GUIDING PRINCIPLES FOR THE DESIGN OF POINTS AND CROSSINGS (UIC 54 AND UIC 60 RAIL PROFILES). GENERAL PRINCIPLES TAKING INTO CONSIDERATION THE INCREASE IN SPEED AND AXLE LOADS

The report summarises developments which have been published in the five preceding documents on this topic. Conclusions regarding the entire study are divided into three ranges of speed in relation to three criteria: security, comfort and maintenance: first for V where security appears to be the most restrictive condition; second for 40 less than V less than or equal to 160 km/h where comfort seems to be the most restrictive and which decides the limit of speed on a turnout according to the actual design of the switches; third: for V greater than 160 km/h where maintenance and layout assume the greatest importance in proportion to the cost they in volve in the general economy.
