The Prospector is a rural passenger train service in Western Australia operated by Transwa between East Perth and Kalgoorlie.

The new service commenced on 29 November 1971, cutting the 653-kilometre (406 mi) journey time from fourteen to eight hours.

At every seat there is a touchscreen entertainment system with a small selection of movies, TV shows and music.

The buffet offers a variety of items such as ham and cheese croissants, pies, muffins, soft drinks, potato chips, lollies and alcohol.
