It is located along the Riihimäki–Lahti line, and its neighboring stations are Oitti in the west and Lappila in the east.

It took its name from the estate of Mommila, located approximately 5 kilometres (3.1 mi) away from the station in the parish of Lammi.

In the 1920s, a full station building designed by Thure Hellström replaced the former platform facility.

[3] Mommila became an unmanned station in 1977, its freight transport was abolished in 1990, and its railyard was disassembled in 1997.

[6] Prior to the opening of the Kerava-Lahti railway line, Mommila was also served by the unnamed regional trains on the route Helsinki–Riihimäki–Lahti–Kouvola–Kotka Harbour.
