Airport

Cologne's international airport is Cologne/Bonn Airport (CGN). It is also called Konrad Adenauer Airport after Germany's first post-war Chancellor Konrad Adenauer, who was born in the city and was mayor of Cologne from 1917 until 1933. The airport is shared with the neighbouring city of Bonn. Cologne is headquarter to the European Aviation Safety Agency (EASA).

Railway

Cologne has a railway service with Deutsche Bahn Intercity and ICE-trains stopping at Cologne Central Station, Deutz and Bonn Airport. ICE and Thalyshigh-speed trains link Cologne with cities in neighboring countries such as Amsterdam, Brussels and Paris. 

The Cologne city railway  (KVB) referred to as U-Bahn serves Cologne and a number of neighboring cities. Nearby Bonn is linked by both the city railway and Deutsche Bahn trains, and occasional recreational boats on the Rhine. Düsseldorf is also linked by S-Bahn trains which are operated by Deutsche Bahn.

There are also frequent buses covering most of the city and surrounding suburbs, and Eurolines coaches to London via Brussels.

Bicycles

Like most German cities, Cologne has a traffic layout designed to be bicycle-friendly. There is an remarkable cycle network, featuring cycle lanes linked by cycle priority crossings. In some of the narrow one-way central streets, cyclists are explicitly allowed to cycle both ways.
