Brunel's Great Western Railway structures uncovered

Remnants of buildings built by the engineer Isambard Kingdom Brunel have been uncovered during work on London's £14.8bn Crossrail project.

The discovery, near Paddington, includes the foundations of an engine shed, a workshop and train-turntables, built as part of the Great Western Railway which saw steam trains first run through the area in 1838.

BBC London's transport correspondent Tom Edwards spoke to Jay Carver, from Crossrail, and Andy Savage from the Railway Heritage Trust.
