Transport minister Blade Nzimande has blamed the recent burning of two Metrorail trains at Cape Town Station on a relentless force determined to reverse gains that the ANC government has made. News24 previously reported that four train carriages were destroyed on platform four and another four carriages on platform 14 at the station on Sunday in a suspected arson attack. Metrorail has since confirmed that 12 carriages have been gutted by the fire.

Surely after the first incident you put the most stringent measures in place to ensure this doesn’t happen again? How is it that criminals can so brazenly burn our trains time and again and get away with it?"
