As the Kongsvinger–Flisa Line was the first railway built by NSB in over a decade, the design of the stations was granted to Paul Due as his début railway project. The stations were characterized by Swiss chalet style, although it was the first steps towards the larger popular Dragon Style. As the first line in Norway, the stations received a through waiting room. Because of the prominence of lumber traffic, each station was set up with the station building on the one side and a lumber terminal on the other. Each platform was long, with the station building in the center and the outhouse and cargo house placed at each end. The latter was built in a dominant Dragon Style. The centerpiece was Flisa, the only first-class station. Kirkenær and Roverud were mid-sized second-class stations, and small, standardized third-class stations were built at Arneberg, Grinder, Namnå and Nor.
