This is probably an impossible question as I don't have much to go on, but I'd love to know what the book was that I spent hours pouring over with my grandfather when I was a kid. Sadly I think it was thrown away at some point. It was a fairly slim hardback book full of realistic colour drawings of railway scenes from around the world. The scenery was just as nicely drawn as the trains themselves. Each double page spread was a different drawing and country (I recall Britain, Switzerland and Japan were featured amongst others, maybe 15 in total) and a short bit of blurb. I think they were predominantly diesel locos but I think there might have also been a couple of electrics. It was my father's before me so it would have probably been purchased some point in the 70s. Most likely in the UK, but it could have been Australia if it was the early part of the 70s. I would have been quite young when I enjoyed it, probably around 7 or 8, but mostly used it to play a game of guessing the various nationalities. I think the blurb was a little too technical for me to really properly understand so would have been aimed at someone a bit older. Any guesses would be really appreciated as I have some very fond memories with my grandfather associated with the book and I'd love to be able to hunt a copy down if there are still any in existence.
