Really pleasant little read for anyone who likes railways, the Underground, transport, infrastructure, London, roundels, architecture or the use of well thought out and meaningful tile work!
Geoff’s passion for the topic, as seen in his YouTube videos, comes through in the writing and the pictures are well selected to illustrate some of the most interesting sights.
Well worth dipping into and, I imagine intentionally, a good size for taking for a journey on the Underground and seeing the sights for yourself.
