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 much greener and livelier than ever before.
In the eighth series, many of the trees between the railway lines were removed, and only three lines ran through the forest. Fences were also placed beside the railway line.
