Sometimes you come across a lofty railway viaduct, marooned in the middle of a remote country landscape. Or a crumbling platform from some once-bustling junction buried under the buddleia. If you are lucky you might be able to follow some rusting tracks, or explore an old tunnel leading to...well, who knows where? Or the spectre of a train from a golden era of the past panting up the embankment? The Trains Now Departed is a journey into the soul of our railways, summoning up a magic which, although mired in time, is fortunately not lost forever.
