Quite aside from the fact that the book has not been proof read and that the text seems to be copy-and-pasted from a different publication, the layout of the book is unintuative, and seems slightly random. Its only semi-saving grace is that it contains a handful of rare pictures.
If youre an historian, Brian Hardys tube and surface stock files 1935-1959, are far more in depth, better explained and better presented for what they want to achieve. Also 'Steam to Silver' and 'Tube trains under London' are for reccomendation. However if you have a serious interest in Tube Stock you've probably already got these books.
Likewise if you're a modeller the LT museums photo collection along with other written publications will provide ample detail.
I would have liked to have seen diagrams of car layouts, a contiguous and ordered table of main measurements (imperial and metric)/years/numbers of stock, and a list of formations used. None were contained within, aside from a few tables of stock main measurements, and even these were ordered in the book randomly.
Its simply not worth the money, and its possibly the only book I feel let down to have bought.
I expected far more from Glover; do not buy.
