The nearby village of Tillola became site for the third field hospital founded for the railway workforce, after those in Oitti and Lahti.

Industry began to settle in Lappila after the arrival of the railway; facilities founded include two sawmills (1897, 1908) as well as brick factories and a furniture workshop.

[3][4] 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.

[a] Construction was completed in 1869; it was later expanded in two phases in 1876 and 1900, with both extensions being designed by Bruno Granholm; the plans were also used for the expansions of the Hikiä station in 1883 and 1904.

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