Forth Bridge - S4.E1

Tim heads north of the border to scale a Scottish railway icon – the Forth Bridge, without doubt one of the engineering wonders of the world. Tim conquers his fear of heights to learn its story from its foundations, deep under the Firth of Forth, to its summit 110 metres above the water. At Goathland, North Yorkshire, is a railway station where movie magic was made, possibly better known today as Hogsmeade from its starring role in the Harry Potter films.
