Cologne/Düsseldorf (dpa/lnw) – Due to a fire brigade operation along the route, there were temporary problems in rail traffic between the main stations in Cologne and Düsseldorf on Monday. Due to a route closure due to the operation near Langenfeld, regional, long-distance and S-Bahn traffic were affected by diversions, delays and partial failures in the afternoon, said a spokeswoman for the railway. Although the blockage was lifted after a good hour and a half, shortly after 5 p.m., until everything went back to schedule, it said it would take a while.
