A power fault on a Melbourne Metro train triggers explosions inside a carriage, leaving passengers trapped and scrambling for help, multiple outlets report. Video and descriptions from the incident show the carriage being rocked by what are described as multiple blasts shortly after the fault occurs. Passengers are said to become unable to move freely as the train remains affected inside the affected service area.

All reports attribute the event to an overhead power fault, rather than a collision or other cause, and describe the incident as occurring while the train is in operation on the Metro network. The accounts differ mainly in emphasis—some focus on passengers being trapped, while others highlight the explosions captured on footage—but they are consistent on the core sequence: an overhead power fault occurs, explosions break out in the carriage, and passengers are left stranded or unable to exit promptly.

Emergency responses are implied as passengers seek assistance, though the provided summaries do not specify the exact timing of evacuation or the number of injuries.
