Jubilee Exhibition Railway: The Jubilee railway line is a former railway in Adelaide, South Australia.  It was built in 1887 from where the Adelaide station currently is to where the former Jubilee Exhibition Building was.  The line used an existing tunnel under King William Road which was built in 1854 to transport horses and cattle.  The tunnel is likely the origin of rumours about rail tunnels located under the city of Adelaide.  Much of the land where the line once ran has been constructed over to build parts of Adelaide University and the Adelaide Festival Centre.  There were no stations built.  No known evidence of the line remains today.
