London, England – July 4, 2017: this photo shows platforms, trains, and passengers at Paddington Station, one of the principal railway stations in London. The station was designed by Isambard Kingdom Brunel as the London terminus of the Great Western Railway (GWR), and it was opened in 1854. Brunel’s glass roof for the station’s vast train shed is a triumph of engineering, composed of a central span roof of over 100ft and two smaller side spans of around 70ft each. All the interconnecting ribs of the arched roof are made of wrought iron, and its overall design echoes the architecture of the Crystal Palace designed by Joseph Paxton to house the Great Exhibition in Hyde Park, London, in 1851.
