Overview:Armed with his 1913 Bradshaw’s Guide, Michael Portillo boards the Unification Railway for a thousand-mile journey from Ho Chi Minh City in the south to the northern capital, Hanoi, and finishing in the beautiful emerald seas of Halong Bay. Michael’s Bradshaw’s unlocks for him the traumatic 20th-century history of today’s Socialist Republic of Vietnam, a former French colony. On this leg, Michael braves the streets of Ho Chi Minh City on a motorbike, one of 8.5 million people to do so daily. He attempts the national sport, da cau, and samples the French-Vietnamese fusion food banh mi.
