Several northern European countries were restoring transport and electricity services on Friday after a powerful storm that killed at least three people started to abate, dpa reported. Danish trains, shut down indefinitely on Thursday, were back in operation on a reduced schedule. Copenhagen airport was reopened, though only a small number of flights was able to depart. Denmark was working to restore electricity to 30,000 shops and homes affected by the storm. Two trains derailed on the Danish island of Funen, leaving one of the conductors with minor injuries. Three people were injured in a separate incident which saw a bus blown off a road in the south of the country. In Germany, which was affected to a lesser degree, Lufthansa cancelled 70 flights on Friday - primarily domestic routes and those flying across northern Germany. Fallen trees blocked railway lines in the northern state of Schleswig-Holstein and high tides flooded a low-lying market square in the port city of Hamburg. Police said on Friday that the worst was over. The three people killed by the storm on Thursday included victims in Scotland, England and Denmark. Britain was the first to be hit by the storm, which blew in from the Atlantic, with a truck driver killed on Thursday when his vehicle toppled over on to several other cars on a road near Edinburgh. A falling tree killed a man near Nottingham, England. And Danish police on Thursday evening confirmed the death of a 72-year-old woman whose vehicle was tipped over by strong winds.
