Hi Ikho
You could do worse than read this book, you should be able to find it on amazon

IT tells you all about trainspotting from the eyes of an enthusiast in the 1950s and 1960s, and is full of anecdotes that will really get you inside the mind of a "Spotter" in those days, which were really the heyday of the hobby.
