[1] Due to the epidemics that ravaged the workforce of the Riihimäki–Saint Petersburg railway throughout the 1860s, a field hospital was established in the village of Okeroinen, in the parish of Hollola, in April 1868.

[1] After the railway was opened for traffic, the locals of Okeroinen appealed to the Railway Administration about the establishment of a station in the village in 1870 and 1893 without result; however, the establishment of a laiturivaihde - a halt with sidings - was finally decided on in 1903, after the municipality of Hollola committed to covering the costs.

Services began on 1 February 1904; passengers were served by local trains 127 and 128 stopping on request.

[1] In the post-war period, Okeroinen briefly held the higher status of a pysäkki (a station of lower significance, translating to "stop"), but it was demoted to an unmanned laiturivaihde in 1967.

The station building was dismantled in 1971; its construction materials were once again reused, this time as a recreational home in Nastola.
