In his capacity as an adviser to a South American railway, one of the two authors had the opportunity of getting a deep insight in the braking technique of mountain railways. This study has been worked out on the basis of the experience gained. According to the authors, the braking performance specification issued by the railways must meet certain fundamental requirements. The study proves that these requirements are not satisfactorily fulfilled on the South American Andes Railways where the UIC operating conditions (also steep downgrades, relatively short trains) are unfortunately combined with the AAR brake system (lightly braked freight trains, direct release air brake subject to depletion). Existing conditions on UIC railways are satisfactory, and the present valid prescriptions by UIC with respect to the minimum brake percentages of the trains are fully correct. The authors suggest the application of the specific energy method as a new procedure for checking the brake tables.
