"Halloween" is a Halloween-themed episode of the British animated TV series Thomas and Friends, based on the Railway Series books by Rev. W. Awdry. The episode first aired in the United Kingdom on the ITV network on October 10, 2004.
Thomas and Emily are sent to do an errand at the smelters on Halloween. But Arry and Bert scare them knowing they are afraid. When a tarpaulin falls onto Emily, Thomas, Arry and Bert get frightened away with Emily following them thinking a ghost got her. The chase ends back at Tidmouth Sheds where the tarp flies off Emily after going under a signal bridge. After Sir Topham Hatt (the railway's controller) comes to see what the noise is about, Bert admits about the trouble he and Arry caused and they are sent back to the smelters to do Thomas and Emily's work.
