The increasing mobility of the population, as well as the opening of national rail infrastructures to competition, make the need for reliable and durable products more important than ever, both for the rail operators and the infrastructure managers. For years, these topics have been mainly covered by industry standards and in-house specifications, but the recent raise of data collected in operation can be additional fuel for engineers to optimize their design or maintenance strategies, saving time and money. This webinar will cover some examples of how this data can be used to achieve this goal.
