Re: GCLR2 Totally new angle for viewing the extension.

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.
