The previous name of the station, used until 1946, was Turku Itäinen (Swedish: Åbo Östra).

To the east of the station was the populated area of Nummi, which used to belong to the municipality of Kaarina but was annexed to Turku in 1939.

In the 1920s cargo tracks were built from the station to the log sawmill, to the brick factory and to the concrete foundry.

In 1949, a side track was built near the station to the Itäharju industrial area built between the World Wars, but it fell out of use as transport moved from trains to cars, and in 1993 it was dismantled to make way for the new Turku-Helsinki highway.

After that day all passenger trains on the Rantarata line started stopping at Kupittaa again.

[6] Kupittaa railway station has a island platform with tracks (1, 2) on either side.
