Boulder railway station was part of the Boulder loopline, a railway that commenced at the Kalgoorlie railway station and travelled south for the purpose of transporting workers to the mines on the Golden Mile in Kalgoorlie-Boulder in Western Australia. In its early days it was also known as the Boulder City Station. Pressure in the early 1900s was for the loopline to be developed, and it was operational by 1903. The loopline in its original form was closed in the 1950s, but the station building and portions of the original loopline remain.
