The Hawks' serious organised crime investigation team arrested five people for allegedly stealing railway lines in Morgenzon, Mpumalanga on Friday.
The people, aged 27 to 56, were arrested in Secunda.
Hawks spokesperson Captain Dineo Lucy Sekgotodi said on Sunday said that the people were caught while they were loading railway lines into various vehicles, including two trucks, a tractor and a bakkie.
The damage they allegedly caused was estimated to cost R1.5 million.
"The suspects were detained and charged, pending their first court appearance on Tuesday," Sekgotodi added.
They are expected to appear in court for damage to infrastructure, theft and the possession of suspected stolen property.
