Poet Paterson: Train travel is a 'metaphor for life'

National poetry day is on Thursday and to mark the day, a collection of verse is being published celebrating rail travel.

The BBC's arts editor Will Gompertz went on a slow train from Marylebone Station in London, to Aylesbury in Buckinghamshire to find out what it is about train travel that gets poets' creative juices flowing.

The poet Don Paterson explained that train travel is "a metaphor for your life... the driver as god or your superego... and you can change train in the way that you can sometimes switch face."

First broadcast on BBC Radio 4's Today programme on Wednesday 2 October 2013.
