World’s Most Scenic Railway Journeys
Channel 5, 8pm
This diverting series, smoothed along as ever by the mellifluous tones of narrator Bill Nighy, is back for a sixth series. The first rail-riding odyssey begins with a trip from the west to east coast of Scotland, now largely patronised by tourists, beginning at the Kyle of Lochalsh and ending in Aberdeen, via the whisky heartland of Speyside.
