This is the title of an interesting new book which has been brought to my attention.
It has been produced by the M&GN Joint Railway Society, and was written by Dennis Greeno and Richard Adderson. As its name implies it covers the whole county, so a lot of the material relates to the GE lines. It is essentially a book of photographs accompanied by detailed captions - the pictures are mainly black and white, of course, but a few are in colour. We do not supply the book, but it can be obtained from the M&GN Society's eBay shop. You can read more details at https://www.ebay.co.uk/itm/Norfolks-Railways-1927-1966-/302483635352 .
