Great Asian Railway Journeys is a 20-part BBC travel and history documentary series produced by Boundless and presented by Michael Portillo, a former Conservative MP and Minister of State for Transport. Following the format of the highly successful Great British Railway Journeys and related series with Portillo as presenter, each episode features a railway journey in south-east Asia using Bradshaw's Through Routes to the Chief Cities, and Bathing, and Health Resorts of the World (1913) as a historical reference, in order to consider how the places visited have changed over the preceding century.
