Tube ponderings with Barry Heck
Our resident tube fancier dishes out daily thoughts on the London Underground.

If you've ever stepped out of the tube station at Wood Green, you might have wondered 'Where is the wood?' and 'Where is the green?'. Look, instead, within the station. The old ticket office has been turned into a 'tiny park' by horticultural interventionists The Edible Bus Stop. The unusual planter is a sequel to an experiment a couple of years back at St James's Park. Follow Barry on Twitter @HeckTube.
Good cause of the day
Head to Waterstones Piccadilly tonight to hear from journalist and author Holly Bourne about romance, feminism, #MeToo, and crying in public. The event raises money for Women's Aid. Find out more and book tickets.
