The stations were designed by Paul Due (1835–1919) and his son, Paul Armin Due (1870–1926). Original stations between Stjørdal and Levanger were designed by Paul Due, while those from Rinnan to Byafossen, as well as Hell Station, were designed by Paul Armin Due. The designs are characterized by the transition period between Dragestil and Art Nouveau, with early stations dominated more by the former and later stations more by the latter. Norway went through a nationalistic period during the construction, and Paul Due chose to replace his older buildings' foreign elements with traditional Norwegian elements. Røra and Byafossen were the only stations not custom designed, while Sunnan was designed by Peter Andreas Blix—as it was originally built at Hell in 1881.
