Spencer is a top of the range classy steam engine with a tender - an A4 Pacific. He is metallic silver with blue details. Privately owned by the Duke and Duchess of Boxford, Spencer is a bit of a snob with a posh accent, and like the royal train, he pulls Pullman coaches, a private dining car etc. Faster and more powerful than even Gordon. Requires 1 x AA battery. For ages 3 years and over.
