Michael Portillo uses George Bradshaw's Continental Railway Guide to explore Switzerland, whose remarkable railways helped make it a favourite with Edwardian tourists. He begins in the truly international city of Basel and travels east to visit industrial Zurich. He then heads for the glorious Alps and learns how astonishing engineering feats conquered the most challenging peaks, before taking in the striking beauty of Lake Lucerne. Michael's journey ends with a spectacular ascent by train to Europe's highest station, perched atop Switzerland's dramatic Jungfraujoch.
