I bought a copy of the book at Model Rail Scotland a few weeks ago and i'm very impressed. I hadn't seen the photo of the engine shed from the other side before and the quality of the photos and drawings is very high. Looking forward to book 2 now.
My only criticism would be the drawing scales used. While most of the locomotives and wagons are 1/24th, other drawings are 1/12, 1/16, 1/19.05, 1/32, 7mm/ft and are sometimes mixed within sections of the book - for example the bogie stock is all drawn to 1/32 (presumably to fit the whole drawing on one page) but the separate bogie drawings are 1/24. Sticking with one or two scales would have been better.
Still a highly recommended book.
