Peak hour passengers have been forced to evacuate a train after an electrical fault caused an explosion on the train's roof just outside Melbourne's Flinders St station on Thursday morning.
Footage of the incident shows a large explosion close to the overhead wires with the roof of the carriage appearing to be on fire.
Commuters reportedly rushed to the back of the Metro train when its power line connectors exploded. The top of the first carriage saw the impact of the spark, with passengers having to move to the third carriage to move away from it.
The train was stopped between Batman Ave and Flinders Street Station, on the Sandringham line.
However, the Melbourne Fire Brigade has denied there was a fire on the train.
