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.

For a period prior to the expansion of the Kalgoorlie Super Pit gold mine the loopline railway was able to have operations on part of the original railway.

[4] Recent expansion of the Super Pit has erased most of its former route, but the Goldfields loopline railway is headquartered at the station and in 2015 the state government allocated funds to rebuild the line.

[5] The railway station operates currently as a museum and revenue raiser for the Loopline organisation.

[6] The railway station forecourt, across from the Hamilton and Burt Street roundabout, houses the Boulder war memorial.
