In the present paper, emergency braking simulations are run to tune and validate the model, since the UIC leaflets prescribe the braking distance as a function of the braked weight for emergency braking operations in P position. The leaflet also details the conversion of the braked weight to the braked weight percentage of a The UIC model is thus now able to allow trains of up to m in length to run under ETCS. The components used to control the flow of air (control valve, relay ERTMS UNIT INTRODUCTION TO ETCS BRAKING CURVES.

FigureOverview of the EBD braking curve and its related supervision limits Braking performance can be expressed via a braked weight or via elerations. Nonetheless, the proposed method can be easily extended to other braking regimes and To facilitate consistent use of the braking model, a guidance document was to be provided explaining the key input parameters to deliver reliable results taking into account the requirements of UIC Leaflet The document also contains a comparison between existing signalling systems of different ETCS-equipped networksNotaUntil it is demonstrated that this block is interchangeable with cast iron determining the braking performance.
