A direct Luxembourg-Saarbrücken-Mannheim train edges from idea to study, but not before the mid-2030s

A long-sought direct rail link from Luxembourg eastward into Germany is, for the first time, backed by a formal study saying it can be built. But the same study makes clear that commuters and travellers hoping to board a direct train to Mannheim will be waiting until at least the middle of the next decade.

According to a joint communiqué from Luxembourg's Ministry of Mobility and Public Works, a feasibility study commissioned by four Greater Region partners — Luxembourg, the German Länder of Saarland and Rhineland-Palatinate, and France's Grand Est region — has concluded that a direct Luxembourg-Saarbrücken-Mannheim railway is achievable, while spelling out the obstacles still in the way.

The study finds a direct Luxembourg-Saarbrücken-Mannheim rail link feasible in principle, while identifying technical, infrastructural, legal and financial challenges.

What the study actually says

The findings were presented on Friday 6 February 2026 at a working meeting in Luxembourg hosted by Mobility Minister Yuriko Backes. Around the table were Saarland's Petra Berg, Minister for the Environment, Climate, Mobility, Agriculture and Consumer Protection; Michael Hauer, Rhineland-Palatinate's state secretary for climate protection, environment, energy and mobility; and Evelyne Isinger, a Grand Est regional councillor representing the region's president.

The communiqué is blunt about the timeline. Establishing a direct connection as a regular regional service, it states, "requires a longer preparation period and will only be possible, with the agreement of all partners, from the middle of the 2030s at the earliest." As Chronicle.lu notes, that horizon is also contingent on federal funding being available.

Quicker fixes on the table

Aware that the mid-2030s is a long way off, the four partners agreed to look at shorter-term options. Those include an in-depth analysis of occasional long-distance connections and a study of extending certain existing long-distance services — for example, running a service as far as Saarbrücken. They also agreed to set up a technical working group for regular exchanges on best practices, lessons learned and questions of public transport safety.

The political backdrop is a labour market that increasingly spills across borders. According to the joint communiqué, 276,360 people crossed borders each day in 2024 to reach their workplaces in the Greater Region, the vast majority of them working in the Grand Duchy. The partners noted that no other region in the European Union counts as many cross-border workers.

A push toward Berlin

Momentum has continued since February. Paperjam reported on 31 May 2026 that the Luxembourg-Saarbrücken-Mannheim study was being finalised, and that Backes had used talks "this week" with Germany's federal transport minister, Patrick Schnieder, to press for better German rail connections. The destinations discussed included Mannheim and Cologne, the latter reachable via the Eifel line through Trier.

Schnieder, a CDU politician, has held the federal transport portfolio in Chancellor Friedrich Merz's government since 2025, succeeding Volker Wissing — making him a key interlocutor for any cross-border project that depends on German infrastructure decisions and federal money.

For now, the eastward axis remains Luxembourg's weak point. Rail capacity toward Germany has long trailed the better-developed French and Belgian routes, and the new study, while encouraging, confirms that closing that gap will be a project measured in years rather than months.
