I reckon the original railmap is from either 1958 or 1959, as there is no railway showing between Grange and Henley Beach, which closed in '57.
Also if ever you have the opportunity, take a look at the Tramways Map of Adelaide prior to '57. I don't imagine that in the next 50 years the tram network yet to come will be as extensive as it became in the first half of the last century.
