Johannesburg – There is no record of Prasa's chief engineer, who designed Prasa's controversial locomotives, having studied at Wits University, as he has claimed, Netwerk24 reported on Wednesday.Dr Daniel Mtimkulu allegedly studied engineering science at the University of the Witwatersrand, before going to study in Germany and get his doctorate. Wits’ registration office could, however, find no record of Mtimkulu having been a student.He is also not registered with the profession's statutory body, the Engineering Council of South Africa (Ecsa), which is a requirement for people working for government entities.He is head of engineering services at the Passenger Rail Agency of South Africa (Prasa). In 2006, Ecsa rejected Mtimkulu’s application to register with it as he did not hand in training and project reports. These were needed as proof that he received training from a registered engineer.Ecsa told Beeld that at the time of his application, Mtimkulu only had a BTech qualification and a national diploma.Mtimkulu was introduced at a press conference on Monday as the designer of the Afro 4000 locomotives.According to Rapport, he bought the locomotives, worth R600m, despite warnings that they were not suited for local conditions. They were built in Spain and imported from December 2014, but were apparently too high.At Monday’s press conference, Prasa CEO Lucky Montana, flanked by Mtimkulu, dismissed Rapport’s article and said there was nothing wrong with the locomotives.Neither Prasa spokesperson Moffet Mofokeng, nor Mtimkulu, could be reached for comment.
