If it's a detailed London Transport history you want, or a techical guide to tube trains, then there are other books out there to explore. If however you're more into a lighter (although very informative) amount of text but enjoy gazing in wonder at a vast collection of visual memorabillia connected with London Transport (mostly the underground but loads on buses too) then I can't think of a more suitable book. There's a fair amount of text but it's swamped by the sheer amount of visuals, all with captions, which glide you through the book in nice little soundbytes. Programmes, posters, maps, illustrations, masses of colour throughout, this is a thoroughly well put together book, tracing the history from the dawning of the first transport system through to the modern day. Hard to put down, and definitely a "feel good" book, this pocket museum is worth every penny.
