Britain's railways have been a vital part of national life for nearly 200 years. Transforming lives and landscapes, they have left their mark on everything from timekeeping to tourism. From the classical grandeur of Newcastle station to the ceaseless traffic of Clapham Junction, from the mysteries of Brunel's atmospheric railway to the lost routines of the great marshalling yards, Simon Bradley explores the evolution of trains, and the changing experiences of passengers and workers. Chaired by Matthew Engel.
