Rusty the Diesel Engine worked at the Quarry on the Island of Sodor. Rusty's best friends were Rheneas and Skarloey. Their line ran through forests and over hills. They loved it very much. But it was old and messy. Rusy often left the Quarry to help his friends keep their line clear. Sometimes he worked so hard he forgot all about the Quarry! This wonderful Thomas The Tank Engine book is all about Rusty and how he saves the day!
