Since the beginning of this year, the offender has stolen copper cables at a number of locations on the Mernda and Hurstbridge lines.
On 14 March a male arrived at Bell Railway Station in a silver VW hatchback just after 1pm
The man enters the nearby substation, removes large spools of copper cabling and places them in the boot of the car before driving away.
