Bluebell Railway
This pretty steam line in Sussex is a big hit with both adults and kids. It boards at Sheffield Park and ambles its way to East Grinstead, where you can get out and explore the old-fashioned station before your return. Each of the stations along the route evokes a different era in rail history, from the 1880s to the 1950s. Tickets cost from £23.50 for adults from Bluebell-railway.com.
