Two people were killed when a train carrying 153 passengers between Sydney and Melbourne derailed.
The crash occurred near Wallan, a town north of Melbourne on Thursday night.
Police said the male driver 54, and his female co-pilot, 49, died in the crash while 11 others had minor injuries.
An investigation is underway into the cause of the crash, which police say is unknown. Concerns have been raised about the condition of the track at the time of the accident.
Five carriages as well as the locomotive had come off the tracks, officials said.
It was “very lucky” that more people were not killed or injured, police told reporters on Friday.
“It is a tragedy that unfortunately the pilot and the driver were killed in the incident, but I am amazed that there weren’t more passengers at least injured or worse than what they were,” said Insp. Peter Koger.
The train left the tracks at about 19:50 local time on Thursday (08:50 GMT), about 45km (28 miles) north of Melbourne, the state capital of Victoria.
