I believe last weekend's shutdown was to install one of the new crossovers, the other one I think was done late last year.
Im currently working on the project at Karnup.
In early October 2013 we will be commissioning new signals, 8 point machines for the crossovers at the north and south end, remote controlled electric isolators for the overhead and a CCTV system.
Initially there were plans for a Temporary platform, however this has been canned.
PTA will have the ability to terminate a train at Karnup and send it back to Perth should there be an incident such as a bush fire.
Our drawings show a proposed platform length of 150 Metres sited just north of Paganoni Road bridge.
The word is that a railway station at Karnup is 4 years away and i suspect that Aubin Grove will happen first.
