Bought my 30th and last Platform 5 combined volume today, only really got it and the last couple out of slight curiousity over the modern railway which has now almost evaporated. Quite a difference from the first edition I bought in 1985!
I suppose they make a nice set on the bookshelf - every edition since it was first published 30 years ago. The first one has banger blue class 25's on the cover!
