Cologne

Cologne developed as a major transit junction on the Rhine, with Köln Hauptbahnhof functioning as one of Germany’s busiest rail terminals and a key node on high-speed rail corridors connecting Germany to France, Belgium, and the Netherlands. The station sits at the center of the city, where long-distance services on the Thalys network pass through alongside regional and intercity trains. Cologne’s position on the left bank of the Rhine made it a crossroads of European rail geography, a role the city has maintained as cross-border high-speed services expanded in the late twentieth century.
