In 21st-century Scotland, travel and transport is changing. Scotland's trains, planes and ferries are busier than ever. New services like the Borders Railway and a seaplane to Skye are connecting far-flung communities. In Aberdeen, hydrogen-powered buses are revolutionising public transport and cutting carbon emissions. In Dundee, electric taxis are making travel cheaper and cleaner. Meanwhile, older systems like the unique Glasgow subway are being updated for the modern world. This documentary tells the story of Scotland on the move through a diverse cast of characters including a train driver, a ferry captain, the nightshift engineers on the subway, a pioneering pilot, and one of the original architects of Glasgow's groundbreaking urban motorway system.
