Travel: Chris Tarrant: Extreme Railway Journeys, 9pm, Channel 5

He gets about, that Chris Tarrant, doesn’t he? Tonight, the roving host (left) sets out on a mission to cross three former Soviet republics entirely by rail in just a single week, travelling through Estonia, Latvia and Lithuania and uncovering amazing stories and dark secrets from the region’s past. His stop-off points in Estonia include Narva and Tallinn before he heads to the Russian border on a revolutionary new line. We are jealous of you, Chris.
