Gauteng Premier David Makhura wished the Metrorail commuters, most of whom were discharged from hospital, a speedy recovery.
“We are very concerned with the frequency of accidents on our trains,” Makhura said.
“These accidents should be avoided at all cost and we urge PRASA [Passenger Rail Agency of South Africa] to take all necessary precautions to ensure that passengers reach their destinations safely and alive.”
Makhura said 28 people were still hospitalised after the crash which saw one train collide into the back of a stationary train between the Booysens and Crown Mines stations.
Both trains were headed for Soweto.
In April, a Metrorail security guard was killed and 240 people injured when two trains collided at the Denver train station during the morning peak in Johannesburg.
