Getting to Cologne by train

Cologne’s main station is one of Europe’s most important railway hubs.

You can travel to Cologne quickly and comfortably from major cities in Germany and other European countries: Every day, more than 1,300 trains run between Cologne and destinations throughout Germany and abroad. Highlights of the service include the international high-speed trains that connect Cologne with London, Paris, Amsterdam and Brussels. With the high-speed rail service to Frankfurt, the Köln-Deutz railway station — the second terminal for high-speed ICE trains in Cologne — and the Cologne/Bonn Airport station, Cologne has further enhanced its vital role as a central hub for railway transport.
