From Turner’s Rain, Steam and Speed (1844) through Monet’s Gare Saint-Lazare (1877), Edward Hopper’s Station (1908), Campbell Cooper’s Grand Central Station (1909), and on to the classic poster designs of the interwar London Underground (not least Harry Beck’s classic map design of 1932, imitated if not emulated in every subsequent railway and subway map the world over), railway trains and stations formed either theme or backdrop to four generations of modern pictorial art.
