The disruption of a railway path is one of the most frequent problems that railway companies have to face, as they must reroute their services onto alternative paths, often longer and with lower performances. Companies also need to reschedule their resources to run the connections. This study analyses how the railway company DB Cargo Italia managed the interruption of the Bologna-Prato path from 2021 to 2024 and what challenges will have to face for the line disruption in 2025. By studying the standard tracks, valid all the year, and those diverted during the disruption, it has been possible to evaluate the lengthening of routes and the increase of the need for train crew. Subsequently, the average monthly percentage of execution of the scheduled tracks with resources was studied to understand how many tracks run each month of the year, and the average percentage of train crew presence during the year. By combining these two data with the number of people needed to carry out a circulation, a value that changes based on diverted and standard routes, it was possible to evaluate how many circulations are not assigned to anyone and in which period of the year. The result obtained is that if railway companies face a disruption in summer, they will have lack of train crew and will have to cancel many circulations, while for the rest of the year they can better deal with disruptions, having more availability of people. An interesting point from the study is the need to look for alternative routes to those currently used to reduce travel distances and the need for train crew.
L’interruzione di una linea ferroviaria è uno dei problemi più frequenti in cui le imprese ferroviarie si trovano coinvolte, poiché devono instradare i propri servizi su percorsi alternativi, spesso più lunghi e con prestazioni inferiori. Le imprese devono anche ripianificare le risorse per portare a termine i collegamenti. Questo studio analizza come l’impresa ferroviaria DB Cargo Italia ha gestito l’interruzione della linea Bologna-Prato dal 2021 al 2024 e quali siano le sfide da affrontare per l’interruzione della linea nel 2025. Tramite lo studio delle tracce standard, valide tutto l’anno, e quelle deviate nel periodo dell’interruzione è stato possibile valutare l’allungamento dei percorsi e il conseguente aumento della necessità di personale di condotta per poterli effettuare. Successivamente è stata studiata la percentuale media mensile di effettuazione delle tracce programmate con risorse, per capire quante tracce effettivamente circolino ogni mese dell’anno, e la percentuale media di presenza del personale di condotta durante l’anno. Combinando questi due dati con il numero di persone necessarie per effettuare una circolazione, valore che cambia in base ai percorsi deviati e a quelli standard, è stato possibile valutare quante circolazioni non risultino assegnate a nessun turno di personale e in quali periodi dell’anno. Il risultato ottenuto è che, se le imprese ferroviarie si trovano ad affrontare un’interruzione nel periodo estivo, avranno carenza di personale di condotta e dovranno sopprimere molte circolazioni, mentre nel resto dell’anno riescono a fronteggiare in modo migliore le interruzioni, avendo più disponibilità di risorse. Uno spunto interessante ottenuto dallo studio è la necessità di ricercare instradamenti alternativi a quelli attualmente utilizzati, in modo da ridurre le percorrenze e la necessità di personale.
Come un'interruzione cambia le modalità di gestione dei traffici di un'impresa ferroviaria. Il caso studio della linea Bologna-Prato in DB Cargo Italia

Abstract
The disruption of a railway path is one of the most frequent problems that railway companies have to face, as they must reroute their services onto alternative paths, often longer and with lower performances. Companies also need to reschedule their resources to run the connections. This study analyses how the railway company DB Cargo Italia managed the interruption of the Bologna-Prato path from 2021 to 2024 and what challenges will have to face for the line disruption in 2025. By studying the standard tracks, valid all the year, and those diverted during the disruption, it has been possible to evaluate the lengthening of routes and the increase of the need for train crew. Subsequently, the average monthly percentage of execution of the scheduled tracks with resources was studied to understand how many tracks run each month of the year, and the average percentage of train crew presence during the year. By combining these two data with the number of people needed to carry out a circulation, a value that changes based on diverted and standard routes, it was possible to evaluate how many circulations are not assigned to anyone and in which period of the year. The result obtained is that if railway companies face a disruption in summer, they will have lack of train crew and will have to cancel many circulations, while for the rest of the year they can better deal with disruptions, having more availability of people. An interesting point from the study is the need to look for alternative routes to those currently used to reduce travel distances and the need for train crew.| File | Dimensione | Formato | |
