Henry's Forest is a forest on the Main Line, located between Crovan's Gate and Vicarstown. It is nicknamed after Henry, who frequently visits the forest. Once, a storm tore down roughly half the trees, leaving much of the underlying hills bare. This created a bleak landscape, depressing engines and people alike. Sir Topham Hatt purchased replacement trees from a plant nursery, and now the forest is greener and livelier than ever before.
