During Halloween, the engines love to hear tales about ghostly and scary steam engines. The Halloween Engine was briefly seen in the Smelter's Yard. Thomas, 'Arry and Bert had once mistaken Emily for the Halloween Engine, after a white tarpaulin had fallen on her.
The Halloween Engine is painted rusty red and brown, resembling the colour of scrap.
- Thomas' Hallowe'en (mentioned)
- The Halloween Engine's model was recycled from one of Gordon's scrap models and one of Henry's six tenders from Tender Engines, with an added red tail lamp, along with Murdoch's cylinders.
