German Railways has canceled all train services for the country's most populous state of North Rhine-Westphalia in as a winter storm moved to Germany from western Europe. The square in front of Cologne's cathedral was also partially cordoned off Thursday as a precaution in case of stones falling because of gusty winds. Children in many regions of Germany stayed at home because schools remained closed. The German news agency dpa reported only a few weather-related flight cancelations flights across Germany in Munich, Hamburg, Duesseldorf and Cologne in the morning. The storm is expected to reach western Germany around noon time and then make its way to the East during the afternoon and early evening.
