It serves the northern suburb of Thomastown, in Melbourne, Victoria, Australia.

Thomastown is a ground-level premium station, featuring two side platforms.

[5] Opening on 23 December 1889, when the railway line was extended from Reservoir to Epping,[5] Thomastown station, like the suburb itself, is named after John and Mary Thomas, who began market gardening near Edgars Creek in 1848.

[13] In 1968, flashing light signals were provided at the Heyington Avenue level crossing, located nearby in the up direction of the station.

[19] As part of the duplication of the line from Keon Park to Epping, a second side platform was added, and the existing station rebuilt.
