Police are investigating after a fire damaged eight old wooden train carriages in a Woodstock shunting yard late on Sunday.
Firefighters extinguished the fire at 1.30am the next morning, according to Fire and Rescue Service spokesman Jermaine Carelse.
“One firefighter sustained a minor injury and was taken to hospital,” said Mr Carelse.
Metrorail spokeswoman Riana Scott said the old, disused wooden carriages belonged to Transnet and were not Metrorail rolling stock.
Woodstock police spokesman Warrant Officer Hilton Malila said police were investigating a case of malicious damage to property, but no arrests had been made.
Transnet spokesman Molatwane Likhethe said the fire had damaged eight of the “heritage” coaches.
“Transnet is investigating the cause of the fire,” he said.
