THIEVES scaled railway line poles between Wodonga and Chiltern to steal 39 kilometres of copper wire.
Detective Sen-Constable Justin Foots said the thieves would have had to climb the poles that run along the tracks.
Also, they would have had to use a roller machine to wind-in the wire they stole during the past three weeks.
“It’s a fairly involved process,” he said.
The wire formerly transmitted signals along the railway line and though the system is now disused, Sen-Constable Foots said the 39 kilometres of wire could fetch the thieves about $10,000.
He asked anyone who has seen anything suspicious along the line to contact police.
Officers were alerted to the theft after VicTrack reported the theft.
