She explains that St. Stevenson comes to reward good engines and rolling stock, and punish the naughty ones. He announces his arrival with the ringing of bells. The trucks hear this and when Toby arrives, ringing his bell, they get a fright promise to be good, for at least 24 hours.

Toby meets Thomas and Percy, who form a train to help take down snowdrifts. They remove the snowdrift at Henry's Tunnel and Daisy joins to get to Knapford station.
