Despite the end of rail freight on the Eyre Peninsula, railway crossing signs and the 80 kilometres an hour zone on the Flinders Highway will remain in place according to the Department of Planning, Transport and Infrastructure (DPTI).
The decision by Viterra in February to cease its grain haulage agreement with Genesee and Wyoming and transition to road-based transport on May 31 will not affect signage or speed limits near railway crossings as the railway will still be used occasionally.
A department spokesperson said the railway crossing stop and give-way signs in Port Lincoln and Cummins would remain in place and continue to be enforced.
The spokesperson said the 80km/h speed limit on the Flinders Highway near Coomunga would also need to remain as the rail line would still be used.
"Genesee and Wyoming Australia has advised that while grain trains have ceased, the line is still active, with the potential for occasional locomotive movements.
"Road/rail inspection vehicles will still also be required to meet ongoing commitments to the state government in relation to the maintenance of the track and civil infrastructure.
"DPTI will nevertheless review these locations as part of the planning of the proposed road improvements on the peninsula."
Instances of people removing railway crossing signs in the Lower Eyre Peninsula Council's district area have already been reported to the council.
The council posted a statement to its Facebook page that the line would see occasional light engine movements, track inspections and vegetation operations as well as the relocation of locomotives between Port Lincoln and Thevenard.
The council urged the community to stay safe and obey the signs at all railway crossings and warned the removal of signs could endanger lives.
Any missing railway crossing signs should be reported to the relevant council.
