Metrorail has launched the Masibambisane anti-crime campaign.
It aims to fight train surfing, which has killed many young people in the last three years, and other criminal acts involving train commuters.

Over the next three months Metrorail would hold roadshows and media campaigns throughout the region.
Metrorail runs 2,2 million passenger trips each weekday nationally.
