Mr Nalder was responding to claims by Opposition Transport spokesman Ken Travers that the State Government had produced an animation of the proposed line before the 2013 election, but had now dropped the project.
‘The State Government committed to planning for this project in 2012,’ Mr Nalder said.
‘The extension of the Thornlie line to link with the Mandurah line remains a longer-term priority.
‘In the meantime, the Public Transport Authority is progressing planning works around the project as the Government considers it essential to plan and preserve options for future works.’
Mr Travers claimed the State Government had spent $1.5 million on consultants in planning for the project.
‘The Government had an animation of the proposed route produced in preparation for an announcement,’ he said. ‘These revelations will be extremely disappointing to the people in the southern suburbs.’
Gosnells MLA Chris Tallentire said extending the Thornlie railway line was ‘vital’ for the southern suburbs.
‘There are massive congestion problems on the roads in the south-eastern areas and this can only be alleviated by transport links,’ he said.
‘It is a fast-growing area and the problems are only going to get worse.’
