Why is there actually a German railway station in the middle of Basel?

Anyone getting off at Basel Badischer Bahnhof today might initially believe they had arrived at an ordinary Swiss railway station. Swiss trains stop here just as German regional and long-distance services do, Basel trams run in front of the building, and the address is Schwarzwaldallee 200 in Basel. At the same time, the station clearly presents itself externally as a DB station. This combination is not a historical curiosity without significance: According to Deutsche Bahn, around 22,000 travellers and visitors use the transport hub every day. The renovation of the listed reception building was only completed at the end of 2025.

The explanation for this unusual status goes back to the year 1852. At that time, the Swiss Confederation and the Grand Duchy of Baden concluded a state treaty allowing the Baden State Railways to continue their line across Swiss territory. Baden undertook to build, maintain and operate the railway lines on Swiss soil in the same way as the lines in its own country. The historic treaty still forms a basis for the special status of the German railway facilities in Basel today.

As early as 19 February 1855 railway service began from Haltingen to Basel. However, the first Badischer Bahnhof was not yet where travellers know it today, but closer to what is now Messeplatz. At first, there was only a temporary building there, followed later by a larger station. As Basel grew, however, the railway areas increasingly became an obstacle to the city's development. Around the turn of the century, Basel and Baden therefore agreed to relocate the facilities.

The present-day Badischer Bahnhof was ultimately built on Schwarzwaldallee and entered service in 1913 . The striking reception building was designed by the architects Curjel and Moser and is now a listed monument. What is interesting is how large the entire project was at the time: The German railway facilities shaped a significant part of northeastern Basel and became an important link between the German Rhine Valley Railway, the High Rhine Railway and the Swiss rail network.

And now comes the actual special case. In a detailed response on the station's legal status, the government council of the Canton of Basel-Stadt expressly stated: “Badischer Bahnhof belongs to the Federal Republic of Germany.” At the same time, the Basel government made it equally clear that the entire area lies on Swiss sovereign territory . This exact difference is crucial.

Basel Badischer Bahnhof is therefore not a German enclave. Anyone entering the station does not legally leave Switzerland. Swiss sovereign rights expressly remain in force insofar as the historical state treaties do not provide special rules. The Basel-Stadt cantonal police can, for example, operate throughout the station grounds, and anyone committing a crime there is generally subject to Swiss criminal law. Private businesses in the station are also liable for tax in Switzerland.

At the same time, special German regulations apply to parts of railway operations. That is precisely why the station is so unusual from a legal perspective. The agreements between Germany and Switzerland provide that the German side operates and maintains its railway facilities in Switzerland. Swiss sovereign rights remain in force, while German railway regulations are relevant to certain operational matters. So one is not simply either “in Germany” or “in Switzerland”—depending on the area concerned, different historical agreements and national regulations apply.

This separation was particularly visible for decades in customs matters. Because of its history, the station has a special customs status. Travellers arriving from Germany and continuing within the German railway connections could use parts of the station without entering the Swiss customs territory in the conventional sense. Historically, there was even a recognisable transition inside the station between the German customs zone and the rest of Swiss territory.

Since Switzerland joined the Schengen Area at the end of 2008, however, the border has seemed far less remarkable to travellers. Systematic identity checks were abolished. This also made it possible, for example, to permanently open a southern entrance to Badischer Bahnhof to travellers in 2014, after it had previously been largely closed for customs reasons. The historical special regulations still exist, but in everyday travel they are much less visible than before.

The range of train services also shows that the station has long ceased to be an exclusively “German” station in practical terms. German and Swiss services meet here directly. The selected article image makes this special feature particularly clear: Beneath the unmistakably German station sign “Basel Bad Bf” there is a vehicle bearing SBB markings. The station is therefore one of those places where the two railway systems do not merely meet at a border, but literally use the same platforms.

The special status is also more than a relic that is destined to disappear at some point. Germany and Basel continue to work together on railway infrastructure in the vicinity of Badischer Bahnhof. Existing state treaties continue to provide the basis for cross-border projects. The connection towards Germany also plays an important role in the expansion of the Rhine Valley Railway and the further development of the Basel rail hub. Basel is also planning, in the long term, a better underground connection between Basel SBB and Badischer Bahnhof.

Today, Basel Badischer Bahnhof is therefore a truly unique piece of European railway history. The station stands in Switzerland, Swiss state sovereignty continues to apply—but the facility belongs to Germany and is operated as German railway infrastructure. A state treaty from 1852 thus created an arrangement that still works more than 170 years later.

And perhaps that is precisely what makes it so special: The border cannot be drawn with a simple line at Badischer Bahnhof. You can stand on Swiss soil, look at a DB station sign and be on land belonging to the Federal Republic of Germany—without leaving Switzerland at all.

Did you know that Basel Badischer Bahnhof actually belongs to Germany? Would you have thought that such an old state treaty still shapes everyday railway operations today? And do you know of any other stations where national borders and ownership structures are intertwined in similarly unusual ways?
