The class III station building was constructed according to plans from Knut Nylander and was later expanded upon twice, in the 1870s and with an additional western wing, designed by Bruno Granholm, in 1900.

Järvelä quickly began to develop with the arrival of the railway and subsequent industry, and took the place of the municipal seat from the Kärkölä church village in the 1930s.

On 18 October 1961, the Railway Administration made the decision to purchase a set of 800 concrete sleepers from abroad, the first of their kind in Finland; in July 1962, they were installed on the section of track between Lappila and Järvelä.

[5] Among the stations on the Riihimäki-Lahti line, Järvelä is an anomaly in that both its passenger and freight transport services continue to operate to this day.

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