Preserving the heritage of local private railways: rolling stock and fixed installations beyond the Italian State network

The study examines the preservation of Italy’s non-state railway heritage, focusing on historically private and regional lines that retain significant testimonies of twentieth-century railway engineering. Unlike the national railway network, these lines often preserve original rolling stock, signalling systems, electric traction infrastructure, and operational technologies, thanks to their relative isolation from later standardization processes. Their exceptional heterogeneity reflects complex corporate histories, financial constraints, and repeated adaptations over time. However, the absence of a central coordinating body has hindered coherent conservation strategies. The paper explores possible approaches for safeguarding this fragile heritage, particularly fixed installations and historical traffic-management systems.
