On Sir Topham Hatt's railway, the winter season is a very special time of the year and all the engines work extra hard to make the holidays special. But it's not always easy. Find out what could happen if the villages on the Island of Sodor don't get their Yule tree in time for the winter celebration. See if Percy's snow-covered face tricks James and the rest of the engines into thinking they have seen the very scary Jack Frost. Watch if Duck is able to get to Farmer McColl's lambs in time to save them from being trapped in the snow. Join Thomas and his friends for some snowy adventures as they work to keep this winter season on track. -
