Paris, the City of Light, is one of Europe's most iconic capitals and a cornerstone of the continental rail network. The city is served by seven major railway stations, each handling different routes: Gare du Nord (Eurostar to London, Thalys to Brussels and Amsterdam), Gare de l'Est (TGV Est to Strasbourg, Germany, Luxembourg), Gare de Lyon (TGV to Lyon, Marseille, Switzerland, Italy), Gare Montparnasse (TGV to Bordeaux, western France), Gare d'Austerlitz (services to central France), Gare Saint-Lazare (Normandy), and Gare de Bercy (overnight services).

Salzburg, Mozart's birthplace, is a baroque jewel set against a dramatic Alpine backdrop. Salzburg Hauptbahnhof connects to Munich (1.5 hours), Vienna (2.5 hours by Railjet), Innsbruck, and Zürich, making it a natural stop on trans-Alpine rail routes.

Vienna, the imperial capital of Austria, welcomes rail travelers at Wien Hauptbahnhof, a modern architectural landmark that opened in 2014 and serves as the city's central hub for international and domestic trains. From here, you're just a short metro or tram ride from the historic Innere Stadt, where the magnificent St. Stephen's Cathedral and the Hofburg Palace anchor a UNESCO World Heritage-listed old town.

Budapest, Hungary's stunning capital, straddles the Danube with hilly Buda on the west bank and flat, bustling Pest on the east. Budapest Keleti pályaudvar is the main international station, with direct Railjet services to Vienna (2.5 hours), connections to Prague, Berlin, Munich, Zagreb, and night trains to several European cities. Budapest Déli and Nyugati stations serve additional domestic and international routes.

Prague, the 'City of a Hundred Spires,' is one of Europe's most enchanting capitals, renowned for stunning Gothic, Baroque, and Art Nouveau architecture. Praha hlavní nádraží, the city's magnificent Art Nouveau main station, serves as a Central European rail hub with direct connections to Vienna (4 hours), Berlin (4.5 hours), Munich (6 hours), Budapest, Warsaw, and Dresden, making it an ideal base for exploring the region by train.

Berlin, Germany's capital, is a city shaped by history and reinvention. Berlin Hauptbahnhof, Europe's largest crossing station, opened in 2006 and serves as a major hub for ICE high-speed trains connecting to Hamburg, Munich, Frankfurt, Cologne, and beyond, as well as international services to Prague, Warsaw, Amsterdam, and Vienna. The station's dramatic glass-and-steel architecture sets the tone for a city that constantly reimagines itself.
