Yup, in stock at my emporium (unlike a certain Warship book - grr).
Very interesting, apart from the great shot that Rippers mention above there are a lot of good views, many in colour. Also drawings, a bit "weight diagram-ish but still useable and some really good colour shots of the interior of the AC cars type. I also liked the several views of the tiny halts put in on several lines when these vehicles were introduced. This is one title that I think I will addd to my own library.
Pricewise, I agree that it's a move upwards from previous price points for this style of book, but it's not as much as the new Bob Essery book from Ian Allan at £19.99 and in any event book prices do need to go up a bit if publishers are going to keep producing them.
For the cover price of this book you can alternatively buy about 2 and a half gallons of diesel or 12 odd loaves of bread, OK - where did I put that butter knife...
