History
St Marys station opened on 1 May 1862 as South Creek with the construction of the Main Western Line. The name was changed to St Marys on 1 August 1885 after the nearby St Mary Magdalene Church. It is the current western extent of quadruplication of the Western Line built as part of the Blue Mountains electrification in the 1950s, although the original proposal was to extend it through to Penrith.

St Marys was the junction of the former (electrified) Ropes Creek branch line, which opened in 1942. This branch line has been truncated into two storage sidings at the western end of the station and the overhead wiring has been removed.

On 3rd March 1983, 40 people were injured when a 'Red Rattler' failed to stop at the station and derailed at catch-points to the west of the station. The second car had a brake pipe fault and so was isolated, meaning the driver could only control the brakes in the first car. The guard did not realise that he also needed to apply the brakes and so the train was unable to stop in time. The findings from this accident resulted in extensive changes to safety procedures.

As part of the Sydney Metro Greater West, St Marys will become an interchange station. Two new platforms, 5 and 6, will be constructed to serve Sydney Metro services.

Platforms and services
St Marys is served by Sydney Trains T1 Western suburban services. At most times, there are 4 trains per hour, boosted to 8 trains per hour during peak hours. An additional 2 trains per hour start and end at St Marys during peak hours in the peak direction only. These trains do not actually turn around, but run empty to/from Penrith Up Yard.

In the past, a few late night and peak Blue Mountains services made an extra stop at St Marys, along with some other intermediate suburban stations. These stops were removed as part of a timetable change in 2013.

During config 6 trackwork, the Main Western line is closed east of St Marys, so shuttle services run between St Marys and Penrith, using the crossovers at the western end of the station.
