This is a light overview of the history of the tube from someone who carries his anorak over his arm rather than wearing it.He looks into the early development of the tube, and some of the significant characters who made the Tube what it is today. But what makes this book something other than another Tube history is the way he weaves in his own journeys to the narrative.I enjoyed it, but couldn't give it five stars as it was missing that extra something.
