Train
The Mathematical Institute can easily be reached on foot from the train station Köln Süd which is one stop from Cologne's central train station Köln Hbf.
Plane
The closest airports are Cologne Bonn Airport (CGN) and Düsseldorf Airport (DUS), but there are also direct trains between Cologne and Germany's largest airport Frankfurt Airport (FRA).
Information on the strike
The trams are not running on Wednesday. Buses and regional trains are running as planned but might be delayed. From Köln Hbf we suggest to take one of the regional trains RB48, RE22, RE5, RB24, RB26 or RE12, to Köln Süd and then walk to the Mathematical Institute (10 min. walk).
The Mathematical Institute is located in the main campus of the University of Cologne.
