The world's favorite tank engine must defend the Island of Sodor against a new threat, one hell bent on elminating steam engines forever, under any cicumstances!

When the Skarloey Railway strikes a deal that will pull them out of their economic slump, the engines are assigned to help prepare it for the new owners. Duncan believes that the story about the Old Iron Bridge running above Cattle Creak is nothing more than an old tale made up to scare young engines, but he ends up getting the spook of his life.

A swap around of Lucina's mishaps, with Male Corrin, and Niles taking on the lead roles instead!

Lucina attempts to secure some food, but the residents of New Tendo City seem to have other ideas for what to do with her.

The year is 1923, and the end of the Great War in Europe has resulted in the British Parliament passing the Railway Act of 1923, turning hundreds of small British railways into five main companies. A small island in the Irish Sea named Sodor becomes a part of this as their networks are combined under the North Western Railway. A new era for Sodor has begun.
