Gawler to Angaston - Book of the Line - c1909
At the time of construction of a line, or the extension of a line, a book of drawings would be produced. The book would contain drawings of standard infrastructure to be used in the construction. These books in part were used to obtain the funding for the project and were also used by contractors for providing quotes. This book is a PDF file that contains scans of 55 full size drawings produced in 1909 with a page size slightly smaller than a metric A0 sheet.
