3. Consequences and railway sectors concerned

We're going to take a look at each of the areas concerned in turn, recalling the issues involved and the requirements applicable to TSI (Technical Specification for Interoperability) Class 1 equipment (rolling stock reaching a maximum speed of 250 km/h or more). We'll take the 300-320 km/h speed as our application, as this speed concerns all the areas mentioned. We will present examples of how to resolve or reduce phenomena, test methods and a few calculations.
