By Jorge Joaquim A train transporting iron ore from South Africa to Mozambique collided with another train going in the opposite direction, on the South African side of the border between the two countries on Tuesday evening. Both trains were operated by Mozambique’s state ports and rail company CFM, though the train going to Mozambique was owned by South Africa’s Transnet. Transnet Freight Rail (TFR) told News24 that there were no injuries, but that traffic had been halted on the line between Komatipoort in Mpumalanga and Ressano Garcia in Mozambique. "Investigations are under way to determine the cause of the accident," it said. This accident comes a week after a Transnet train carrying export coal to Richards Bay derailed, affecting a key line. Some 87 wagons derailed in that accident, which also damaged a large portion of the track and prompted Transnet to declare its sixth force majeure in just 18 months.
