Heavy snowfall in northern France and Belgium has left tens of thousands of homes without power, and caused travel chaos for thousands of people.
Several thousand rail passengers remained stuck on trains late on Monday night.
In Lille, the regional airport was closed for several hours, and high speed trains experienced serious delays.
Trains into Paris from the north were disrupted after the weight of the snow brought down cables.
Some passengers were stranded for several hours. One train bringing people to work in the French capital arrived around the time they would have been heading home.
“I was on my way to work for 10.30 in Paris, but it’s now 6 o’clock in the evening : so I’ve arrived after a 12-hour journey,” said one young woman.
The amount of snow – around five centimetres – was small compared to elsewhere in Europe, but left the authorities struggling to restore power supplies.
