A picture of a snow-encrusted toilet on a Polish train has become an internet hit, highlighting the somewhat shabby nature of rolling stock on Polish railways. Newspapers dubbed it the “throne of the snow queen”. It was snapped by a passenger on a train to Warsaw travelling from the north-west city of Szczecin. The railway company said the unusual white-out was caused by an unsealed window. Email your photos of fog, frost and winter weather in Britain to mypic@telegraph.co.uk
