New railway related books for 2017

For those who might be interested Hugh Longworth's new book is due for publication by Ian Allan circa mid-2017, namely:-
Pre-Nationalisation Coaching Stock British Railway Coaches Built 1923-47

If anyone knows of any new books that might be of interest, then perhaps they could post in this thread?

PS:
It's only today that I learnt that Ian Allan's bookshop near Manchester Piccadilly closed in June of this year!
