owned incumbent fighting a pro-competition decision may be seen as protecting a near-monopoly, even though Deutsche Bahn frames its objections around operational complexity and feasibility.
Technology DisruptionLowThe case concerns track access and capacity allocation rather than a new rail technology. New trains announced by challengers are incremental competitive moves, not a technology shock.
Commercial OpportunityHighFor Italo and Flix, mandatory access to busy routes creates a clearer path into the German long-distance market from 2028; for passengers, more competition could mean more choice and lower fares.
