Chris Tarrant: Extreme Railway Journeys: Balkans

Chris Tarrant explores five countries that were part of Yugoslavia, which had an extensive state-run railway network before its break-up in the 1990s and the Balkan Wars of Independence that followed. From Slovenia, Chris heads east along an old Austro-Hungarian railway that was once used by the Orient Express, pays a visit to a very unusual railway-related battlefield in Bosnia and rides on one of the world's great mountain railways on his way to the Serbian capital Belgrade before finishing his journey in Montenegro
