Dead woman remains nameless for 55 years

For five decades since she was found dead next to railway tracks in Melbourne "female 443" has remained nameless.

But police are hoping to solve the mystery, with an image of a facial reconstruction of the woman, whose body was found in early March 1961 by the line that runs through Alma Park in St Kilda.

Police believe she was about 55 at the time of her death, and they're hoping someone will come forward when they see the image they have released on Thursday.

"There must be someone out there who knew this woman and can help solve this half-century long mystery," Detective Senior Constable Adam Burnett said in a statement.

"It's time for this woman to be given an identity and we can let her loved ones know what happened to her."

The woman is believed to have died of natural causes but an autopsy at the time revealed she had a high level of alcohol in her blood.

She was found wearing a black skirt, red and white blouse, red cardigan, dark grey overcoat and black shoes.

There were no identifying marks or tattoos on her body, but she had a complete set of false teeth.

The woman was given this nomer because she was the 443rd body found in 1961. The number count restarts at the beginning of every year, police told AAP.
