Perth trains could go driverless
Driverless trains are suggested as an option for Perth's rail system, Public Transport Authority tender documents reveal.
Other options are trains arriving every two minutes, more stations and the ability to "stack" trains end to end to help disperse crowds from the new football stadium.
The documents specifically seek private sector information on new technologies that would allow the PTA to "future-proof" its electronic signalling.
They indicate a new system would need to accommodate expansions and network changes, including more automation.
An example of automation suggested is driverless trains on special sidings, allowing trains to be turned around quicker because drivers would not have to walk from one end to the other.
PTA spokesman David Hynes said there were no immediate plans for driverless trains.
He said Perth's train operations were getting more complex and it was important that a new signalling system meet future investment decisions.
The concept of driverless trains has been explored globally for more than 40 years, led by London Underground planners.
The most extensive system is the Copenhagen Metro, where automatic trains close the doors and detect emergencies.
Other systems run automatically but have a staff member aboard to operate the doors and act in an emergency.
Other details in the PTA documents show new signalling would need to handle an airport link, stations at Aubin Grove, Karnup and South Perth, and extending the Joondalup, Armadale and Thornlie spur lines.
As well as much more frequent trains, the signals would have to provide for the efficient dispersal of crowds from the football stadium, which could include nine-car trains and to "stack" trains end to end so they can be filled quickly.
Shadow transport minister Ken Travers said the documents showed chaotic public transport planning with no indication of a timeframe or priorities.
