Access

Head east from Rockhampton on the Rockhampton-Emu Park Road for about 20km past the railway crossing on the outskirts of town. The baseline will be on the southern side of the road (right) at a dirt road intersection (Cobb and Co Road). A dirt track runs adjacent to the baseline and provides vehicular access to each station.

Keys are needed to unlock the pillars and should be obtained from the local Department of Resources office in the town centre.

Design

Type: 7 station Schwendener. Stations are concrete pillars.

Datum RL: The datum plane is based on reduced level (RL) 0.0 metres. RLs for the stations are derived from station 0 – permanent survey mark (PSM) 69732.

Alignment: Base alignment is from station 0 to 6. Offsets are negative to the left and positive to the right of the line viewed from station 0.

Notes

• Pillar 1 was disturbed in 2009 due to an upgrade on the intersection of Rockhampton-Emu Park Road and Cobb and Co Road. Although the pillar may be stable again, take care when observing this station.
• Pillars are not easily visible from the road as they are on the other side of a tree line.
