Abstract
A method is described for detecting a braking action of a railway vehicle (RV) comprising monitoring the load transfer to a first axle of the railway vehicle (RV) from a second axle following the first axle according to the direction of travel (d) and, if the load transfer exceeds a predetermined threshold, determining that the railway vehicle (RV) is braking. An emergency braking method is also described comprising detecting an emergency braking request, activating an electrodynamic braking system to decelerate the railway vehicle when the emergency braking request is detected, applying the method to detect a braking action of a railway vehicle and, if so, determining that the electrodynamic braking system is operating correctly and using the electrodynamic braking system to fulfill at least partially the emergency braking request.
