Overview: We celebrate one of Britain's most ingenious and prolific engineers - Isambard Kingdom Brunel. A perfectionist intent on managing every last detail, Brunel relished the task of building a high-speed and comfortable passenger line linking Bristol to London. As much a work of art as a transport network, his constructions included Paddington station, Clifton Suspension Bridge and Box Tunnel - at the time, the longest railway tunnel the world had ever seen.
