Hundreds of commuters were left stranded yesterday afternoon after trains operating in the western Johannesburg areas were nowhere to be seen.
Train stations such as Langlaagte, Crisis, Longdale and New Canada were packed with confused commuters who had been waiting for trains between 4pm and 7pm.

The crisis is alleged to have been caused by an electricity problem and comes only less than a month after commuters from all over Gauteng were left stranded after Metrorail's Cetral Train Control centre was completely destroyed due to thunderstorms.

Sowetan could not get hold of Metrorail spokesman Thokozani Zitha for an explanation.
