The national train operator, Deutsche Bahn, had already suspended rail trafficin North Rhine-Westphalia (NRW), neighbouring Rhineland-Palatinate state and Lower Saxony, when it announced a Germany-wide suspension of long-distance trains.

Many domestic flights have also been cancelled.

A national transport website, VID, reported 17 trucks blown over by the strong winds.
The Dutch Railways (NS) and operator ProRail said overhead power lines had been damaged by the wind, as well as some railway tracks.
An alert on the NS website said: "A hurricane-force storm is raging over our country and causing a lot of damage to the rail network and stations.
"NS and ProRail therefore have to stop the train service until further notice. Only Arriva trains in Groningen and Limburg can continue running."
