Calling All Engines

Calling All Engines is about a new airport being built on the Island Of Sodor, and its construction leads to the rivalry between the steam engines and diesel engines reaching boiling point. However, a storm slows work down, and soon the steam engines and diesels have no choice but to work together to complete the airport. Of course, this is not an easy task, and the engines must work hard to fix the many damages caused by the storm, especially at the airport construction site, where the most damage was made.

There is speculation among fans as to whether this film can be considered canonical with the TV series. It was released between seasons 8 and 9 of the TV Series, but few of the events of the film have had any bearing on the TV series. Tidmouth Sheds are rebuilt in this film, to having seven spaces (where there were six previously). The "rebuilt" Tidmouth Sheds were seen in the TV series from Season 9 onwards. The Sodor Airport, constructed in this episode later appeared in Season 10. However, the so-called "return" of characters such as Daisy and Derek does not appear to have had any effect on the TV series, and nor did the treaty between the steam and diesel engines until Season 10.
