Toby the tram engine wants to help the farmer rescue his sheep who are trapped on the hillside covered by the snow. Toby’s driver phones the vet from the nearest signal box down to the station. The weather was getting so bad that Duck couldn’t clear the tracks. Then Toby had an idea. His old branch line ran up to where the hillside was. Sir Topham Hatt agreed, but told Toby to be very careful. Soon enough a blizzard was howling. Toby’s driver was worried. “I can do it, as long as these rails hold,” said Toby.
