Authorities say they are 'appalled' and 'disgusted' after a train station in Victoria was used as the set for an amateur porn film.

The eight-minute film, called Trainline Tramp, was recorded at North Shore Railway Station, in Norlane, back in April but has just come to the attention of train bosses.

It features Melbourne graffiti artist Staytrue, known for creating murals while dressed in little more than a short skirt or lingerie.

V/Line spokesman Rob Curtain confirmed that authorities are aware of the video, but would not offer further comment.

He said bosses were 'appalled and disgusted' by the behaviour depicted.

Police and railway bosses say they are working together to try and identify those involved in making the film so they can be prosecuted.

The footage depicts several sex acts on a bench toward the end of the platform (right) as well as full intercourse

The footage depicts Staytrue walking on to the platform in a short skirt, in similar fashion to other films of her work.

She then attempts to tag a railway shelter before being 'caught' by a man wearing a mask over his face.

The pair then perform several sex acts on a bench toward the end of the platform, including full intercourse.

Staytrue has a cult following on Facebook where she posts images of herself painting on trains while wearing revealing clothing
