Evolution lines in the maintenance of rolling stock / Linee evolutive nella manutenzione dei rotabili ferroviari

The article is describes a state of the art on the maintenance of the rolling stock, which - in these last few years - is evolving towards increasingly refined, efficient forms and strategies, aimed at reducing - if not eliminating altogether - any downtime and unnecessary cost. Said new maintenance strategies are progressively being accompanied by technological systems of the latest generation, such as enhanced sensors and artificial intelligence systems. This article intends to define the key ideas of this transformation, which has already occurred in other sectors and is now addressing the railway industry as well, through perspectives of remote diagnostic rooms managed by the rolling stock maintenance operators.
