Bertie the Snow Bus is a 1994 annual story.
Returning to the bus station one winter’s day, Bertie gets stuck in the snow. His driver leaves him to go for help and the snow soon mounds up around the bus, covering him like a blanket. After a while, Terence is able to clear the snow away and tow Bertie back to where the snow is less deep. Bertie is very glad to get home to his nice warm bus station at Wellsworth.
