Zweisimmen to Lausanne

Aboard the Golden Pass Express, Michael Portillo wends his way in style down steep mountainsides from Interlaken to the Swiss Riviera.

In Lausanne, he contends with a knife-wielding robotic arm at a renowned centre of science and technology. Michael is impressed by the robot’s skills in the kitchen and witnesses a groundbreaking prosthetic that allows amputees to feel heat and cold.

At a family-run dairy and Gruyere cheese producer, Michael marvels at the Gruyere wheels floating in their salt baths before tucking into a fondue.
