The temperature dropped from unpleasant static heat to the level of cold that threatens frostbite within a remarkably short time. The train listed to one side. Not very much, but enough to cause pain in one of my shoulders. I was sitting on the left in the carriage, and was the only person in a wheelchair on the entire train. A wall of dirty white was pressing against the window on my side. It struck me that the enormous quantities of snow had saved us; without them the train would have jack-knifed.

The cold was debilitating. I had taken off my sweater back in Hønefoss. Now I was sitting here in a thin T-shirt, clutching a baby to my chest as I realized it was snowing into the carriage. The bare skin on my arms was already so cold that the whirling, blue-white flakes lay there for a chilly second before melting. The windows had caved in all along the right-hand side of the carriage.

The wind must have increased in strength during the few minutes that had passed since we stopped to allow people to get on and off the train at Finse station. Only two passengers had disembarked. I had noticed how they leaned forward against the wind as they struggled across the platform towards the entrance to the hotel, but it didn’t seem any worse than normal bad weather up in the high mountains. Sitting here now, with my sweater tightly wrapped around the baby and with no chance of being able to reach for my jacket, I was afraid that the wind was so strong and the snow so cold that we would freeze to death within a very short time. I curled my body over the tiny baby as best I could. With hindsight I can’t actually say how long I sat like that, without any contact with anyone, without saying anything, with the shouts of the other passengers like disconnected fragments in the dense howling of the storm. Perhaps it was ten minutes. It might have been only a few seconds.

‘Sara!’

A woman was glaring furiously at me and the child, which was entirely pink, from its cardigan to its tiny little socks. The small, clenched fists that I was trying to cover with my own hands, along with the furious, yelling face, had a pale pink tinge.
