|Basis: British Rail Class 08|
Iron 'Arry, along with his twin brother Iron Bert, is a Diesel engine that works down in the scrap yards and smelters sheds. As with most diesel engines, Iron 'Arry feels that Diesel engines are superior to steam engines and enjoys breaking them down when he gets the chance. Iron Bert loves breaking up old steam engines, and would really like to melt down Stepney and Oliver if given the chance.
- Because of his grim job of melting down engines, Iron 'Arry is sometimes referred to as the "Grim Messenger of Doom" by the other engines.
- Iron Bert has more stubble than his brother Iron 'Arry.
- Iron 'Arry and Iron Bert are based on British Rail Class 08 Diesel-Electric Shunters.
