John Sergeant on Tracks of Empire

John Sergeant embarks on a unique 3,000 mile journey through the history of the greatest legacy the British left to India - its rail network. The biggest in Asia, it runs on 40,000 miles of track and reaches every corner of the subcontinent. Proposed in 1853 by Governor General Lord Dalhousie, it would become the biggest engineering project of its time and instrumental in every chapter of India's history.
