The man who can taste the Tube map

20 November 2013 Last updated at 01:37 GMT

Most London commuters have a love/hate relationship with the Underground depending on their experience of delays. But for one man, travelling on the Tube has a very particular effect.

Since childhood, James Wannerton from Dollis Hill in north London has had a condition called synaesthesia, which links senses normally experienced separately.

It means that when he reads the names of London Underground stations, each one conjures up a particular, strong taste - from sausage and eggs at Tottenham Court Road to putrid meat at Kilburn.

He has now created a new version of the Underground map which he hopes will help people understand the condition.
