“Hello, J-J-J-J-James?"
"Scary Jack Frost!”
―Percy and James

Jack Frost is the sixteenth episode of the sixth series.


It is an icy winter day on Sodor, The Fat Controller's engines are working very hard. They are not bothered by the cold weather because of their warm fireboxes. Later in the evening, The Fat Controller arrives at Tidmouth Sheds and announces to his engines that a snowstorm is coming to the island, so he has Percy and James collect coal for the stations to keep them warm, and Thomas mischievously warns them about Jack Frost but James is dismissive, while Percy is uncertain about Thomas' warning. 

When the skies darken, Percy begins his coal deliveries and becomes nervous while trying to understand that Jack Frost isn't scary. At the same time, James is puffing along his route, scoffing over Percy's uncertainty of jack frost. When Percy makes his final delivery at Lowery Suddery station to find the stationmaster waiting for him; he needs twice as more coal so Percy gives them the coal from his bunker. Percy's crew then park him into a nearby siding with a lantern as a night light. Percy is worried Jack Frost would find him, but his driver reassures him that Jack Frost isn't scary and that Elizabeth will deliver him a new supply of coal. After his crew head home for bedtime, a snowstorm comes in late at night, where Percy is soon covered in snow and icicles. He is extremely frozen that could barely speak. Meanwhile, James finishes his deliveries and heads back home to Tidmouth Sheds, still scoffing over Percy's remark. On the way, he sees unusual and scary shaped shadows in the distance through the heavy fog, but when he finds Percy frozen, he mistakes him for "Scary Jack Frost" and runs home terrified.

The next morning, Elizabeth brings Percy a new supply of coal, and she is surprised to see Percy completely frozen. His fire soon starts, and the snow and icicles melt off, and decides that Jack Frost is actually not scary at all. When Percy returns to the sheds, James is bragging to the others that he saw Jack Frost. Percy adds that James was scared of him too, but the red engine is still able to make good humour of the situation.




  • Edited stock footage from Percy's Promise is used. This is denoted by the fact that Percy's floor appears to be wet and floorboards are used to start up the fire instead of coal.
  • This was the only sixth series episode that was not released on VHS and the first to only be released in a Complete Series DVD in the UK. However, it was featured on the Australian VHS, Twin Trouble.
  • This episode was broadcast the same day The Fogman and Other Stories was released.
  • This episode marks the last appearance of Lower Suddery to date, non-counting being mentioned in All in Vain.
  • Percy's original perspex model was used when he was at the Sheds.


  • The shot of Percy when Elizabeth says, "It looks like Jack Frost really got you then," is mirrored as Percy's lamp and brake pipe are on the wrong side of his running board and his number "6" is flipped.
  • When James arrives at Tidmouth Sheds, Duck's eyes are wonky.


Percy: [shivering; with icicles accumulating all over him] O-oh, b-b-b-bother!

Percy: [frozen] Hello, J-J-J-J-James!

Elizabeth: [sees the frozen Percy] Oh, my dear! It looks like Jack Frost really got you!
