A violent fight on the Monorail line breaks out after a train carrying about two dozen passengers breaks down on the tracks early one morning. The police move in, arrest the fighters and rescue the victims. It's a typical riot on the train, or is it?

The riot, is actually a crisis training exercise that transit company Prasarana has been running with government agencies like the fire department and the police. It's one of the many situations that they practice just in case the real thing happens.
