La sicurezza ferroviaria rappresenta uno dei pilastri delle politiche di trasporto dell’Unione Europea e si fonda su un approccio evoluto che supera la il concetto di mera conformità normativa, privilegiando la gestione sistemica del rischio e la verificabilità dei processi. Con l’introduzione della Direttiva (UE) 2016/798 e del Regolamento di esecuzione (UE) 2019/779, il IV Pacchetto Ferroviario ha ridefinito il modello di governance della safety, attribuendo alle imprese ferroviarie e ai gestori dell’infrastruttura specifiche responsabilità in materia di sistemi di gestione della sicurezza e di manutenzione dei veicoli. In tale quadro, la figura dell’Entity in Charge of Maintenance (ECM) assume un ruolo centrale nella garanzia dell’affidabilità manutentiva dei rotabili lungo l’intero ciclo di vita, con particolare rilievo per la funzione di esecuzione della manutenzione, in cui le prescrizioni tecniche e normative si traducono in verifiche operative sul veicolo. L’elaborato analizza l’impatto organizzativo e tecnico del modello ECM sulle attività di un’officina manutentiva di secondo livello, attraverso il caso studio dell’OMC Mezzi Leggeri di Foggia di Trenitalia S.p.A., evidenziando come la sicurezza del rotabile al rientro in esercizio dipenda non solo dall’atto manutentivo, ma anche dal controllo degli strumenti, dalle competenze del personale e dalla gestione delle interfacce operative. L’analisi dimostra come la safety ferroviaria sia il risultato di un sistema integrato di responsabilità, tracciabilità e governo del rischio, coerente con i principi europei di interoperabilità e vigilanza affidati alle National Safety Authorities e all’Agenzia dell’Unione Europea per le Ferrovie.

Abstract
Railway safety represents one of the milestone of European Union transport policies and is based on an advanced approach that goes beyond the concept of regulatory compliance, giving priority to systemic risk management and the verifiability of processes. With the introduction of Directive (EU) 2016/798 and Commission Implementing Regulation (EU) 2019/779, the Fourth Railway Package redefined the governance model of safety, assigning specific responsibilities to railway undertakings and infrastructure managers with regard to safety management systems and vehicle maintenance. Within this framework, the Entity in Charge of Maintenance (ECM) plays a central role in ensuring the maintenance reliability of rolling stock throughout its entire life cycle, with particular emphasis on the maintenance execution function, where technical and regulatory requirements are translated into operational inspections on the vehicle. This paper analyses the organisational and technical impact of the ECM model on the activities of a second-level maintenance workshop, through the case study of the OMC Mezzi Leggeri facility in Foggia operated by Trenitalia S.p.A. The study highlights how the safety of rolling stock upon return to service depends not only on the maintenance activity itself, but also on the control of tools, staff competencies, and the management of operational interfaces. The analysis demonstrates that railway safety is the outcome of an integrated system of responsibilities, traceability, and risk governance, consistent with the European principles of interoperability and oversight entrusted to the National Safety Authorities and the European Union Agency for Railways.I documenti in UNITESI sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
