History of Britain's Railway

I don't like WHSmith much, I refuse to call it a bookshop even. I think it is pretty much a glorified stationary shop, with some books on sales here and there. That said, sometimes, just sometimes, you find something worth your attention. So last time we went to one, I saw this History of Britain's Railway. I did not buy it, even though it was "only" £10. I already have a big pile of TBR books. However, I will keep this book in mind for future birthday present lists.
