A man who raped a drunk and drug-affected teenage girl he met at a train station in Perth has been sentenced to five years in prison.

Shane John Anderton was aged 26 in June 2010 when he sexually assaulted the 15-year-old girl in bushland in Fremantle.

Anderton cried as he was sentenced in the West Australian District Court on Friday and must serve at least three years behind bars before he can be eligible for parole.
