The station opened in 1969 as Green Field, later changing to Greenfields.

It is one of only two stations on the Gawler Central line to have a pedestrian underpass (the other is Parafield Gardens). The other stations have had theirs closed due to concerns with safety and vandalism. To the west of the station lies the Australian Rail Track Corporation standard gauge line to Crystal Brook.

In 2021, it has received several upgrades including a deep cleaning, fresh coat of paint, LED lighting and new bins. This is a part of the State governments station refresh program.

Greenfields has two island platforms and is serviced by Adelaide Metro Gawler line services. Trains are scheduled every 30 minutes, seven days a week.
