A railhead and a quarry were established at Watson, about west of Ooldea, and Beadell's bush track from Watson to Emu became the main line of communications for the project. It ran north to the edge of the Nullarbor Plain, then over sand hills and the Leisler Range, a mallee, spinifex and quandong covered escarpment, rising to an altitude of . Range headquarters, known as The Village, and an airstrip with a runway were built near the peg. The track continued north over scrub-cover sand hills to the Teitkins Plain. There at a point that came to be known as Roadside, a control point was established for entry to the forward area where bombs were detonated.
