MELBOURNE'S train temptress has struck again.
'However police and rail officials have met to plan an end to her saucy crime spree.
The woman broke into a cabin on a peak-hour Frankston train on Tuesday night and broadcast X-rated praise of the driver to stunned commuters.
The husky-voiced intruder is believed to be the serial seductress behind a similar break-in and announcement on the Sandringham line last week.
The trespasser evaded capture by authorities on both occasions.
As her break-in broadcasts become more frequent, longer and more detailed, pressure is building for Connex to catch the profane prankster before more commuters are subject to her sexy speeches.
"There was a woman on the address system. It was very graphic about how she was going to have sex with a driver for about three minutes," said Angela, a passenger on the Frankston-bound train.
"I thought she was in cahoots with the driver."
Angela said there were families on board unhappy their children were exposed to the content.
Passengers on the trains during both incidents believed the woman was in the cabin with the driver or was a voice on a 1900 sex call.
The broadcasts are now thought to be the work of a lone female hijacking the PA system in vacant train cabins.
Police are scanning CCTV footage from stations to identify her.
Ticket inspectors have been briefed to be on the lookout for the woman.
"When the train comes to a stop at a station it is easy for them to slip out of the cab and merge with other passengers," said Connex spokesman Andrew Cassidy said.
Connex yesterday discussed the incidents with Transit Safety Division officers.
Connex has said some people are aware of a weakness that allows them to force their way into vacant cabins and hijack the PA.
They said the flaw would be fixed this year.
