Richard,
In the mass concrete track, how is the gauge established in the construction process? In the Jetty Rd track it was through tie-rods between the rails whereas in Melbourne it was the use of the half sleepers. In photo 4 the track seems to be constrained by rail bolts screwed into the wooden sleepers.
