Construction work between Cologne and Troisdorf
From Friday, 2 May at 10 p.m. until Monday, 19 May at 5 a.m., there will be construction-related restrictions on many train lines around Cologne Bonn Airport. Regional trains RB26 and RB27 will not serve the airport during this period for a period of two weeks. The S-Bahn line S19 will run between Cologne Central Station and Troisdorf, providing an alternative connection to the airport on this section of the route. Deutsche Bahn recommends that train passengers check www.zuginfo.nrw for information on replacement services and alternative travel options.
