The Burrawon Branch is an Australian HO scale model railway. Burrawon is a fictitional rural branchline terminus based on New South Wales Government Railways practice in the late 1970s/early 1980's era. The layout consists of several dioramas linked by short sections of running line. Burrawon is on one level and linked to its mainline junction - Tarawangan - by a 5 loop helix. One Mile quarry sits atop the helix.
