But we can confirm that it’s two on site. The bodies have just been recovered. One person who was seriously injured in hospital, we are told he passed on." Vadi said that 620 people had been injured, 11 severely and 61 moderately. Train services between Mabopane and Pretoria would remain suspended until further notice, he added. Lines closed "The site has not been handed over by the Emergency Management Services to the railway authorities and the railway safety regulator. I suppose they want to do the forensics of the deceased," he said. Vadi said that, as soon as the paramedics were done with their work, they would start clearing the railway. "There is very serious damage to the train... and I would guess that at least two to three days of work might be involved here in terms of clearing the site," he said. Prasa had arranged for 18 buses to transport commuters until the railway was reopened, Vadi said. Cause undeterminedMofokeng said the cause of the collision was still undetermined."These trains were both travelling on the same line towards Pretoria from Mabopane. A board of inquiry will be instituted to determine the root cause of the accident," she said.

"I think the issue of theft and vandalism of railway infrastructure is a matter of serious concern." Transport Minister Blade Nzimande is set to visit the station on Tuesday evening and would issue a broader statement, Vadi said.
