The Guinness Railway Book

I was looking for a book on Guinness' own internal railway. The book, however, is composed in the style of a "Guinness World Record", encompassing railway feats around the world. It IS an interesting read! However, I didn't ask the seller ahead of time about what the book was about. It's a fine "bathroom reader" book that's interesting no matter what page you open up. It's simply not about Guinness' own railway. (Not sure it's even mentioned in the book but I'm not all the way through it.)
